The CMT 663.201.11 Adjustable Chamfering CNC Router Bit is a precision-engineered heavy-duty cutting tool designed for CNC router machines requiring variable-angle chamfering on a wide range of wood-based materials. Built with a hardwood-grade carbide (HW) cutting head and a robust steel tool body, this 2-flute right-hand rotating bit delivers clean, accurate chamfers at any angle from 0 deg. to 45 deg. - and full 0 deg. to 90 deg. range - making it a versatile solution for production CNC environments, furniture manufacturing, cabinetry, and composite panel processing.

Key Features

• Adjustable chamfering angle range of 0 deg. to 45 deg. (0 deg. to 90 deg. full range) - dial in the exact bevel needed for any profile without swapping bits, saving setup time and reducing tooling inventory on the shop floor.
• 85mm (3-11/32 in.) cutting diameter with 39.5mm cutting height - provides a wide, deep chamfering envelope suited to thick stock, edge detailing, and high-volume CNC panel work where a single pass matters.
• Maximum diameter expandable to 102mm (4-1/32 in.) - the adjustable body allows diameter expansion to accommodate larger workpieces, adding flexibility that a fixed-geometry bit simply cannot offer.
• HW (hardwood-grade carbide) cutting material - delivers the hardness and wear resistance needed to cut solid hardwood, MDF, chipboard, plywood, laminates, and softwood cleanly and consistently over extended production runs.
• Steel tool body construction - a rigid, dimensionally stable body minimizes vibration and deflection at CNC spindle speeds, contributing to tighter tolerances and a smoother finished chamfer edge.
• 20mm shank diameter - matches industrial CNC router spindle collets for a secure, concentric grip that reduces runout and supports stable operation across the full 7,500-12,000 RPM operating range.
• Right-hand (RH) rotation with 2 cutting teeth - the twin-flute geometry balances cutting forces evenly, helping produce a consistent chamfer surface finish while keeping the bit tracking true through the cut.
• 3-5/8 in. total length - provides clearance for deep setups and workholding fixtures common in CNC routing applications without compromising rigidity.

Why This Product

• The adjustable angle design - spanning 0 deg. to 45 deg. (0 deg. to 90 deg. full range) with a maximum diameter of 102mm - means one tool can replace multiple fixed-angle chamfer bits, streamlining the toolchanger carousel and lowering total tooling costs in production CNC environments.
• The 20mm shank paired with a hardwood-grade carbide cutting head makes this bit well-matched to industrial CNC router machines cutting demanding materials like solid hardwood, laminates, and MDF where edge quality and tool longevity both matter.
• With an operating range of 7,500-12,000 RPM, this bit is sized and engineered for professional CNC spindle speeds - not handheld routers - giving operators the speed consistency needed for repeatable, production-quality chamfered edges.
• The combination of adjustable geometry and a 39.5mm cutting height means this cutter can handle variable bevel profiles in a single tool setup, reducing changeover time on multi-profile CNC programs.
