- 135° split point starts on contact without walking
- Cobalt steel resists heat during hard-metal drilling
- Left-hand flutes extract broken bolts and studs
- Mechanics length gives rigidity in tight spaces
- 7/32 in fractional size fits standard SAE taps
Cobalt Left-Hand Mechanics Drill
The Cle-Line C30514 is a 135-degree cobalt drill bit designed for left-hand rotation in mechanics-length format. It suits technicians who need to extract broken fasteners or machine tough alloys with a single specialised tool. The fractional 7/32-inch size fits standard chuck capacities.
135-Degree Split Point Limits
The 135-degree split point reduces walking on hard surfaces but demands rigid setups and controlled feed pressure to prevent chipping. Cobalt construction handles heat better than high-speed steel yet remains brittle under heavy side loads or interrupted cuts. Left-hand rotation restricts use to reverse-capable drives or dedicated extraction tasks.
7/32-Inch Fractional Diameter
The 0.2188-inch diameter determines whether this bit matches the pilot-hole or extractor size required for the job. Buyers who need a different fractional increment or a metric equivalent must select another part number. No other dimension in the spec alters this core compatibility requirement.

Questions about this item
Should I choose the 7/32 inch cobalt bit for my job?
The 7/32 inch size suits holes of that exact diameter; the cobalt material handles hard metals and high heat better than standard steel.
What does the 135 degree point do when the bit is in a drill?
A 135 degree split point centres quickly on hard metal, reduces walking and needs less thrust than a flatter point.
How does the left-hand flute affect use in a standard drill?
Left-hand flutes are designed for reverse rotation; they will not cut in a normal forward-running drill motor.
