Diamond Saw Blade OEM: What to Provide Before Production

2026-10-12 0 Leave me a message

OEM diamond saw blades only work out if the spec is right before the first segment is sintered. This is the exact information sheet we ask every private-label buyer to send — diameter, bore, segment height, dry or wet cut, silent slots, logo and shipping marks — plus why each point changes the blade you receive.

Why the spec sheet decides everything

A diamond saw blade looks like a simple disc of steel with teeth. It is not. Every choice — core thickness, segment height, bond hardness, welding method, slot pattern — is locked in when the first production order is released. A blade built to the wrong bond for your market's concrete will cut slowly and overheat; a blade with the wrong bore will not fit your customer's saw at all; a blade marked for dry cutting but sold into a wet-cutting market creates a compliance problem, not just a performance one.

We have produced diamond tools for nearly two decades at our 20,000 m² ISO 9001-certified plant, exporting to more than 50 countries. The pattern is consistent: the buyers who send a complete spec sheet get samples approved in one or two rounds. The buyers who send "300mm blade for concrete, your best price" get three rounds of samples and a delayed season. This page tells you exactly what to send so your OEM programme starts right.

The 10-point OEM spec sheet

Copy the table below into your inquiry. Anything you leave blank, we will fill with our standard assumption — and flag it clearly so you can confirm.

diamond saw blades

#	Spec item	What to tell us	Why it matters
1	Material to cut	Reinforced concrete, green concrete, asphalt, granite, marble, porcelain tile, ductile iron — and whether rebar is common in your market	Drives diamond grit, concentration and bond hardness. Abrasive asphalt needs a completely different bond from hard granite.
2	Blade dimensions	Diameter × core thickness × bore, in mm — e.g. 300 × 3.0 × 22.23 mm	Sets the core steel, tooling and test speed. Bore precision matters: 7/8" is 22.23 mm, not 22.2 mm — a 0.03 mm error is a saw that vibrates.
3	Segment height	Segment (diamond tooth) height in mm — commonly 7–18 mm — and segment width	Taller segments cut deeper and last longer per pass, but expose more steel to abrasion and raise the risk of segment loss if the bond is too hard for the material.
4	Dry or wet cut	Dry, wet, or both — see the comparison table below	Changes the bond formulation and the welding method. Dry cutting runs hot and usually needs a laser-welded core.
5	Silent slots	Yes / no; if yes, standard two-slot pattern or your drawing	Silent slots are cut into the core with a laser. They cannot be added after production — the core is made with them or without.
6	Bond & performance target	Soft / medium / hard bond preference, target cutting life in linear metres, and the competitor blade you benchmark against	A benchmark blade is the fastest way for our lab to match the feel your customers expect.
7	Logo & branding	Vector artwork (AI/PDF/CDR), engraving position on the core, and whether the logo also goes on the label and carton	Laser engraving is permanent; screen print is cheaper but wears under slurry. Vector artwork avoids redraw fees and delays.
8	Packaging	Cartons, inner boxes, plastic clamshells, or your own retail pack — and how many blades per unit	Retail-ready packaging for hardware stores needs different tooling than bulk cartons for contractors.
9	Shipping marks	Marking text, layout or artwork — see the shipping mark section below	Correct marks prevent customs holds, especially for US entries with AD/CVD reporting requirements.
10	Quantity, market & documents	Order quantity per size, MOQ expectations, destination market, and required certificates (CE, EN 13236 marking, test reports)	Quantity per size drives pricing; the destination market decides which marking and trade measures apply.

Expert detail worth knowing: blades of 300–400 mm used on hand-held cutting-off machines are typically rated to 100 m/s maximum operating speed, because the machines these blades are used on run faster than 80 m/s. If you are quoting a 300 mm blade, confirm the speed rating with your saw's manual before ordering — and tell us, so we mark it correctly under EN 13236.

