CMT Chamfer Bit with Bearing - 1-1/4" Diameter, 7/8" Cutting Height, 22.5 deg. Angle, 1/2" Shank is a precision routing bit from CMT designed to cut clean, accurate bevels and chamfers on a wide range of wood and wood-composite materials. Whether you are profiling decorative edges, assembling multi-sided boxes and containers, or working larger architectural elements like beams and columns, this 22.5 deg. chamfer bit delivers consistent, repeatable results with its ball-bearing guide and 2-flute tungsten carbide construction. The right-hand rotation and 1/2" shank make it compatible with handheld routers, router tables, and CNC routing machines.

Key Features

• 22.5 deg. Chamfer Angle - produces precise bevel cuts ideal for multi-sided assemblies such as octagonal boxes and decorative containers where consistent miter angles are critical to a tight fit.
• Ball-Bearing Pilot Guide - rides along the workpiece edge to maintain a consistent chamfer depth and position throughout the cut, reducing the need for fence setups and improving repeatability.
• HW (Tungsten Carbide) Cutting Material - hard-wearing carbide tips stay sharp longer when cutting solid hardwood, softwood, plywood, MDF, and similar materials, reducing the frequency of sharpening or replacement.
• 2-Flute (2-Tooth) Design - dual cutting edges distribute load evenly across the bit, resulting in a smoother surface finish and more balanced cutting performance.
• 1/2" Shank - the larger shank diameter reduces vibration and chatter compared to a 1/4" shank, improving cut quality and extending bit life during edge profiling work.
• Right-Hand Rotation - standard RH direction is compatible with virtually all handheld routers, router tables, and CNC routing machines without special configuration.
• 1-1/4" Cutting Diameter x 7/8" Cutting Height - provides sufficient material engagement for chamfering thicker stock and larger workpiece edges in a single pass.

Why This Product

• The 22.5 deg. bevel angle is specifically suited for constructing 8-sided (octagonal) projects - when eight identically chamfered panels are joined, the angles close perfectly, making this bit a purpose-built tool for decorative box and column work rather than a general-purpose chamfer bit.
• The integrated ball-bearing guide eliminates the need to rely solely on a fence for edge positioning, which is especially valuable when routing curved or irregular workpiece profiles where a fence cannot maintain consistent contact.
• CMT's tungsten carbide (HW) construction means this bit is capable of handling not just solid hardwood and softwood but also engineered sheet goods like MDF and plywood - giving woodworkers and cabinetmakers one bit that transitions across common shop materials.
• The 1/2" shank provides a secure, low-vibration connection in both handheld router and router table setups, which is important when making long edge passes on beams, columns, or large panels where bit stability directly affects surface quality.
