CMT Pair of Knives for Roundover and Chamfer (Bottom) - R=3mm plus 45 deg. by CMT are precision-ground carbide profiling knives designed to produce a clean 3mm roundover combined with a 45 deg. chamfer on the bottom edge of a workpiece. Sold as a matched pair, these HW (tungsten carbide) knives are engineered for use in compatible CMT spindle moulder cutter heads, delivering consistent, repeatable profiles across a wide range of wood-based materials including hardwood, softwood, plywood, MDF, and chipboard. Whether you are profiling solid timber on a spindle moulder or shaping edges on a profiling machine, this knife pair brings industrial-grade accuracy to workshop and production-floor applications alike.

Key Features

• Dual-profile geometry - R=3mm roundover plus 45 deg. chamfer (bottom): a single knife pair handles two profile elements simultaneously, reducing setup time and producing a refined finished edge in one pass.
• Tungsten carbide (HW) material: carbide construction maintains a sharp cutting edge significantly longer than high-speed steel alternatives, meaning fewer knife changes and more consistent results over extended production runs.
• 20mm diameter and 20mm cutting height: these dimensions are sized to match compatible CMT cutter head bodies, ensuring secure seating and accurate profile alignment with no guesswork during installation.
• Precision-ground profile: each knife is ground to exact profile specifications, so the roundover and chamfer geometry is accurate and repeatable from the first cut to the last.
• Sold as a matched pair: both knives are included in a single order, so you receive a balanced, ready-to-install set without needing to source individual blades separately.

Why This Product

• The combined R=3mm roundover plus 45 deg. chamfer profile gives woodworkers and cabinetmakers a versatile bottom-edge treatment in a single tooling setup - ideal for furniture components, door parts, and decorative mouldings where a refined profile edge is required.
• Carbide (HW) construction means these knives hold their edge through demanding production work on hardwood, MDF, and composite panels, reducing downtime compared to softer knife materials.
• Designed specifically to pair with CMT cutter head systems, these knives integrate with an established tooling platform, supporting quick changeouts and consistent profile repeatability across multiple production runs.
• Purchasing as a matched pair ensures balanced cutting performance and simplifies inventory management - you always have a complete, balanced knife set on hand for the next job.
