The last blade in the box has to cut like the first.

Not better — identical. Diamond grit and bond powder are not uniform materials, and a blade is born in a mould, under heat and pressure, in a batch of hundreds. Anyone can make one good blade. The work is making the next hundred behave like it, and the hundred after that. That is the whole of the job.

Where this started

EXTRACUT began in Hangzhou in 2007 with a narrow brief: make the tools that come back on the second order. Not the widest catalogue, and not the cheapest line in it. Nineteen years later that brief has grown into 248 models — diamond blades, T.C.T. circular saw blades and brazed diamond core drill bits, plus what a crew reaches for around them: cutting and grinding discs, abrasives, hole saws, turning tools, hand tools and complete kits. The name is a brief too, not a badge: extra cut, out of every blade, on every shift.

What we will not claim

We will not tell you our tools are perfect. Diamond and sintered products vary by nature; anyone who says otherwise has never stood at a sintering press and watched a batch come out of the mould. What a manufacturer can honestly do is narrow the variation — and then show the work.

Three things that have not changed

• ▪We sample what comes in. Every batch of diamond grit, bond powder and steel substrate is measured and logged before it reaches a line.
• ▪We spin what goes out. Every blade runs at full RPM before it is boxed. It costs time on a busy line. We keep it, because a blade that has never spun is a claim, not a tool.
• ▪We answer with a number. Tell us the material you cut and the machine you run it on, and you get a specification and a price within one business day — not a promise to come back to you.

Behind those three sit seven controlled stages and 17 checkpoints on every order.

How to check us

None of it is worth much if you have to take it on trust. Samples come before volume orders. Send us the drawing and our engineers return a 3D CAD prototype within 72 hours. Private-label programmes — your logo, your packaging, your colours — start from 100 pieces.

From Ningbo and Shanghai we ship to more than 50 countries, by sea, air, rail or express, on FOB, CIF or DDP terms. HS codes are pre-classified per SKU, and the full export document set is issued within two working days.

We are still not the biggest name in the catalogue. We are working on being the one you stop having to check.
