Product Description
The CMT 811.060.11 Solid Carbide Straight Bit Short Series is a precision-ground, two-flute router bit engineered for clean, accurate straight cuts in plywood, composites, and natural woods. Built from micrograin solid carbide and mounted on a 1/4 in. shank, this short-series bit delivers the rigidity and cutting performance demanded by both professional woodworkers and industrial CNC routing applications. With a 15/64 in. cutting diameter and a compact 2 in. overall length, it is optimized for routing dadoes, grooves, and mortises where reduced bit deflection and tight tolerances are critical.
Key Features
- Micrograin Solid Carbide Construction - the micrograin carbide material resists wear and maintains a sharper edge longer than standard carbide, reducing the need for frequent bit changes during high-volume production runs.
- Fatigue-Proof Steel Body - the special fatigue-proof steel shank withstands heavy workloads and repeated routing passes without flexing, helping preserve cut accuracy over time.
- CMT Orange Non-Stick P.T.F.E. Coating - the proprietary orange coating prevents resin, pitch, and other residue from bonding to the bit surface, keeping the cutting edges cleaner and reducing heat buildup during extended use.
- 2-Flute Design (Right-Hand Rotation) - the double-edged cutting geometry with right-hand rotation produces smooth chip evacuation and consistent surface finishes in both hardwood and sheet goods.
- Short-Series Profile (2 in. Total Length) - the compact body minimizes vibration and deflection, which translates directly into tighter tolerances and improved cut quality compared to longer bit profiles at the same diameter.
- Strict Quality Testing for Balance and Concentricity - every bit is individually tested for cutting tolerance, balance, and concentricity, ensuring consistent, repeatable performance in production environments.
Why This Product
- The 15/64 in. diameter fills a precise sizing gap between standard 1/4 in. and common fractional sizes, making this bit the right choice when your joinery or mortise application demands an exact fit rather than a close approximation.
- The short-series body length reduces bit deflection on deep or repeated passes through dense hardwoods, plywood, and composites - a practical advantage when straight-wall accuracy matters in dado and groove work.
- The P.T.F.E. non-stick coating actively reduces pitch and resin accumulation, meaning less time cleaning bits between operations and more consistent cutting performance across a full production shift.
- Solid micrograin carbide construction paired with rigorous balance and concentricity testing makes this bit suitable for both handheld routers and CNC routing machines where runout tolerance is critical to finished part quality.

Frequently Asked Questions
What materials can this solid carbide straight bit cut?
This bit is designed for use in a variety of materials including plywood, composites, and natural woods such as solid hardwood and softwood. The micrograin solid carbide construction gives it the wear resistance needed to maintain clean edges across these materials in both light and heavy production workloads.
Can this bit be used in a CNC routing machine, or is it limited to handheld routers?
This bit is suitable for handheld routers, router tables, and CNC routing machines. The short-series body length reduces deflection and vibration, and the strict balance and concentricity testing performed on every bit makes it particularly well-suited for CNC applications where runout tolerance is important.
Why does the bit have a P.T.F.E. orange coating, and does it affect cutting performance?
The orange P.T.F.E. non-stick coating is CMT's trademark protective surface treatment. It prevents resin, pitch, and other residue from adhering to the bit during cutting, which helps keep the cutting edges cleaner, reduces heat buildup, and extends the usable life of the bit between cleanings.
What is the difference between a short-series straight bit and a standard-length straight bit?
A short-series bit has a reduced total body length - in this case 2 in. overall - compared to standard-length equivalents at the same diameter. The shorter profile increases rigidity, reduces bit deflection during heavy cuts, and improves cutting accuracy. This makes short-series bits especially useful when routing dense materials or when tight wall tolerances are required in dadoes and mortises.
