CMT Straight Bit Long Series – 3/8 in. Dia. – 1/4 in. Shank
Produce clean, accurate cuts with the CMT Long Series 3/8 in. Straight Router Bit. Designed for deeper cutting applications, this bit combines premium micro-grain carbide cutting edges with CMT's exclusive Fatigue Proof® steel body for exceptional durability and long-lasting performance. The extended cutting length makes it ideal for routing grooves, dados, mortises, and trimming in hardwoods, softwoods, plywood, MDF, laminates, and composite materials.
Each bit is precision-balanced and manufactured on advanced CNC equipment to deliver smooth, vibration-free operation with excellent chip evacuation for cleaner cuts and longer tool life. CMT's signature orange PTFE non-stick coating helps reduce heat and prevents resin and pitch buildup, keeping the bit cutting efficiently through demanding production work.
