Cle-Line C18658 135° Parabolic Jobber Bit
The Cle-Line C18658 is a heavy-duty jobber length drill bit designed for general-purpose drilling in metal, wood, and plastic. It features a 135-degree split point that starts on contact without walking. The parabolic flute design improves chip evacuation in deeper holes.
Suited for 1/2 inch fractional drilling
This bit suits machinists and maintenance crews drilling 1/2 inch diameter holes where a self-centering point is required. The TiN coating on high-speed steel extends tool life in ferrous materials. It is not for applications needing coolant-through capability or metric diameter sizes.
135-degree split point
The defining specification is the 135-degree split point ground on HAWA high-speed steel with a titanium nitride coating. This geometry reduces thrust and prevents walking on hard surfaces. The .5000 decimal equivalent confirms the exact 1/2 inch fractional size.

Questions about this item
What does the 135-degree split point do for drilling?
The 135-degree split point reduces walking and allows the bit to start cutting on contact without a centre punch.
What shank style does this 1/2-inch jobber bit use?
It has a straight round shank that fits standard three-jaw drill chucks up to 1/2-inch capacity.
How should I apply coolant when using this non-coolant-through bit?
Apply cutting fluid externally to the flutes and workpiece; do not attempt to feed coolant through the bit.
