Product Review

When a regular drill bit tears your sheet metal into shreds, use the ABN Stepped Drill Bit to cut neat and precise holes on plastic, wood, sheet metal, steel, brass, aluminum, and copper. This hole drill cone bit is constructed from steel with a titanium coating and has a 2-flute design for smoother cutting that deburrs as you drill holes with precision. The 1/4-inch drive shank has 3 flat side cutouts that offer a stronger, better grip on a standard drill chuck. This bit works best if you drill a "pilot hole" first and use cutting oil when drilling or cutting metal. Allow cooling during use. The 13 step sizes are in increments of 1/32-inch and include 1/8", 5/32", 3/16", 7/32", 1/4", 9/32", 5/16", 11/32", 3/8", 13/32", 7/16", 15/32", and 1/2".
