Double Cut Solid Carbide Burr Bits for Locksmiths
Fine double-cut burr bits sized for lock work – small heads, controlled bite, chamber-safe cutting.
Design and Construction
Locksmith-spec double-cut burr bits: small heads (3-6 mm) with fine crossed flutes on slim shanks. The fine double cut takes a small, controlled bite – essential when the workpiece is a cylinder you must not distort.
How It Works
Fine crossed flutes shear small chips at high RPM; light pressure plus the small head keeps heat and distortion away from the cylinder.
Applications
Locksmith service, keyway repair, pin-chamber cleanup, small-lock maintenance.
Field Cases
- Lock service: pin chambers cleaned without ovalising the bore.
- Key cutter: warded keyway burrs dressed to spec.
- Trade school: fine double cut taught as the controlled-entry default.
