CMT Straight Bit Long Series - 1/2 in. Diameter, 1/2 in. Shank is a professional-grade long-series straight router bit engineered for deep, clean cuts in wood and wood-based composites. Crafted by CMT with micrograin carbide cutters and a fatigue-proof steel body, this bit delivers smooth, precise results across demanding routing tasks including dadoes, grooves, template routing, and panel joinery. The extended cutting height makes it the go-to choice when standard-length bits simply cannot reach, and the razor-sharp double-faced cutters handle even the heaviest workloads without sacrificing surface quality.

Key Features

• Micrograin Carbide Cutters on Fatigue Proof Steel Body - the combination of micrograin carbide cutting edges and a specially hardened steel body means the bit resists deflection and edge failure even under heavy, sustained cutting loads, giving you a smooth and precise cut every time.
• Double-Faced Cutters - both faces of each cutter are sharpened, producing a clean, finished edge on the workpiece without tearout or splintering, which reduces the need for secondary sanding or cleanup.
• Exceptional Chip Ejection - the geometry of this bit is designed to evacuate chips rapidly during the cut, keeping the cutting zone clear and allowing for more constant, uninterrupted routing passes through solid hardwood, plywood, MDF, and other materials.
• CMT Orange PTFE Non-Stick Coating - the trademark orange surface treatment repels resin, pitch, and other wood residue so the bit stays cleaner longer, runs cooler, and maintains its edge sharpness through extended use without buildup slowing the cut.
• 2-Flute, Right-Hand Rotation - the 2-flute design balances material removal rate with cut quality, making this bit compatible with handheld routers, router tables, and CNC routing machines in right-hand rotation setups.
• 1 1/2 in. Cutting Height on a 3-3/4 in. Overall Length - the long-series geometry allows you to rout deep dadoes, through-grooves, and full-depth panel profiles that shorter bits cannot complete in a single pass.
• 1/2 in. Shank - the full 1/2 in. shank provides maximum grip and vibration dampening in the collet, reducing chatter and improving surface finish quality compared to smaller-shank alternatives.

Why This Product

• When a job calls for deep straight cuts - dadoes, housing joints, or full-panel grooves - the 1 1/2 in. cutting height of this long-series bit lets you complete the cut in fewer passes or even a single pass, saving time and improving consistency across repeated cuts.
• The micrograin carbide cutters combined with the PTFE non-stick orange coating extend the usable life of the bit by resisting both mechanical wear and residue buildup, making this a cost-effective choice for shops that route high volumes of solid hardwood, plywood, MDF, and laminates.
• Exceptional chip ejection keeps the cut path clean during long routing passes, which is especially valuable on router tables and CNC setups where interrupted feeds can cause burning or surface defects on the finished piece.
• The double-faced cutter design means both sides of the bit are doing finishing work simultaneously, resulting in a cleaner edge on the finished piece with no additional processing - a direct productivity benefit for cabinetry, joinery, and panel fabrication work.
