The CMT 811.100.11 Straight Bit Short Series is a precision-ground, double-edged carbide router bit engineered for clean, accurate straight cuts in a wide range of woodworking and production applications. With a 10mm cutting diameter, a 3/4 in. cutting height, and a compact 1 7/8 in. total length, this short-series bit is built for situations where rigidity and control matter - minimizing deflection and chatter during dadoes, grooves, mortises, and rabbet cuts. Designed for use with 1/4 in. shank routers, it performs reliably in handheld routers, router tables, and CNC routing machines, making it a versatile tool for both craftsmen and industrial production environments working with plywood, composites, and natural woods.

Key Features

• Micrograin Carbide Cutting Edges (HW Material Grade) - delivers superior hardness and wear resistance compared to standard carbide, extending cutting life even under heavy production workloads with demanding materials like composites and hardwoods.
• Fatigue-Proof Steel Body - the bit shank and body are manufactured from special fatigue-proof steel, reducing the risk of stress fractures or body failure during prolonged or high-feed-rate routing operations.
• CMT Orange Non-Stick PTFE Coating - the trademark orange surface treatment prevents resin, pitch, and other residue from adhering to the bit, reducing heat buildup, protecting against corrosion, and making cleanup faster between cuts.
• 2-Flute (2-Tooth) Design - dual cutting edges provide balanced chip evacuation and smooth surface finishes on dadoes, grooves, and mortises in solid wood, plywood, MDF, and laminates.
• Short Series Profile - the compact 1 7/8 in. total length minimizes overhang and maximizes rigidity at the collet, reducing vibration and improving cut accuracy compared to longer-series equivalents.
• Right-Hand Rotation - compatible with standard right-hand collet routers and CNC spindles, ensuring correct chip ejection direction and safe operation on conventional routing equipment.
• Strict Quality Testing for Tolerance, Balance, and Concentricity - every bit is individually tested to verify cutting tolerance, rotational balance, and concentricity, which means smoother cuts, longer bearing life on CNC machines, and predictable performance on every pass.

Why This Product

• The short-series design is the right choice when routing shallow dadoes, grooves, or mortises where a long bit would introduce unnecessary flex - the compact length keeps the cutting edge closer to the collet for maximum stability and precision.
• The combination of micrograin carbide and fatigue-proof steel construction means this bit can withstand the demands of industrial-scale production runs, not just occasional hobby use - making it a cost-effective choice for shops processing plywood, composites, or hardwood in volume.
• The PTFE non-stick coating actively reduces resin and pitch adhesion during cuts in sticky or resinous woods, helping maintain consistent cutting performance across longer production runs without frequent stops to clean the bit.
• With a 1/4 in. shank and right-hand rotation, this bit fits the widest range of compact routers, router tables, and entry-level CNC machines, making it accessible for both small shop setups and larger production environments without requiring special tooling adapters.
