The CMT 811.160.11 Straight Bit Short Series is a precision-ground, 16mm diameter router bit engineered for clean, accurate straight cuts in a wide range of wood-based and composite materials. Designed for both handheld routers and router table setups, this compact short-series bit delivers consistent performance in dadoing, grooving, mortising, and template routing applications. Built from micrograin carbide bonded to a fatigue-proof steel body, it is equally at home in light workshop use or demanding industrial-scale production environments.

Key Features

• Micrograin Carbide Cutting Edges (HW Material Grade) - extremely fine carbide grain structure maintains a sharper edge longer, reducing tear-out in natural wood, plywood, and composite panels and extending time between sharpenings.
• Special Fatigue-Proof Steel Body - the body resists flex and stress fracture under heavy, repeated workloads, keeping the bit true and safe even during extended production runs.
• CMT Orange Non-Stick P.T.F.E. Coating - the trademark orange surface coating prevents resin, pitch, and other residue from sticking to the bit, reducing heat buildup and keeping cuts smooth without constant cleaning stops.
• 2-Flute Double-Edged Cutter Design - two cutting edges balance chip evacuation and feed rate, delivering a cleaner finished surface in a single pass through solid hardwood, MDF, chipboard, laminates, and melamine.
• Right-Hand Rotation (RH) - compatible with the standard right-hand spindle direction of conventional handheld routers, router tables, and CNC routing machines - no adapter or special setup required.
• 1/4 in. Shank - fits a wide range of compact routers and standard router table collets, making this bit highly versatile across common workshop and production tool configurations.
• Short Series Format (2-1/4 in. Total Length) - the reduced overall length increases rigidity and minimizes bit deflection, producing tighter dimensional tolerances in grooves and dadoes.
• Strict Quality Tolerance Testing - every bit is individually tested for cutting tolerance, rotational balance, and concentricity, ensuring repeatable, predictable results cut after cut.

Why This Product

• The short-series body length keeps the bit as rigid as possible during the cut, which directly reduces chatter and deflection - ideal when precise groove width and flat bottom quality matter, such as in plywood joinery and cabinetry dado work.
• The P.T.F.E. non-stick orange coating means less downtime cleaning pitch and resin from the bit during production runs, which translates directly to more efficient throughput when routing natural woods, laminates, or melamine panels.
• Micrograin carbide construction holds a sharper edge over more cuts than standard carbide grades, making this bit a practical choice for shops routing abrasive composite materials like MDF and chipboard on a regular basis.
• With a 1/4 in. shank and right-hand rotation, this bit is broadly compatible with compact handheld routers and router tables alike - one bit that moves easily between machines without requiring a dedicated collet set.
