What it is

The Unibor 06S1EIMPCO Impact Pro Step Drill is a spiral-flute cutting tool designed to enlarge holes from 1/8 inch to 1/2 inch in a single pass. It suits metalworkers and maintenance technicians who need quick, repeatable step sizes without changing bits.

The deciding spec

The spiral flute geometry is the specification that determines whether this drill matches the job; it controls chip evacuation and cutting smoothness in sheet metal and plate. Buyers who need a straight-flute or split-point design for different chip control should look elsewhere.

Thermals, noise, power

Friction heat builds at the cutting edges during prolonged use, so cutting fluid or periodic pauses keep the tool within normal operating temperature. The drill produces typical high-speed steel drilling noise and draws power only from the driver motor it is chucked into.
