Product Description
CMT 811.182.11 Straight Bit Short Series - 23/32" Diameter, 1/4" Shank is a compact, double-edged router bit engineered by CMT for precise straight cuts in plywood, composites, and natural woods. Designed for both handheld routers and router table setups, this short-series straight bit delivers clean dadoes, grooves, rabbets, and mortises with consistent accuracy. Its compact overall length makes it especially well-suited for template routing and CNC routing applications where rigidity and cutting precision matter most.
Key Features
- Micrograin Carbide Cutting Edge (HW Material) - a harder, denser carbide grade that stays sharp longer under heavy production workloads, reducing downtime and replacement frequency.
- Fatigue-Proof Steel Body - the bit body is made from special fatigue-proof steel, which means it resists stress fractures and deformation even during extended, high-demand routing sessions.
- CMT Orange Shield Non-Stick Coating - the proprietary orange P.T.F.E. coating repels resin, pitch, and other residue so the bit runs cooler, stays cleaner, and maintains cutting efficiency between uses.
- 2-Flute Design - two cutting edges provide a balanced cut with smooth chip evacuation, reducing tear-out in plywood, MDF, chipboard, laminates, and solid wood.
- Right-Hand Rotation - compatible with the standard rotation direction of handheld routers, router tables, and CNC routing machines for straightforward, drop-in use.
- Strict Quality Testing for Balance and Concentricity - every bit is individually tested for cutting tolerance, balance, and concentricity, so you get consistent, vibration-free performance right out of the box.
- Short Series Profile - the compact 2 1/4" total length and 1" cutting height minimize deflection and chatter, making it ideal for demanding production cuts that require tight dimensional control.
Why This Product
- The short-series design reduces bit deflection during cuts, making this an excellent choice for high-precision joinery, dado work, and template routing where dimensional accuracy is critical.
- The combination of micrograin carbide and fatigue-proof steel construction allows this bit to handle industrial-scale production volumes across a wide range of sheet goods and solid wood species without premature wear.
- The P.T.F.E. non-stick coating minimizes pitch and resin adhesion, which means less cleaning, less friction heat buildup, and longer intervals between sharpenings - a practical advantage in busy shop environments.
- With a 1/4" shank, this bit is compatible with a wide range of standard handheld routers, compact routers, and router tables, offering versatility across job sites and woodshop setups without requiring a collet adapter.

Frequently Asked Questions
What routers is this bit compatible with?
This bit has a 1/4" shank, which fits standard 1/4" collets found on handheld routers, compact routers, and router tables. It is also suitable for use on CNC routing machines equipped with a compatible 1/4" collet.
What materials can this straight bit cut?
This bit is designed to cut a variety of materials including solid hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastic. The micrograin carbide construction handles the full range of these materials at production scale.
What is the purpose of the orange non-stick coating on this bit?
The orange P.T.F.E. coating is CMT's proprietary surface treatment that helps prevent resin, pitch, and other residue from sticking to the bit. This keeps the cutting edges cleaner during use, reduces heat from friction, and helps protect the tool body against corrosion, which extends the overall service life of the bit.
Why choose a short-series straight bit instead of a standard-length straight bit?
Short-series bits have a reduced total length - in this case 2 1/4" overall with a 1" cutting height - which minimizes lateral deflection and vibration during the cut. This makes them a preferred choice when tight cutting tolerances, consistent groove depths, and clean edge quality are required, particularly in production environments or when working with plywood joinery and composites.
