Cutting Tools

Cutting tools for production machine shops.

End mills, drills, inserts, taps, reamers, boring bars and the holders that run them — with the full spec on every listing, so you can match a tool without calling anybody. And when the catalog runs out, we regrind, cross-reference and build specials.

Tool Mart Supply is a Cerritos, California cutting tool distributor serving machine shops across Los Angeles and Orange County and shipping nationwide. The catalog runs to well over a hundred thousand items across the round tooling and indexable lines, listed with the dimensional and material specs machinists actually search on — diameter, flute count, length of cut, overall length, shank, coating, corner radius, ISO insert designation — rather than a photo and a part number.

That depth is the point. If you know the size and the material, you should be able to land on the right tool yourself in under a minute. If you only have a competitor’s part number, a worn tool in your hand or a print, that’s what the services below are for.

Three ways to find the tool

Search the part number

Manufacturer part numbers are indexed directly. Type the number — with or without dashes — and the tool comes up. Inserts also match on their ISO designation, so CNMG432 finds what you’d expect.

Filter by spec

Every listing carries its dimensional and material specs. Narrow a category by diameter, flute count, length of cut, shank, coating, insert style or corner radius until one tool is left.

Browse end mills

Send us the number you have

Discontinued, competitor-branded, or a number off a tool nobody can identify. Send it and we’ll match it to a spec-equivalent from the lines we carry.

What we do beyond the catalog

Regrinding

Dull end mills, drills and carbide burrs resharpened to spec and returned ready to run — at a fraction of replacement cost, with optional PVD recoating in the same pass.

Regrinding services

Custom & special tools

Special diameters and lengths, step drills, form tools and modified standards — designed and sourced from your print, a sketch or a photo of the feature.

Custom & special tools

PVD coatings

Nine coatings from TiN to AlTiSiN, applied on a local Southern California line so tools don’t cross the country to get coated. New tools or reground ones.

PVD coatings

Cross-reference

A competitor part number, a discontinued tool or a number off an old bin label — matched to a spec-equivalent we can quote and ship.
