CMT Solid Carbide Straight Bit - Short Series, 7mm Diameter, 1/4 in. Shank by CMT is a precision-ground routing bit engineered for demanding production environments where clean, accurate cuts in wood, plywood, composites, and plastics are essential. Built from micrograin solid carbide and protected with CMT's signature orange non-stick coating, this short-series straight bit delivers consistent performance whether you are running a handheld router, a router table, or a CNC routing machine. Its compact overall length makes it a practical choice for mortising, dadoes, grooves, and template routing where rigidity and cutting accuracy matter most.

Key Features

• Solid Micrograin Carbide Construction - the bit is manufactured from micrograin carbide, giving it the hardness and edge retention needed to handle heavy production workloads without rapid wear or edge failure.
• Fatigue-Proof Steel Body - the shank and body are made from special fatigue-proof steel, reducing the risk of stress fractures or breakage under sustained cutting loads and contributing to operator safety.
• Orange Non-Stick P.T.F.E. Coating - CMT's trademark orange surface treatment keeps resin, pitch, and other residue from bonding to the bit, which means less cleaning time, reduced heat buildup, and extended tool life across long production runs.
• 2-Flute Design, Right-Hand Rotation - the double-edged geometry clears chips efficiently in right-hand rotation, producing smooth surfaces and minimizing tear-out in solid hardwood, softwood, plywood, MDF, chipboard, laminates, and melamine.
• Short Series Profile - the reduced overall length of 1 7/8 in. and cutting height of 23/32 in. maximize rigidity at the cutting edge, limiting deflection and improving dimensional accuracy in repeat cuts.
• Strict Quality Testing for Tolerance, Balance, and Concentricity - every bit passes rigorous factory inspection, so you can rely on predictable performance and consistent results from the first cut to the last.

Why This Product

• For production environments where consistency cannot be compromised, the combination of micrograin carbide and strict tolerance testing means this bit runs true cut after cut, reducing scrap and rework.
• The orange P.T.F.E. non-stick coating addresses one of the most common causes of bit degradation - resin and pitch buildup - keeping the bit performing at its rated capacity longer and reducing the frequency of bit changes.
• The short-series geometry is specifically suited to applications where bit deflection is a problem, such as mortising narrow workpieces or following templates, where a longer bit would flex and introduce dimensional errors.
• With a 1/4 in. shank, this bit is compatible with a wide range of handheld routers, router tables, and CNC routing machines, making it a versatile addition to any shop running plywood joinery, composite panel work, or natural wood projects.
