Irwin Step Drill Set 4-Pc. (#1 #2 #3 #1T)

IRWINÆ UnibitÆ Step Drill Set 4-Pc No 1, 2, 3 and 1T helps you get the results you want every time you need to drill into sheet metal including copper, brass, aluminum, mild steel or plexiglass.

These Unibit step drill bits feature a single-flute edge for increased control and accuracy as you cut through different step sizes.

Every bit in the Irwin step drill bit set has a SpeedPointÆ non-skid tip design to prevent skidding for more accurate holes and negates the need for center punching before drilling.

The shank design gives the bit a snug fit in the drill chuck.

The Unibit step drill set features Cobalt steel fabrication, high-speed steel or titanium nitrate coatings for heavy-duty use.

Each bit fits a standard 1/4-inch drill chuck, and 1 and 2 bits fit standard quick-change adapters.

California Proposition 65 Warning.
