The CMT 812.150.11 Straight Bit Long Series is a precision-ground, long-reach routing tool engineered for woodworkers and fabricators who demand clean, repeatable results on deep straight cuts, dadoes, grooves, and panel joinery. With a 15mm cutting diameter and a 1 1/4 in. cutting height on a 1/4 in. shank, this two-flute carbide router bit delivers the extended reach needed to rout through thicker stock in a single pass - making it equally well-suited for handheld router work, router table setups, and CNC routing applications. Built from micrograin carbide and special Fatigue Proof steel, it is designed to maintain a sharp, smooth edge through even the heaviest production workloads.

Key Features

• Micrograin Carbide Cutters on Fatigue Proof Steel Body - razor-sharp, double-faced cutting edges resist dulling under heavy workloads, so you get a smooth, precise cut on every pass through solid hardwood, plywood, MDF, laminates, melamine, and plastics.
• Long Series Design with 1 1/4 in. Cutting Height - the extended flute length allows deeper routing passes that standard-length bits cannot achieve, reducing the number of passes required on thick panels and solid stock.
• Two-Flute (2-Tooth) Configuration - the dual-cutter geometry produces a clean finished edge on both faces of the workpiece, minimizing tearout and reducing sanding time on completed pieces.
• Exceptional Chip Ejection - optimized flute geometry clears waste material efficiently during cutting, allowing cleaner and more constant contact with the material for consistent groove depth and wall quality.
• CMT Orange Shield Non-Stick PTFE Coating - the trademark orange PTFE surface treatment on the bit body prevents resin, pitch, and other residue from bonding to the tool, reducing heat buildup, protecting against corrosion, and extending overall tool life between cleanings.
• Right-Hand Rotation - compatible with the standard rotation direction of virtually all handheld routers, router tables, and CNC spindles, so no special setup is required.
• 1/4 in. Shank - fits the most widely available router collets, making this bit accessible for a broad range of machines from compact trim routers to full-size table routers.

Why This Product

• The 1 1/4 in. cutting height gives you genuine deep-cut capability in a single pass - ideal for routing dadoes, housing joints, and full-depth grooves in thick stock where shorter bits fall short.
• The double-faced micrograin carbide cutters produce a finished edge that is clean on both sides of the cut, reducing secondary processing time on visible joinery and panel work.
• The non-stick PTFE coating actively resists resin and pitch accumulation, which means the bit stays sharper longer and requires less frequent cleaning when routing resinous woods, laminates, and melamine-faced boards.
• With a 2 5/8 in. total length and a standard 1/4 in. shank, this bit bridges the gap between compact trim-router bits and full 1/2 in. shank production tooling - giving smaller machines access to long-series cutting depth without requiring a collet upgrade.
