Cutting Tool Supply, Handled Like an Engineering Conversation
InsertCore is a carbide inserts & cnc cutting tools supply brand based in Guangzhou, China — every enquiry is answered by the person who will also stand behind the recommendation.
WHO WE ARE
A Trading Brand Built Around the Machinist, Not the Warehouse
Most buyers our age have the same complaint: catalog numbers are easy to find, but nobody answers questions about why an insert is chipping, why aluminum keeps welding to the flute, or which coating actually pays off in their specific cut. We started InsertCore to close that gap — a focused tooling desk that reads your application before it quotes a part number.
We work with vetted carbide-tool production partners and pass their published specifications straight to you — substrate grade, coating process, edge preparation and ISO tolerance class — with nothing added that the data sheet does not carry. If a job is outside what we supply well, we say so before money changes hands.
One Insert Desk
Turning, milling, drilling and threading grades in one quote — ISO indexable families plus CBN and PCD superhard tooling, so you consolidate spend instead of chasing five suppliers.
Application-First Advice
Send us your workpiece material, machine and parameters — we recommend grade, geometry and coating against published ISO application ranges, not against a stock list we need to clear.
Small-Order Friendly
Trial quantities from single boxes up to distributor pallets. First orders are meant to be tested on the shop floor, not warehoused.
Worldwide Shipping
Air and express with tracking on in-stock lines; consolidated sea freight for volume. Invoice and packing documentation included on every shipment.
