The CMT 663.150.11 V-Groove and Folding CNC Bit is a high-performance CNC router cutter engineered for a wide range of precision woodworking operations, including V-groove routing, miter folding, signmaking, lettering, and chamfer edge work. Built on a super-strength steel body and fitted with high-grade reversible HW (carbide) insert knives, this 150 deg. bit delivers consistent, repeatable results across chipboard, plywood, MDF, solid hardwood, softwood, and laminated panels. With a large 3-51/64" cutting diameter and a 20mm shank designed for CNC router machines, it is an ideal tool for production shops and professional CNC operators who need versatility and reliability in a single bit.

Key Features

• 150 deg. V-groove cutting angle - produces wide, shallow V-profiles ideal for miter folding, panel scoring, decorative lettering, and chamfer edge work, giving operators flexible output from one tool
• 3-51/64" cutting diameter - covers broad surface passes in fewer tool paths, reducing machining time and improving throughput on large panels
• High-grade HW (hardmetal carbide) reversible insert knives - knives can be rotated to a fresh cutting edge rather than replaced immediately, reducing tooling costs and downtime during production runs
• Super-strength steel body - resists flex and vibration at CNC operating speeds, contributing to cleaner cuts and longer tool life
• 2-tooth (2-flute) configuration - balances chip evacuation and cutting speed for smooth surface finishes across a wide range of panel materials
• 20mm shank - designed to seat securely in CNC router collets for vibration-free operation and consistent dimensional accuracy
• Right-hand (RH) rotation - compatible with standard CNC router spindle configurations, making setup and integration straightforward
• Compatible with both general-purpose and premium knife grades - a higher-quality insert is available for demanding materials like laminates and MDF, so the same tool body can be upgraded for specialty applications
• 95mm total length - provides sufficient reach for typical CNC router setups while maintaining rigidity and minimizing runout

Why This Product

• A single 150 deg. V-groove bit handles V-grooving, miter folding, signmaking, lettering, and chamfering - eliminating the need to swap between multiple specialized tools during production
• Reversible HW insert knives mean worn edges can be rotated rather than discarded, extending the useful life of each insert and lowering the per-cut cost for high-volume CNC operations
• The wide 3-51/64" diameter makes this cutter well suited for large-format panel work where coverage per pass matters, such as V-scored folding panels, cabinetry components, and dimensional signage
• A higher-quality knife grade is available for the same tool body, making this bit a scalable solution for shops that cut both standard chipboard and plywood as well as more demanding laminated and MDF substrates
