Product Description
The CMT 811.254.11 Straight Bit Short Series is a precision-ground, double-fluted router bit engineered for clean, accurate straight cuts in a wide range of materials. Built from special fatigue-proof steel and micrograin carbide, this 1 in. diameter cutting tool is designed to handle demanding production workloads in plywood, solid wood, composites, and more. With a compact 2 in. total length and 1/4 in. shank, it fits standard handheld routers and router tables, making it a versatile choice for dadoes, grooves, mortising, and template routing applications where a shorter profile delivers better rigidity and control.
Key Features
- Micrograin carbide construction - provides exceptional hardness and edge retention under heavy, repeated use, reducing downtime from premature dulling during industrial-scale production.
- Special fatigue-proof steel body - resists stress and deformation from high-load cutting cycles, giving the bit a longer service life even in continuous routing applications.
- CMT Orange Shield non-stick P.T.F.E. coating - prevents resin, pitch, and other residue from bonding to the bit surface, keeping cuts cleaner and reducing the frequency of cleaning between passes.
- 2-flute (2-tooth) design - delivers efficient chip evacuation and a smooth cut finish in natural woods, plywood, and composite sheet goods.
- Right-hand rotation - compatible with the standard spindle direction of handheld routers, router tables, and CNC routing machines for straightforward drop-in use.
- Strict quality testing for balance and concentricity - each bit is individually verified to meet tight cutting tolerances, ensuring vibration-free performance and accurate, repeatable results.
- Short series profile at 2 in. total length - the compact overall length improves rigidity at the cutting edge, reducing deflection and chatter when making full-depth passes in thick stock.
Why This Product
- Built for production environments: The combination of micrograin carbide and fatigue-proof steel means this bit is rated for heavy, continuous workloads - not just occasional hobby use - making it well suited for shops routing plywood joinery, dadoes, and grooves at volume.
- Reduced maintenance between cuts: The orange P.T.F.E. non-stick coating actively resists pitch and resin adhesion, so the bit stays cleaner longer and spends more time cutting than being cleaned or cooled.
- More control in tight setups: The short series total length of 2 in. keeps the bit close to the collet, minimizing tool deflection and improving cut accuracy - a real advantage when routing template-guided profiles or precise joinery.
- Verified tolerances for consistent results: Because every bit passes strict balance and concentricity checks, routers paired with this bit run smoothly at operating speeds, protecting both the tool and the workpiece surface finish.

Frequently Asked Questions
What router collet size does this bit require?
This bit has a 1/4 in. shank and requires a router with a 1/4 in. collet. It is compatible with standard handheld routers and router tables that accept 1/4 in. tooling.
What is the maximum cutting depth this bit can achieve in a single pass?
The cutting height of this bit is 3/4 in., which represents the maximum depth of cut available. For best results in hardwoods and composites, multiple shallower passes are generally recommended rather than attempting the full 3/4 in. cutting height in a single pass.
What materials is this straight bit designed to cut?
This bit is suited for use in plywood, composites, and natural woods including solid hardwood and softwood. The micrograin carbide construction and fatigue-proof steel body are designed to handle both light work and heavy production volumes across these material types.
Why does this bit have an orange coating, and does it affect cutting performance?
The orange surface coating is CMT's P.T.F.E.-based non-stick finish. Its purpose is to prevent resin, pitch, and other residue from adhering to the bit during cutting. This helps maintain consistent cutting performance over time by keeping the flutes clear and reducing heat buildup from material buildup on the bit body.
