Drill bit for precision wire-size holes

Cle-Line C23193 #21 135° Jobber Drill Bit 1801 Steam produces a 0.1590 inch hole using high-speed steel with black oxide finish. The 135 degree split point starts on contact and reduces walking on metal surfaces. Jobber length gives standard reach for bench drills and handheld drivers.

Suited for mechanics drilling steel sheet and plate

Works where a #21 wire gauge diameter is specified and split-point accuracy matters. Not for buyers who need coolant-through capability or a different decimal size. Not for applications requiring a larger shank or reduced shank design.

135 degree split point controls entry

The 135 degree point angle with split-point geometry centres the bit without a centre punch. This single feature determines whether the drill matches the required start quality for the job.