Dry cut vs. wet cut: the decision that changes the build

This is the single most common gap between what a buyer orders and what their customers actually do. Wet cutting uses water to cool the blade and suppress silica dust — the default for concrete and stone on hand-held saws, and recommended wherever possible because dry cutting stone without respiratory protection creates an incurable silicosis risk. Dry cutting happens on chop saws and road repair jobs where there is no water supply, and the blade runs dramatically hotter.

Aspect	Wet cut	Dry cut
Cooling	Water removes heat and flushes slurry	Air only — the core and bond must shed heat by design
Typical welding	High-frequency (induction) welded segments are standard	Laser-welded core strongly preferred; high-frequency joints can fail when overheated
Bond	Standard formulation, softer bonds cut fast on hard concrete	Bond formulated for higher temperature and dry abrasion
EN 13236 restriction code	RE10 = only permitted for wet cutting-off	RE3 = not permitted for wet cutting-off
Dust	Suppressed by water; slurry cleanup required	High silica dust — needs dust extraction or respirator on site

Tell us which regime your customers use and we mark the blade with the correct restriction code. A blade that arrives with the wrong code is a compliance problem at the point of sale, not just a performance complaint.

Silent slots: quiet by design, not by printing

Silent slots — laser-cut openings in the core near the segments, usually in a symmetric pattern — break the vibration that makes a cutting blade whistle. A slotted blade runs measurably quieter, stays cooler, and clears chips better, which is why they are standard on the mid-to-premium blades sold in hardware retail. Because the slots are cut into the steel core during core production, they must be specified before the order is placed; they are a geometry, not a graphic. If your market is municipal or indoor work where noise complaints are common, silent slots are usually worth the small cost delta.

Your logo on the blade

Private-label OEM is our core business, and branding is straightforward once you send the right files:

· Laser engraving on the core — permanent, cannot be rubbed off by slurry or cleaning. Standard for distributor brands. We will confirm the engraving size against the blade diameter; on a 105 mm blade there is simply less room than on a 400 mm wall saw blade.

· Screen printing on the core — cheaper per unit, fine for lighter retail use, but wears faster under abrasive slurry.

· Segment-side or label marking — some programmes mark the part number and application code on the label only; this is the cheapest route but weakest for brand visibility on site.

· Private label under an oSa label — if you sell under the oSa safety label, a private label number is required on all private label products bearing the oSa logo. Send us your private label number with the artwork.

Send vector artwork (AI, PDF or CDR), not raster images. A redrawn logo from a low-resolution PNG is the most common cause of a delayed first

shipment — it is a five-minute fix at your end and a two-week problem at ours.

Shipping marks: what to print and why it matters

Shipping marks — the 唛头 printed on cartons and pallets — are often treated as an afterthought, and they are exactly where OEM shipments get held at customs. A workable mark is short, scannable, and identical across the whole shipment:

Mark element	What it says	Why it matters
Consignee / your brand	Your company name or agreed abbreviation	First identification at the port and in the warehouse
PO number	Purchase order reference, exactly as on your documents	Ties the carton to the order during inspection and claims
Product code & size	Your SKU plus diameter × thickness × bore	Lets your warehouse pick without opening cartons
Quantity & carton numbering	Pieces per carton, carton X of Y	Shortage claims are settled against carton numbers
Weight & dimensions	Net and gross weight, carton size in cm	Freight quoting and pallet planning
Country of origin	"Made in China" (or as applicable)	For US entries, origin marking must be legible, permanent and conspicuous under the marking rules your broker will confirm
Handling marks	Fragile, this way up, keep dry, stack limit	Blades arrive unbent — the most common transit damage is a crushed corner carton
Trade-measure reference	AD/CVD case number where required	For US entries of diamond saw blades, the AD/CVD case number (A-570-900) goes on the entry line alongside the HTS number

US buyers, read this twice: the antidumping and countervailing duty order on diamond sawblades and parts from China (A-570-900) has been in force since 2009 and was continued after a sunset review in 2021; a new sunset review was initiated in March 2026. The written scope description — not the HTS code — is what decides whether your blade is in scope, and the scope excludes, among others, blades thinner than 0.025 inch or thicker than 1.1 inch, and blades where the diamond is bonded by resin or electroplating without segments. Confirm scope, classification and current deposit rates with a licensed customs broker before you price an order. We do not publish rate figures because they change with each administrative review.

