The CMT 811.140.11 Straight Bit Short Series is a precision-ground, double-fluted routing bit built for demanding production environments and everyday woodworking alike. Designed to cut a clean 14mm diameter channel with a 3/4 in. cutting height, this compact short-series bit excels at dadoes, grooves, mortises, and rabbet cuts in solid hardwood, softwood, plywood, composites, and a wide range of other materials. Its 1/4 in. shank makes it compatible with handheld routers, router tables, and CNC routing machines, giving woodworkers and fabricators a versatile tool for accurate straight cuts across production and shop settings.

Key Features

• Micrograin Carbide Cutting Edges (HW Material Grade) - harder, denser carbide stays sharper longer under heavy workloads, reducing downtime and the frequency of bit replacements during high-volume production runs.
• Fatigue-Proof Steel Body - the specially formulated steel shank and body resist stress fractures under continuous use, delivering consistent, safe performance even when routing dense hardwoods or composites.
• CMT Orange Shield Non-Stick P.T.F.E. Coating - the trademark orange coating actively repels resin, pitch, and other residue buildup, keeping the bit cleaner between passes, reducing heat accumulation, and extending overall tool life.
• 2-Flute (Double-Edged) Configuration - two cutting edges provide a balanced cut with smooth chip evacuation, producing cleaner groove walls and reducing tear-out in plywood, MDF, and natural wood.
• Short-Series Profile (2 in. Total Length) - the compact overall length improves rigidity and reduces vibration compared to longer bit profiles, resulting in more precise, chatter-free cuts in shallow routing applications.
• Right-Hand Rotation - standard RH rotation is compatible with the vast majority of routers and CNC spindles, ensuring straightforward drop-in use without any spindle direction adjustments.
• Strict Quality Testing for Tolerance, Balance, and Concentricity - every bit passes rigorous factory inspection to guarantee it runs true, minimizing runout and producing repeatable, on-dimension cuts across the entire job.

Why This Product

• Built for production-scale demands - the combination of micrograin carbide, fatigue-proof steel, and P.T.F.E. coating means this bit is engineered to handle continuous routing in plywood joinery, composite panel work, and natural wood applications without premature wear or performance drop-off.
• Short-series design reduces deflection and chatter - at 2 in. total length with a 3/4 in. cutting height, this bit is optimized for shallow dado, groove, and mortise work where rigidity directly translates to tighter tolerances and cleaner cut walls.
• Non-stick coating cuts cleanup time - the orange P.T.F.E. surface treatment prevents resin and pitch from bonding to the carbide, meaning less time cleaning bits between operations and more consistent cutting performance throughout the workday.
• Verified concentricity for CNC and handheld use - quality-tested balance and concentricity standards make this bit a reliable choice for both handheld router work and CNC routing applications where runout directly affects finished part quality.
