CMT Solid Carbide Straight Bit Short Series - 2mm Diameter, 1/4" Shank is a precision-ground routing bit engineered for clean, accurate straight cuts in tight, detail-oriented applications. Built from micrograin solid carbide and protected with CMT's trademark orange non-stick coating, this compact short-series bit delivers consistent performance when routing plywood, composites, natural wood, and plastic. Its small 2mm diameter makes it ideal for fine joinery, narrow grooves, and intricate template work where larger bits simply cannot reach.

Key Features

• Solid Carbide Micrograin Construction (HWM material grade) - the entire body is ground from micrograin carbide rather than just the tip, giving this bit exceptional rigidity and edge retention even under heavy, repeated workloads without chipping or deflecting.
• Fatigue-Proof Steel Body - the shank and body are manufactured from special fatigue-proof steel, meaning the bit resists stress fractures and body failure during prolonged production runs, extending usable tool life.
• Orange Non-Stick P.T.F.E. Coating - CMT's proprietary surface coating repels resin, pitch, and built-up residue, reducing heat buildup during cuts and making cleanup faster between passes.
• Single Flute (1 tooth) Geometry - the single-tooth design maximizes chip clearance in the cut path, which is especially valuable when routing narrow 2mm grooves where material evacuation is critical to cut quality.
• Right-Hand Rotation - designed for standard right-hand router spindle rotation, ensuring direct compatibility with handheld routers, router tables, and CNC routing machines without any modification.
• 1/4" Shank Diameter - the industry-common 1/4" shank fits the vast majority of router collets, making this bit straightforward to install in both hobbyist and industrial machines.
• Strict Quality Testing for Tolerance, Balance, and Concentricity - every bit is individually tested before leaving production, so buyers receive a tool that runs true and cuts to precise tolerance rather than one that vibrates or wanders off-line.

Why This Product

• Precision detail routing in confined spaces - the 2mm cutting diameter and short 5/32" cutting height keep the bit compact and rigid, reducing deflection when carving narrow dadoes, grooves, or mortises in hardwood, plywood, or MDF where a longer bit would flex.
• Production-ready durability - the combination of micrograin carbide construction and fatigue-proof steel is engineered specifically for industrial-scale production, not just occasional use, making this bit a reliable choice for shops cutting composites and natural woods in volume.
• Reduced maintenance between runs - the P.T.F.E. non-stick coating actively resists pitch and resin buildup on the bit surface, which means less time cleaning tooling and more time cutting, a measurable advantage in production environments.
• Verified dimensional accuracy out of the box - because each bit passes quality tests for concentricity and balance, routers and CNC machines experience less vibration and the finished cuts hold closer tolerances, reducing rework on fine joinery and template-routed parts.
