CMT Solid Carbide Straight Bit - Long Series, 15/64" Diameter, 1/4" Shank by CMT is engineered for woodworkers who need to rout deep grooves, dadoes, and precise channels in a single pass. With a full 1" cutting height and 2 3/8" total length, this long-series router bit reaches deeper than standard straight bits, making it a reliable choice for template routing, panel joinery, and dado work in hardwood, softwood, plywood, MDF, and more. The 15/64" cutting diameter delivers a clean, accurate slot width ideal for specialized joinery and precision woodworking applications.

Key Features

• Solid Micrograin Carbide Construction - micrograin carbide provides exceptional hardness and edge retention, so the bit maintains a sharp, precise cut even through the heaviest workloads without premature dulling.
• Long-Series Design with 1" Cutting Height - the extended cutting zone lets you rout deep grooves and dadoes in thick stock that shorter bits simply cannot reach, reducing the need for multiple passes.
• Double-Faced Razor-Sharp Cutters - two cutting faces made from special Fatigue Proof steel and micrograin carbide work together to produce smooth, clean edges on finished pieces, minimizing tearout and sanding time.
• Exceptional Chip Ejection - the flute geometry actively clears chips away from the cutting zone, keeping the cut path clean and allowing more consistent material removal throughout the full depth of the cut.
• CMT Orange Shield Non-Stick PTFE Coating - the trademark orange PTFE coating on the bit surface resists resin, pitch, and residue buildup, which reduces heat generation, protects against corrosion, and extends the working life of the bit.
• Right-Hand Rotation - compatible with standard handheld routers, router tables, and CNC routing machines without any adapter or modification required.
• 1/4" Shank Diameter - fits the most common router collet size, giving this long-series bit wide compatibility across hobbyist and professional routers alike.

Why This Product

• The 1" cutting height on a 15/64" diameter bit gives woodworkers access to a precise, narrow slot at depth - a combination that is difficult to achieve with standard-length straight bits and that handles demanding dado and groove work in thicker panels.
• The two-flute solid carbide design handles heavy material removal while still delivering a smooth, finished edge, which means less time cleaning up cuts with a chisel or sandpaper after routing.
• The orange PTFE non-stick coating directly addresses one of the most common causes of bit degradation - resin and pitch buildup - keeping the cutting edges cleaner for longer service life across hardwood, softwood, MDF, plastic, and laminate materials.
• At 2 3/8" total length with a 1/4" shank, this bit fits a wide range of standard routers and router table setups, making it a practical long-series option without requiring a specialized machine or collet.
