The CMT 811.065.11 Solid Carbide Straight Bit Short Series is a precision-engineered routing bit designed for professionals and serious woodworkers who demand clean, accurate cuts in demanding production environments. Built from micrograin solid carbide and housed in a 1/4 in. shank format, this short-series straight bit delivers consistent performance across plywood, composites, natural hardwoods, and softwoods. Whether you are cutting dadoes, grooves, or mortises on a router table or CNC machine, this two-flute cutter offers the rigidity and edge retention needed to handle heavy production workloads without compromise.

Key Features

• Solid Carbide Micrograin Construction - made from micrograin carbide for exceptional edge retention and durability, allowing the bit to maintain sharp, precise cuts even under continuous industrial use.
• Fatigue-Proof Steel Body - the body is formed from special fatigue-proof steel that resists stress and deformation under heavy workloads, extending the service life of the bit in high-volume production settings.
• CMT Orange Non-Stick P.T.F.E. Coating - the trademark orange P.T.F.E. surface treatment prevents resin, pitch, and other residue from adhering to the bit, reducing heat buildup and keeping the cutting edge cleaner for longer between cleanings.
• Two-Flute Design - dual cutting edges deliver smooth, balanced material removal for cleaner cut surfaces on plywood, natural wood, and composite materials.
• Short-Series Profile - the compact 2-1/4 in. total length and 3/4 in. cutting height improve rigidity and reduce deflection, making this bit especially effective for shallow dados, grooves, and template routing applications where precision matters most.
• Strict Quality and Concentricity Testing - every bit is subject to rigorous quality controls for cutting tolerance, balance, and concentricity, so you get consistent, repeatable results from the first pass to the last.
• 1/4 in. Shank Compatibility - fits standard 1/4 in. collets on handheld routers, router tables, and CNC routing machines, making this bit a versatile addition to a wide range of setups.

Why This Product

• The micrograin solid carbide construction combined with fatigue-proof steel resists material failure during heavy production runs - making this bit a reliable choice when downtime from broken or dulled tooling is not an option.
• The P.T.F.E. non-stick orange coating actively reduces pitch and resin accumulation during cuts in natural hardwoods, softwoods, and composite panels, meaning less frequent cleaning stops and more consistent cut quality across a full production session.
• The short-series format keeps the bit stiff and centered during demanding cuts - especially valuable for tight tolerance work like dado joinery in plywood or mortising in solid hardwood where even slight deflection creates a poor fit.
• Backed by strict balance and concentricity testing at the factory level, this bit is suited to CNC routing applications where runout and vibration directly affect finished part quality and machine wear.
