Product Description
CMT Straight Bit Short Series - 14mm, 1/4 in. Shank by CMT is a compact, two-flute router bit engineered for precise straight cutting in solid hardwood, softwood, plywood, composites, and other sheet materials. With a 3/4 in. cutting diameter and a 3/4 in. cutting height packed into a 2-1/4 in. overall length, this short-series bit delivers tight clearances and excellent control for dadoes, grooves, rabbets, mortising, and template routing tasks on handheld routers, router tables, and CNC routing machines alike.
Key Features
- Micrograin Carbide Cutting Edges - provides superior hardness and edge retention, so the bit stays sharp longer through demanding production runs in plywood, composites, and natural woods.
- Fatigue-Proof Steel Body - the body is constructed from special fatigue-proof steel that resists flexing and stress under heavy workloads, reducing the risk of bit failure during extended use.
- CMT Orange Non-Stick PTFE Coating - the trademark orange protective surface shields the bit from resin, pitch, and residue buildup, reduces heat accumulation, and helps maintain cutting performance over time.
- Two-Flute Design (2 teeth) - dual cutting edges balance chip removal with a smooth finish, making this bit suitable for both production-speed routing and clean finished cuts.
- Right-Hand Rotation - compatible with standard router spindle direction, ensuring straightforward installation and safe operation without adapters.
- Strict Quality Testing - every bit is individually tested for cutting tolerance, balance, and concentricity, so you can trust dimensional accuracy and vibration-free performance straight out of the box.
- Short Series Form Factor - the compact 2-1/4 in. total length reduces deflection and improves rigidity, which translates to cleaner cuts and better accuracy compared to longer bit profiles.
- 1/4 in. Shank - fits a wide range of compact and full-size routers with 1/4 in. collets, offering broad machine compatibility for shops of all sizes.
Why This Product
- The short-series body length minimizes bit deflection during aggressive passes, making it a reliable choice for production environments where dimensional consistency across repeated cuts is essential.
- The PTFE non-stick coating actively resists resin and pitch accumulation - a practical advantage when routing sticky materials like pine, composite panels, or melamine where bit fouling is a common productivity problem.
- Micrograin carbide construction combined with individual quality testing means each bit meets tight concentricity and balance standards, reducing vibration that can cause chatter marks or inaccurate grooves.
- With a 3/4 in. diameter and 3/4 in. cutting height, this bit handles full-depth dado and groove cuts in standard 3/4 in. sheet goods in a single pass, streamlining joinery and case construction workflows.

Frequently Asked Questions
What materials can this straight router bit cut through?
This bit is designed for use in a variety of materials including solid hardwood, softwood, plywood, composites, and natural wood panels. The micrograin carbide cutting edges and fatigue-proof steel body are built to handle even heavy production workloads across these material types.
Why choose a short-series bit over a standard-length straight bit?
The short-series form factor reduces the overall overhang of the bit from the collet, which minimizes deflection and improves rigidity during cutting. This results in more accurate cuts with less vibration - particularly useful when routing dadoes, grooves, or mortises where dimensional precision matters.
What is the purpose of the orange PTFE coating on this bit?
The non-stick PTFE coating on the body and shank helps prevent resin, pitch, and other cutting residue from adhering to the bit surface. This keeps the bit cleaner during use, reduces heat buildup, and protects against corrosion - all of which contribute to a longer working life for the bit.
Is this bit compatible with CNC routers as well as handheld routers?
Yes. With its 1/4 in. shank and right-hand rotation, this bit is compatible with handheld routers, router tables, and CNC routing machines that accept a 1/4 in. collet. The strict quality testing for balance and concentricity makes it particularly well-suited to CNC applications where runout tolerance is critical.
