CMT 836.420.11 Chamfer Bit with Bearing by CMT is a precision router bit designed to cut clean, accurate 45 deg. bevels and chamfers on wood edges and surfaces. With a 1 49/64 in. cutting diameter, a 23/32 in. cutting height, and a 1/4 in. shank, this bit handles everything from decorative edge profiling to multi-sided box construction and large-scale architectural elements like beams and columns. The ball-bearing guide ensures repeatable, consistent results pass after pass, making it a reliable choice for furniture makers, cabinet builders, and woodworking enthusiasts alike.

Key Features

• 45 deg. chamfer angle - delivers a precise, flat angled bevel that creates clean decorative edges, eases sharp corners, and enables perfectly aligned joints for boxes and multi-sided containers.
• 1 49/64 in. cutting diameter with 23/32 in. cutting height - provides ample material contact for full, consistent chamfers on thicker stock without requiring multiple passes.
• Ball-bearing guide - rides smoothly along the workpiece edge to control cut depth automatically, ensuring a uniform bevel profile without the need for additional fences or guides.
• 1/4 in. shank - fits a wide range of handheld routers and router tables, making this bit highly versatile across common workshop setups.
• HW (tungsten carbide) cutting material - hard-wearing carbide construction maintains a sharp cutting edge longer, reducing the frequency of replacements and keeping your workflow moving efficiently.
• 2-flute design with right-hand rotation - the twin-flute geometry produces smooth, chip-free cuts and efficient material removal, resulting in surfaces that require minimal sanding or finishing.
• 2 3/8 in. total length - compact overall profile that maintains rigidity and reduces vibration during operation, contributing to cleaner cuts and improved control.

Why This Product

• The integrated bearing guide eliminates the guesswork from edge work - the 45 deg. chamfer angle is locked in automatically, so both beginners and experienced woodworkers achieve professional-looking bevels consistently.
• The 23/32 in. cutting height is well suited to a broad range of stock thicknesses, making this bit effective for decorative projects like keepsake boxes as well as larger structural work on beams and columns.
• The 1/4 in. shank provides broad compatibility with compact and full-size handheld routers as well as router tables, giving this bit genuine versatility across different machine types in the same shop.
• Tungsten carbide cutting edges hold their sharpness through extended use on solid hardwood, softwood, plywood, and other common materials, reducing downtime and keeping production efficient.
