CMT 812.690.11 Straight Router Bit - Long Series, 3/4" Cutting Diameter, 1/2" Shank is a professional-grade routing tool engineered for deeper cuts and precise stock removal in demanding woodworking applications. Built with micrograin carbide cutters on a double-flute design, this long-series straight bit delivers smooth, accurate grooves, dadoes, and rabbets in hardwood, softwood, plywood, MDF, and composite materials. The extended cutting height makes it the go-to choice for panel joinery, template routing, and any operation where a standard-length bit simply cannot reach deep enough to complete the cut cleanly.

Key Features

• Micrograin Carbide Cutters on Special Fatigue Proof Steel Bodies - the combination of tough steel and fine-grain carbide edges handles heavy workloads without deflection, so the bit stays sharp and precise cut after cut.
• Double-Flute (2-Tooth) Geometry - two razor-sharp cutters remove material evenly from both sides of the cut path, producing a clean, smooth edge on the finished piece with minimal tearout.
• 1 1/2" Cutting Height in a Long-Series Profile - the extended flute length allows deeper passes in a single setup, reducing the need for multiple shallow plunge cuts and saving significant time on thicker stock.
• Exceptional Chip Ejection Design - the flute geometry clears waste material away from the cut zone continuously, keeping the cutting edge engaged with fresh material for a more consistent, cleaner result throughout the entire cut.
• CMT Orange Non-Stick PTFE Coating - the trademark orange protective surface prevents resin, pitch, and other residue from bonding to the bit body, reducing heat buildup and making cleanup fast so the bit performs like new longer.
• Right-Hand Rotation (RH) - compatible with all standard handheld routers, router tables, and CNC routing machines that use conventional right-hand spindle rotation.
• 1/2" Shank Diameter - the full 1/2" shank seats securely in 1/2" router collets, maximizing grip surface and minimizing vibration for a smoother cut and longer bearing life.

Why This Product

• Designed for deeper cuts without multiple setups - at 1 1/2" of cutting height and 3 1/4" total length, this long-series bit reaches depths that standard straight bits cannot, making it the right tool for full-depth dadoes, deep panel grooves, and thick-stock joinery in a single pass.
• Carbide quality that holds up under heavy production use - micrograin carbide cutters are built for even the heaviest workloads, meaning professional woodworkers and shop operators get consistent results across longer runs before needing to resharpen or replace the bit.
• The PTFE non-stick coating actively protects tool investment - by keeping pitch and resin from building up on the bit surface, the orange coating prevents the heat and drag that prematurely dull carbide edges, extending the usable life of the bit between sharpenings.
• Broad material compatibility makes it a versatile shop staple - the 3/4" diameter long-series straight bit works across solid hardwoods, softwoods, plywood, MDF, chipboard, laminates, melamine, and plastics, reducing the need for multiple specialized bits in a general woodworking or cabinetmaking operation.
