CMT Solid Carbide Straight Bit Short Series - 1/4 in. Diameter, 1/4 in. Shank is a precision-ground, double-edge routing bit engineered for demanding production environments. Built from micrograin carbide and fatigue-proof steel, this short-series straight bit delivers clean, accurate cuts in plywood, natural wood, composites, and similar materials - whether you are working on a handheld router, a router table, or a CNC routing machine. The compact 2 in. overall length and 3/4 in. cutting height make it especially well-suited for dadoes, grooves, mortises, and template routing where rigidity and cutting accuracy are essential.

Key Features

• Solid micrograin carbide construction - the dense grain structure of the carbide body resists wear under heavy, continuous workloads, maintaining a sharp cutting edge far longer than standard steel bits.
• Fatigue-proof steel body - the shank and body are manufactured from special fatigue-proof steel that absorbs vibration and stress during high-production routing, reducing the risk of premature failure.
• 2-flute (2-tooth) geometry with right-hand rotation - the dual-edge cutting action clears chips efficiently while producing smooth, consistent surfaces in each pass through solid hardwood, softwood, plywood, and laminates.
• CMT orange non-stick PTFE coating - the proprietary orange surface treatment resists resin, pitch, and residue buildup, which reduces friction and heat at the cutting edge and helps extend tool life between cleanings.
• Short-series length design (2 in. total length) - the reduced overall length increases rigidity at the bit tip, minimizing deflection during deep or forceful cuts for tighter dimensional tolerances.
• Strict quality testing for tolerance, balance, and concentricity - every bit is individually tested so that it runs true in the collet, reducing runout and ensuring cuts stay on-dimension throughout the life of the bit.
• 1/4 in. shank - fits standard 1/4 in. collets found on a wide range of handheld routers and router tables, providing broad machine compatibility without adapters.

Why This Product

• Built for industrial-scale production - the micrograin carbide body and fatigue-proof steel construction are specifically rated for repeated, heavy-duty routing in plywood, composites, and natural woods, making this bit a reliable choice when uptime and consistency matter.
• Resists contamination that slows production - the PTFE non-stick coating actively repels resin and pitch, so the bit stays cleaner longer and requires less downtime for cleaning or replacement during extended production runs.
• Short-series geometry reduces deflection - for applications such as mortising, template routing, and plywood joinery where cut precision is critical, the shorter overall length keeps the bit stiffer and less prone to wandering under load.
• Individually quality-tested for balance and concentricity - each bit leaves the factory only after passing strict cutting tolerance checks, so you can trust dimensional accuracy from the first cut to the last, reducing scrap and rework.
