The CMT 195.164.11 is an extra-long upcut spiral router bit engineered specifically for door lock set machining, where deep plunge cutting and clean chip evacuation are critical. Constructed from premium solid tungsten carbide with three spiral cutting edges (Z3), it delivers a consistent finish on the underside of the workpiece whilst maintaining efficient upward chip ejection throughout the cut. The extended geometry — 16 mm diameter, 120 mm cutting length, 170 mm overall length — makes it well suited to deep mortising operations that standard-length bits cannot reach. It performs at high feed rates on well-clamped workpieces and is compatible with machining centres, point-to-point machines, and CNC routers. Applications: Door lock set machining, deep mortising, ripping, template routing, panel sizing, solid wood routing, wood composite routing Key Features: — Premium solid tungsten carbide construction — Hardwearing cutting performance and extended tool life across demanding production runs — Three spiral cutting edges (Z3) — Balanced cutting forces and smoother surface finish compared to single or twin-flute alternatives — Upcut geometry — Directs chips upward and away from the cut, keeping the flute clear and reducing heat build-up — Extra-long cutting length — 120 mm — Enables deep mortising for door lock sets that standard-length bits cannot accommodate — 170 mm overall length — Provides the reach required for deep-stack or thick-section workpieces without sacrificing rigidity — 16 mm diameter — Appropriate bore size for door lock set mortise profiles across standard door thicknesses — Clean finish on the underside of the workpiece — Reduces secondary sanding or clean-up on the exit face, important where both faces are visible — Rated for high feed speeds on clamped workpieces — Supports productive cycle times in CNC production environments without compromising cut quality — Compatible with machining centres, point-to-point machines, and CNC routers — Integrates directly into existing CNC tooling setups without adaptors or special holders Scott+Sargeant Woodworking Machinery Ltd 1 Blatchford Road, Horsham, West Sussex RH13 5QR ENGLAND scosarg
