Cle-Line C18442 Jobber Drill Bit
The Cle-Line C18442 is a heavy-duty jobber length drill bit designed for general-purpose drilling tasks. It suits trade professionals and workshop users who need a reliable cutting tool for metal and wood applications.
135 Degree Split Point Geometry
The 135 degree split point angle allows the bit to start on contact without wandering, reducing the need for centre punching. Its parabolic flute design aids efficient chip evacuation during deep-hole drilling, while the black and gold surface treatment adds wear resistance for extended service life.
High Speed Steel Construction
Manufactured from high speed steel, the bit maintains hardness at elevated temperatures generated during continuous cutting. The non-coolant-through design with zero coolant holes means it relies on external lubrication or air cooling, keeping operation straightforward for handheld or stationary use.

Questions about this item
What does the 135-degree split point do for drilling?
The 135-degree split point reduces walking and starts the hole accurately without a centre punch.
What shank size fits a standard drill chuck for this 1/4-inch bit?
The jobber-length bit has a straight shank the same 1/4-inch diameter as the cutting portion, so it fits any three-jaw chuck that accepts 1/4-inch shanks.
How should I run this high-speed steel bit to avoid overheating?
Use cutting fluid or oil, run at the recommended RPM for the material, and apply steady pressure; the bit has no coolant holes, so external lubrication is essential.
