1/4" Starter Set | 5-Piece CNC Router Bit Kit | 1/4" Shank

Everything you need to get started with a 1/4" collet, in one case — and at a better price than buying each bit individually. This five-piece starter set from Centurion Tools bundles the geometries you'll reach for most in a cabinet shop, sign shop, or general woodworking environment, all with 1" cut length, FEM geometry, and a 1/4" shank. Buying the set saves you 5% off the individual prices.

The set includes:
• 1/4" Upshear Spiral – 1" cut length, FEM. Your go-to for clean bottom surfaces, fast chip evacuation, and general-purpose routing in wood, MDF, and plywood.
• 1/4" Downshear Spiral – 1" cut length, FEM. Use this when top surface quality matters — veneered panels, laminates, and melamine where tearout isn't acceptable.
• 1/4" Compression – 1" cut length, FEM. The best of both: clean top and bottom faces in a single pass through veneered plywood and finished panel goods.
• 1/4" Mortise Compression (.200" upcut length) – 1" cut length, FEM. Optimized for dadoes, slots, and blind grooves where both cut faces need to be clean.
• 1/4" Straight Flute – 1" cut length. Zero-helix geometry for controlled, accurate cuts with no workpiece lift — great for thin stock and precise slotting.

All five bits ship in a Centurion Tools protective tool case for safe storage and easy transport. Solid carbide throughout, Made in the USA by Centurion Tools LLC.
