The CMT 811.150.11 Straight Bit Short Series is a 15mm diameter, two-flute carbide router bit designed for precise straight cutting in solid wood, plywood, composites, and a wide range of engineered wood products. Built for both handheld routers and router table use, this short-series straight bit delivers the tight tolerances and reliable performance that production woodworking and cabinetry applications demand. Its compact overall length makes it especially well-suited for dadoes, grooves, rabbets, mortising, and template routing where rigidity and accuracy are critical.

Key Features

• Micrograin Carbide Cutting Edges - the two cutting flutes are ground from high-density micrograin carbide, providing longer edge life and cleaner cuts through hardwoods, softwoods, plywood, and composites compared to standard carbide grades.
• FATIGUE-PROOF Steel Body - the body is machined from special fatigue-proof steel that resists stress fractures under heavy workloads, keeping the bit running true and safe even during demanding production runs.
• CMT Orange Shield Non-Stick Coating - the proprietary P.T.F.E. surface treatment prevents resin, pitch, and other residue from building up on the bit, reducing heat generation and making cleanup faster while extending overall tool life.
• Two-Flute (2-tooth) Configuration - the double-edged design balances cutting speed with chip clearance, making it effective across plywood joinery, natural wood dadoes, and composite panel routing without clogging.
• 1/4 in. Shank - fits the widest range of compact and full-size handheld routers as well as router tables, offering broad compatibility without the need for a collet adapter.
• Short Series Profile (2-1/4 in. total length) - the reduced overall length improves rigidity at the router collet, minimizing deflection and chatter for truer, more accurate cuts in grooves and mortises.
• Strict Quality Testing for Balance and Concentricity - every bit is tested to verify cutting tolerance, balance, and concentricity before leaving the factory, which translates to smooth, vibration-free operation and consistent cut quality.
• Right-Hand Rotation - standard RH rotation is compatible with all conventional routers, requiring no special setup or configuration.

Why This Product

• The 15mm cutting diameter is a precise metric size well suited to machining standard dado widths and mortises in plywood, MDF, and solid wood - eliminating the need for multiple passes to reach a target dimension.
• The short-series geometry (3/4 in. cutting height, 2-1/4 in. total length) keeps the bit close to the collet for maximum rigidity, which is especially valuable when routing hardwood or dense composites where longer bits are prone to deflection.
• The orange P.T.F.E. non-stick coating actively reduces resin and pitch buildup during production runs in melamine, laminates, and natural woods - cutting downtime for mid-shift cleaning and keeping the cutting edges performing at their best longer.
• With micrograin carbide cutters and a fatigue-proof steel body, this bit is built to handle the repetitive, high-volume demands of industrial-scale production as well as the precision requirements of fine woodworking and cabinet joinery.
