HSS 1/2″ Short Step Drill Bit
Compact professional HSS (High-Speed Steel) step drill bit designed for working in tight and hard-to-reach areas of automotive body panels. Its short, compact design makes it especially useful where a conventional longer drill bit and drill have limited working clearance. It is particularly convenient for drilling access holes during PDR repairs in rear quarter panels, internal body cavities, and other areas with restricted access.
Seven progressive steps allow multiple hole sizes from 1/8″ to 1/2″ to be drilled with a single tool.
The stepped design also allows existing holes to be enlarged gradually and precisely.
