Product Description
CMT Straight Router Bit with Insert Knives - 1/2 in. Diameter, 1/2 in. Shank is a precision-engineered routing tool designed for clean, accurate straight cuts across a wide range of materials. Built with a replaceable insert knife system, this bit delivers long-lasting performance in both hand router and router table applications. Whether you are cutting dadoes, grooves, or rabbets in hardwood, softwood, plywood, MDF, chipboard, laminates, or plastics, this straight bit offers the cutting depth and rigidity needed for demanding woodworking tasks.
Key Features
- Replaceable Hardwood (HW) Insert Knives - Two-sided reversible knives can be flipped to expose a fresh cutting edge, effectively doubling usable tool life and reducing the cost per cut over time.
- TORX Screw Knife Fastening - Special TORX screws lock each knife securely in place during high-speed routing, maintaining accuracy and operator safety throughout the cut.
- Orange Chrome Non-Stick Body Coating - CMT's signature orange chrome coating on the bit body resists heat buildup, guards against corrosion, and minimizes resin and pitch accumulation - keeping the bit running cleaner for longer.
- 1 1/31/32 in. Cutting Height - The generous cutting length handles deep dados and through-cuts in thick stock without multiple passes, saving setup time on the job.
- Right-Hand Rotation - Matches the standard rotation direction of virtually all hand routers and router tables, ensuring immediate compatibility without any modification.
- 1/2 in. Shank Diameter - The full 1/2 in. shank provides superior rigidity and reduced vibration compared to smaller shank sizes, resulting in smoother cuts and a better surface finish.
Why This Product
- The replaceable insert knife design means you are not discarding the entire bit when the cutting edges dull - simply flip or replace the knives to restore sharp performance, lowering your long-term tooling cost.
- At 1-31/32 in. of cutting height paired with a 4-1/16 in. overall length, this bit reaches deep enough for substantial workpieces while still fitting securely in standard 1/2 in. collets on hand routers and router tables.
- The hardwood-grade (HW) insert knives are suited for demanding materials including hardwood, plywood, MDF, chipboard, laminates, and plastics - making this a single versatile tool across multiple material types.
- With TORX-secured knives and orange chrome protection on the body, this bit is engineered for both safety at speed and durability in production routing environments where consistent results matter.
