The CMT 811.627.11 Straight Bit Short Series is a precision-engineered, double-edged router bit designed for clean, accurate straight cuts in a wide range of woodworking and production routing applications. Built from special fatigue-proof steel and micrograin carbide, this 1/2 in. shank, 1/2 in. diameter cutter is an ideal choice for dadoes, grooves, mortising, and template routing in solid hardwood, plywood, composites, and more. Whether used in a handheld router, router table, or CNC routing machine, this short-series straight bit delivers the balance, concentricity, and cutting tolerance demanded by both professional shops and industrial-scale operations.

Key Features

• CMT Orange Shield Non-Stick Coating - the trademark orange P.T.F.E. surface treatment prevents resin, pitch, and residue buildup on the bit, reducing friction and heat during routing so the bit stays cleaner and lasts longer between sharpenings.
• Micrograin Carbide Cutting Edges - a denser, finer carbide grain structure resists chipping and wear under heavy production loads, delivering consistently clean cuts in hardwoods, plywood, MDF, and composites over an extended service life.
• Fatigue-Proof Steel Body - the bit body is manufactured from special fatigue-proof steel engineered to withstand the mechanical stress of repetitive, high-volume routing without risk of material failure or structural fatigue.
• 2-Flute Design with Right-Hand Rotation - the double-edged geometry balances chip evacuation and surface finish, producing smooth, accurate cuts with each pass in standard right-hand router configurations.
• Strict Quality Testing for Tolerance, Balance, and Concentricity - every bit is individually tested to guarantee that cutting tolerances, rotational balance, and concentricity meet precise standards, reducing vibration and improving cut quality.
• Short-Series Profile - the compact 2-5/8 in. total length with a 1 in. cutting height improves rigidity and reduces deflection during routing, making it especially well-suited for plywood joinery, dadoes, and controlled depth work.

Why This Product

• The micrograin carbide construction combined with fatigue-proof steel makes this bit capable of handling the heaviest production workloads without premature wear - a practical choice for shops routing hardwoods, composites, and laminates on a daily basis.
• The P.T.F.E. non-stick coating directly addresses one of the most common productivity problems in production routing - resin and pitch accumulation - keeping the bit performing at full efficiency with less frequent cleaning.
• The short-series geometry (1 in. cutting height, 2-5/8 in. total length) provides a stiffer, more stable cutting profile compared to longer bit configurations, reducing chatter and improving accuracy in dadoes, grooves, and plywood joinery.
• With a 1/2 in. shank and compatibility with handheld routers, router tables, and CNC routing machines, this bit adapts to multiple production setups without requiring a dedicated machine or special tooling.
