CMT Solid Carbide Upcut Spiral Bit - 3/16" Diameter is a precision-ground, single-flute router bit engineered from a special super-micrograin carbide formulation that produces and holds a keen cutting edge through demanding routing applications. Designed with a low-angle upcut spiral geometry, this bit shears wood cleanly while ejecting chips upward for efficient chip evacuation - keeping your work area clear and your cuts precise. Whether you are running a CNC machine, routing solid hardwood, or working with plastic materials and laminates, this bit delivers clean, repeatable results with less heat buildup and longer-lasting edges.

Key Features

• Super-micrograin carbide construction - produces and holds a keen cutting edge longer than standard carbide, allowing more resharpenings and extended tool life between replacements.
• Low-angle upcut spiral geometry - designed specifically to shear wood cleanly and provide efficient chip ejection, so the tool runs cooler and cutting edges last longer during demanding routing sessions.
• Single-flute (1-tooth) design - maximizes chip clearance space on smaller-diameter bits, reducing recutting and heat for cleaner cuts in wood composites, plastics, and laminates.
• Right-hand rotation - compatible with standard router table and CNC spindle configurations, making this bit a straightforward drop-in for most setups.
• 1/4" shank diameter - fits a wide range of handheld routers, router tables, and CNC collets, giving this compact 3/16" cutting diameter bit broad machine compatibility.
• 2" total length with 5/8" cutting height - provides sufficient reach for panel sizing, copying, and deep pocket work without sacrificing rigidity in the cut.

Why This Product

• The special super-micrograin carbide formulation means the cutting edge stays sharper longer - reducing downtime for tool changes and lowering cost-per-cut on high-volume routing work in solid wood, wood composites, and plastic materials.
• The low-angle spiral is purpose-built for clean shearing action, not just chip removal - making this bit a strong choice when surface finish quality matters on solid hardwood, laminates, or melamine panels.
• At 3/16" cutting diameter with a 1/4" shank, this bit fills a precise niche for detail routing, narrow grooves, and fine profile work where larger-diameter bits cannot reach without overcutting.
• Upcut chip ejection keeps the flute clear during continuous passes, helping the bit run cooler - a practical advantage when routing plastics or dense laminates that can trap heat and cause edge degradation.
