1/4-Inch Jobber Drill Bit
The Cle-Line C23137 is a high-speed steel drill bit with a 135-degree split point designed for general-purpose drilling. It suits maintenance technicians and metalworkers who need reliable hole-making in steel and other ferrous materials.
Sustained Drilling Behaviour
The black oxide finish helps retain lubricity and resist chip welding during extended drilling cycles. The split-point geometry reduces walking at the start and maintains centering as the bit progresses through the workpiece.
Fractional Inch Standard Limits
As a fractional inch tool sized at .2500 decimal equivalent, it fits standard 1/4-inch chucks and collets without metric conversion. The jobber length provides standard reach for bench and handheld drilling, though it does not suit deep-hole or coolant-through applications.

Questions about this item
How much heat does the 135-degree split-point geometry generate when drilling steel all day?
The 135-degree split point reduces thrust and friction, so the bit runs cooler during extended drilling in steel.
What shank size must my drill chuck accept for this 1/4-inch jobber bit to fit?
The bit has a standard 1/4-inch round shank, so any chuck that opens to 1/4 inch or larger will hold it securely.
Will the black-oxide finish on this bit wear off quickly when used with my older high-speed steel drill press?
Black oxide provides corrosion resistance and holds lubricant; it wears gradually but does not affect cutting performance on older machines.
