The CMT 663.120.11 V-Groove and Folding CNC Bit is a high-performance CNC router cutter engineered for precision V-grooving, miter folding, signmaking, lettering, and chamfer edge work. Built on a super strength steel body and fitted with a high-grade HWM reversible knife, this 120 deg. insert cutter delivers consistent, clean results across a wide range of panel and sheet materials. Whether you are routing decorative V-channels into solid wood, creating folded panel joints in cabinetry, or cutting crisp lettering into signage, this CMT two-flute right-hand rotation bit gives your CNC router the versatility to handle general purpose, chipboard, plywood, and with the appropriate knife grade, laminated panels and MDF as well.

Key Features

• Super strength steel body - provides a rigid, vibration-resistant platform that supports accurate, repeatable cuts during high-speed CNC operations.
• High-grade HWM reversible knife - the replaceable, indexable knife design reduces tooling costs because worn edges can be rotated rather than replaced entirely, keeping the bit in service longer.
• 120 deg. V-groove geometry - produces a wide, shallow V-profile ideal for miter folds, chamfer edges, and broad decorative grooves that shallower-angle bits cannot achieve.
• 20mm shank diameter - matches heavy-duty CNC router spindle collets for a secure, low-runout grip during demanding production passes.
• 24mm cutting height - allows the bit to engage material at depth in a single pass, improving efficiency and surface finish on thicker panels.
• Two-flute right-hand rotation - balanced two-tooth configuration supports smooth chip evacuation and reduces heat buildup, contributing to cleaner cut edges.
• Versatile application range - a single bit handles V-groove routing, miter folding for box and cabinet construction, signmaking, and lettering, reducing the need for multiple specialized tools.

Why This Product

• The 120 deg. angle is specifically suited for wide miter folds and flat chamfer profiles that are common in modern cabinetry and signage production, making this bit a practical choice for shops that work with folded panel construction or decorative V-channeling.
• The HWM reversible knife system means you can restore cutting performance without purchasing a completely new bit, lowering the per-job tooling cost in a busy CNC production environment.
• The 20mm shank and 95mm total length are matched to industrial CNC router spindles, making this bit a direct-fit solution for production routers without the need for adapters or custom setups.
• A single tool covers V-grooving, miter folding, chamfering, lettering, and signmaking across chipboard, plywood, solid wood, and with the appropriate knife grade, laminates and MDF - reducing tool change downtime on multi-operation CNC programs.
