The CMT 195.506.11 Solid Carbide 3-Edge Spiral Bit with Chipbreaker is a professional-grade upcut spiral router bit engineered for high-demand cutting in solid wood, wood composites, plastic materials, and laminates. Built entirely from a special super-micrograin carbide formulation, this 1/2 in. diameter, 3-flute upcut bit combines a low-angle spiral geometry with chipbreaker technology to shear material cleanly, eject chips efficiently, and keep the tool running cooler at aggressive feed rates - making it a go-to choice for CNC routing, panel sizing, copying, and general routing applications where edge quality and tool longevity matter most.

Key Features

• Super-micrograin solid carbide construction - the special carbide formulation holds a keen cutting edge longer than standard carbide, reducing downtime for tool changes and increasing the number of resharpenings possible over the bit's service life.
• 3-flute (3R) cutting geometry with chipbreaker - three cutting edges combined with a chipbreaker break chips into smaller pieces for superior evacuation at high feed rates, preventing chip packing and reducing heat buildup in the cut zone.
• Low-angle upcut spiral design - specifically engineered to shear wood fibers cleanly rather than tear them, resulting in smoother finished surfaces and less material stress during routing passes.
• Efficient chip ejection - the upcut direction and low-angle spiral work together to pull chips up and out of the cut, keeping the flutes clear and allowing the tool to run cooler through extended production runs.
• 1/2 in. shank with 1 1/2 in. cutting height - the full 1 1/2 in. cutting height allows deep passes in a single setup, while the 1/2 in. shank provides maximum rigidity and minimizes deflection during aggressive routing operations.
• Right-hand (RH) rotation - compatible with the vast majority of standard CNC routers, router tables, and handheld routers, making this bit a versatile addition to any woodworking or fabrication shop.
• Broad material compatibility - rated for solid wood, wood composites, plastic materials, and laminates, this bit handles the full range of materials encountered in cabinetry, furniture production, sign making, and panel processing.

Why This Product

• Woodworkers and CNC operators who run production routing at high feed rates need a bit that manages chips aggressively - the 3-flute chipbreaker design addresses this directly by breaking chips small for clean, unobstructed evacuation rather than letting them pack and cause heat or surface defects.
• For shops routing a variety of substrates - from solid hardwood and softwood to laminates, melamine, and plastics - this bit's super-micrograin carbide and low-angle spiral geometry provide consistent, clean shearing cuts across all of them without switching tools.
• The combination of solid carbide construction and a cutting geometry designed to run cooler means edges stay sharp longer, reducing the cost and frequency of bit replacement and keeping production moving.
• At 3 1/2 in. total length with a 1 1/2 in. cutting height and a rigid 1/2 in. shank, this bit is proportioned for deep, stable cuts in panel sizing and copying work where deflection or chatter would otherwise compromise dimensional accuracy.