Terminology: English ↔ 中文, and common mistranslations

If your team works in both English and Chinese, keep this table next to the spec sheet. Cross-language searches like "刀头英文怎么说" are common, and using the right term avoids the translation traps that cause real production errors:

English	中文	Notes
segment	刀头	The diamond-containing tooth welded to the core; its height is a core spec item
bond matrix	胎体	The metal powder that holds the diamond; hardness is matched to the material
core / steel core	基体	The steel disc; silent slots and laser welding live on this part
bore / arbor hole	轴孔	7/8" = 22.23 mm — convert exactly, never round to 22.2 mm
gullet / silent slot	排屑槽 / 静音槽	Laser-cut openings in the core for noise, heat and chip clearance
dry cutting / wet cutting	干切 / 湿切	Decides bond and welding method; EN 13236 codes RE3 vs RE10
laser welding	激光焊接	Stronger joint, supports dry cutting; not the same as high-frequency welding
high-frequency welding	高频焊接	Standard for wet-cut blades; translating both weld types as "welded blade" hides a critical difference
sintering	烧结	How segments are made; not "curing", which belongs to resin-bond wheels
shipping mark	唛头	The carton/pallet marking block specified in your spec sheet

FAQ

What is the minimum information you need to quote an OEM diamond saw blade?

At minimum: the material you will cut, blade diameter, core thickness, bore (arbor) size, segment height, and whether you cut dry or wet. With those six points we can quote a working spec. Add quantity, target price and destination market and we can also advise on certifications, packaging and shipping marks.

Does dry cut or wet cut change the blade design?

Yes, significantly. Wet cutting cools the blade and suppresses silica dust, so standard high-frequency welded segments work well. Dry cutting runs much hotter, so we normally recommend a laser-welded core with a bond formulated for dry use, and the blade must be marked with the correct EN 13236 restriction code — RE3 means not permitted for wet cutting-off, RE10 means only permitted for wet cutting-off. Telling us which one you intend avoids a blade that arrives mis-marked or fails on site.

What do silent slots on a diamond blade actually do?

Silent slots — also called gullets or silencing slots — are laser-cut openings in the steel core, usually on both sides of the segments. They break the vibration pattern that makes a cutting blade whistle, so the blade runs measurably quieter, and they also help with heat and chip clearance. They are a core design feature, not a printing option, so they must be decided before production, not added later.

Can you put our logo on the blade itself?

Yes. The most common method is laser engraving your logo and part number on the core, which is permanent and cannot be rubbed off; screen printing on the core is cheaper but wears faster under abrasive slurry. For private-label programmes sold under an oSa label, note that a private label number is required on all private label products bearing the oSa logo. Send us vector artwork and we will confirm the engraving size against the blade diameter before the first batch.

What should our shipping marks include?

A workable shipping mark carries your company name or abbreviation, purchase order number, product code, quantity, net and gross weight, carton dimensions, destination port, country of origin, and handling marks such as fragile or this way up. For US entries, country-of-origin marking must be legible, permanent and conspicuous, and the AD/CVD case number A-570-900 should be reported on the entry line. We will print the marks you specify and confirm a mark proof before shipment.

Which certifications should we ask about for EU and US markets?

For the EU, diamond blades sold on hand-held cutting-off machines are marked under EN 13236, which requires ten marking elements — the first nine are mandatory and the PPE pictogram is mandatory in France. For the US, confirm the HTS classification (diamond saw blades typically fall under 8202.39.00) and the current status of the antidumping and countervailing duty order on Chinese diamond saw blades with a licensed customs broker, because deposit rates and scope rulings change. We produce under ISO 9001 and can supply the documents your market requires.
