Cle-Line C18655 29/64 in Drill Bit
This Cle-Line C18655 drill bit is a jobber-length cutting tool sized at 29/64 in with a decimal equivalent of .4531. It is built from high-speed steel with a titanium nitride coating for extended wear life. The 135-degree split-point geometry allows self-centering starts on metal surfaces. It suits maintenance technicians and fabrication shops needing precise fractional-inch holes.
135-Degree Split Point for Direct Drilling
The 135-degree split point reduces walking on contact, so the bit engages the workpiece without a centre punch or pilot hole. This frees up cycle time on drill presses and handheld units alike. The parabolic flute profile clears chips efficiently from deep holes. The straight shank fits standard three-jaw chucks and quick-change adapters.
TiN Coating Extends Tool Life
The titanium nitride surface treatment lowers friction and resists heat buildup during high-speed drilling. This coating change means fewer bit replacements on repetitive production runs. No coolant holes are present, so external lubrication is required for tough alloys. The jobber length provides standard reach for general-purpose bench work.

Questions about this item
How long can the 29/64 in bit maintain cutting performance in hardened steel before the 135 degree split point dulls?
The 135 degree split point on this high speed steel bit resists walking and reduces thrust, extending usable life in tough materials.
Does the TiN coating on the C18655 reduce heat buildup during continuous drilling in a production environment?
The TiN coating lowers friction and heat at the cutting edges, helping the bit run cooler during extended jobber length operations.
What shank size must my drill chuck accept to use this 0.4531 in diameter fractional inch bit?
The jobber length design fits standard three jaw chucks that accommodate up to 1/2 in shank capacity.
