Cobalt drill bit, 7/32 inch, straw finish, left-hand spiral

Cle-Line

Cle-Line C30514 135 Degree Cobalt Left-Hand Mechanics Length Drill

SKU CH-Z5NV-5D8HZ

A 7/32 inch cobalt mechanics-length drill bit with a 135-degree split point and left-hand cutting direction

  • 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.
