CMT 812.160.11 Straight Bit Long Series - 16mm Diameter, 1/4 in. Shank is a professional-grade long-series straight router bit engineered for deep, precise cuts in a wide range of wood-based and composite materials. Built with micrograin carbide cutters and CMT's trademark orange non-stick PTFE coating, this 2-flute routing bit delivers smooth, clean edges pass after pass - whether you are cutting dadoes, grooves, or deep panel joints on a handheld router, router table, or CNC routing machine.

Key Features

• Micrograin Carbide Cutters on Special Fatigue Proof Steel - the combination of high-grade steel bodies and micrograin carbide tips means the bit can withstand even the heaviest work loads while still delivering a smooth, precise cut, reducing the need to stop and resharpen between passes.
• Double-Faced Cutter Design - both cutting faces are razor-sharp, producing beautiful clean edges on your finished piece with minimal tearout, so your workpiece comes off the router table ready for assembly or finishing.
• Exceptional Chip Ejection - the flute geometry is optimized to clear waste material quickly and efficiently, allowing cleaner and more constant cutting even in deep passes through solid hardwood or dense sheet goods.
• CMT Orange Non-Stick PTFE Coating - the signature orange surface treatment prevents resin, pitch, and other residue from bonding to the bit body, keeping the cutter running cooler and extending tool life between cleanings.
• Long Series Profile - 1 1/4 in. Cutting Height - the extended cutting length lets you rout deep dadoes, grooves, and template-guided profiles in a single pass that shorter bits cannot reach, saving setup time and improving cut consistency.
• 2-Flute Right-Hand Rotation - the two-tooth configuration balances cutting speed with chip clearance, making it compatible with standard right-hand collet routers and CNC spindles running conventional feed directions.
• 1/4 in. Shank - fits the most common router collet size, making this bit compatible with a broad range of handheld routers and router tables without requiring a reducer bushing.

Why This Product

• The long-series 1 1/4 in. cutting height reaches depths that standard straight bits cannot, making this bit the practical choice for deep dado work, panel joinery, and template routing where a short-series bit would require multiple passes or repositioning.
• The micrograin carbide construction combined with Fatigue Proof steel allows consistent performance under heavy cutting loads - ideal for production environments or long routing sessions where bit fatigue and heat buildup are real concerns.
• The orange PTFE non-stick coating reduces resin and pitch accumulation during cuts through softwoods, laminates, MDF, and melamine - materials notorious for gumming up uncoated bits - so you spend less time cleaning and more time cutting.
• With a standard 1/4 in. shank and right-hand rotation, this bit slots directly into the widest range of routers and CNC routing machines without adapters, making it a versatile addition to any shop that handles solid wood, plywood, chipboard, or plastic routing tasks.
