Key features

• PREMIUM STEP BIT: Each unibit is constructed of #4241 industrial high-speed steel (HSS) with a titanium nitride coating for durability and strength to punch and drill clean holes in materials like plastic, aluminum, wood, copper, stainless steel, and other types of sheet metal.
• STEP DRILL BIT FOR METAL: It has a 135-degree split-point tip and features a 2-fluted spiral design that automatically deburrs and expands holes for a cleaner drilling process. With a split point tip that accelerates cutting speed, it prevents walking away from center line of bore, drilling holes in metal is fast, efficient, and clean.
• SPIRAL DESIGN: The stepped drill bit with two-flute spiral grooved design cuts smoother than a straight bit with less chatter, pulls chips up and out of the hole more effectively, runs cooler and handles thicker material and stainless steel better.
• QUICK-CHANGE STEP BIT: The 1/4-inch hex shank snaps into a quick change chuck or impact driver without tightening of a regular drill chuck. Makes for easy, convenient, and fast bit swaps.
• MULTISIZE DRILL BIT: This hole drill bit can drill holes in 10 different sizes: 1/4", 3/8", 1/2", 5/8", 3/4", 7/8", 1", 1-1/8", 1-1/4" and 1-3/8".
