Router Bit & CNC Tooling Sharpening
Frank’s Industrial Sharpening regrinds router bits and CNC tooling back to spec, including spiral, compression, straight and insert tooling, for cabinet shops, millwork, sign makers and furniture plants.
Mail your tooling in from anywhere in the U.S., or use our route pickup and delivery across Florida and South Georgia.
What router bits and CNC tooling do you sharpen?
Nested-Based to Hand-Fed
We sharpen production CNC tooling and router table bits with the same grind quality: upcut, downcut and finishing spirals, compression bits for laminates and plywood, straight and pattern bits, insert tooling, production cutters and custom profiles, in both solid carbide and carbide-tipped.

How is a router bit sharpened?
Reground to Cut Like New
A router bit's performance lives in its flute geometry; rake, relief, and edge quality decide whether it slices or burns. We regrind on CNC tool grinders that follow the bit's original helix and angles rather than flattening them away, so a resharpened spiral behaves like the one you unboxed: same chip load, same finish, a slightly smaller diameter you can offset in a period:
-
Inspect — each bit checked for chipped edges, wear land, and remaining regrind life
-
Grind — flutes and edges restored along the original geometry on CNC equipment
-
Final check — edges verified by hand before the batch ships back
Can a chipped router bit be sharpened?
Chipped Edge? Worn Past Spec?
A chipped carbide edge can often be ground down, and the bit returned to service. Custom and production tooling with damaged inserts or brazed tips can usually be repaired rather than replaced. Send a photo before you scrap anything, especially the expensive stuff.
Who we sharpen for
Built for Shops That Run CNC All Day
Cabinet shops, closet and millwork manufacturers, sign makers, and furniture plants cycle their CNC router bit sharpening through us in batches, a tooling bin that ships when full and comes back cutting like new.
Mail-in from anywhere, route pickup, or drop-off; small tooling ships cheaply and safely.
