CMT Chamfer Bit with Bearing - 1 1/2" Diameter, 7/8" Cutting Height, 30 deg. Angle, 1/2" Shank is a precision router bit engineered for cutting clean, accurate bevels and chamfers on wood edges. Featuring a 30 deg. bevel angle and a carbide-tipped 2-flute design, this bit is well suited for decorative edge profiling, multi-sided box and container construction, and larger-scale architectural work on beams and columns. The integrated ball-bearing guide ensures consistent chamfer positioning pass after pass, making it a reliable choice for both handheld routers and router table setups.

Key Features

• 30 deg. Chamfer Angle - delivers a precise, repeatable bevel that aligns perfectly for multi-sided assemblies such as boxes, frames, and decorative containers, as well as architectural elements like beams and columns.
• 1 1/2" Cutting Diameter - provides broad material contact per pass, reducing the number of passes needed for larger chamfering jobs and increasing productivity on edge work.
• 7/8" Cutting Height - accommodates a generous depth of cut, allowing the bit to work through thicker stock and produce full, consistent bevels without repositioning.
• HW (Carbide) Cutting Material - hard-wearing tungsten carbide edges stay sharp longer through hardwood, softwood, and composite materials, reducing downtime for bit changes.
• 2-Flute (2-Tooth) Design - dual cutting edges promote smooth chip evacuation and a cleaner finish on the chamfered surface, minimizing tearout and sanding time.
• Ball-Bearing Pilot Guide - rides along the workpiece edge to maintain a uniform chamfer position, eliminating the need for fences or guides on most edge-profiling tasks.
• 1/2" Shank - fits standard 1/2" router collets found on full-size handheld routers and router tables, providing a secure, vibration-reducing grip for accurate cuts.
• Right-Hand Rotation (RH) - compatible with the standard direction of virtually all routers, ensuring proper cutting action and chip clearance without modification.

Why This Product

• The 30 deg. angle is specifically suited for creating perfectly aligned mitered joints on multi-sided containers and decorative boxes, where consistent angular accuracy is critical to a tight, gap-free assembly.
• The built-in ball-bearing guide removes the guesswork from positioning - just register the bearing against the workpiece edge and the bit self-indexes the chamfer depth, making it practical for repetitive production runs and one-off projects alike.
• With a 1 1/2" cutting diameter and 7/8" cutting height, this bit handles both fine furniture edge work and larger-scale applications such as chamfering beams and columns - versatility that reduces the number of specialized bits needed in a shop.
• The 2-flute carbide construction produces a finished bevel surface that requires minimal cleanup, saving sanding and finishing time on hardwoods, softwoods, and engineered wood products.
