The Irwin Unibit Step Drill Bit #4 makes drilling round holes in thin materials easier and more effortless than conventional drill bits. The self-starting high-speed steel bit can drill up to twelve progressively larger diameters from a quarter to seven eighths of an inch, saving you the cost of an entire set. The cutting edge enters the material one step at a time, cutting rapidly in small bites without straining your drill motor. Perfect for drilling through wood, composite board, plexiglass and plastics that commonly crack with regular drill bits.
Irwin Unibit #4 Step Drill Bit allows you to drill up to 12 different hole sizes with the same bit, from 3/16" to 7/8" (4.8 -22.2 mm)
Eliminates the need to maintain a toolbox full of specific size drill bits
Made from durable heat-treated molybdenum steel
Easy-to-sharpen, non-skid tip eliminates skidding and the need for center punching
Single-fluted cutting edge helps assure true round holes and allows greater control
Tip gives sure starts even on curved surfaces
3 flatted shanks prevent drill chuck slipping
Laser-engraved measurements with increments of 1/16" (1.6 mm)
Ideal for use when cutting through thin materials such as pipes, sheet metal, car dashboards and more
Shank size: 3/8" (9.5 mm)
