TITANIUM COATING: Our high-speed steel drill bits, fortified with a titanium coating, offer exceptional durability and maintain sharpness even through demanding tasks. The titanium coating increases wear resistance and minimizes friction, resulting in cooler operation.
TWO FLUTE BITS: Two-flute spiral grooved design deburrs chips, dust and debris for clearance and smooth cutting. The 118°split point tip drill reduces friction, pressure, and heat, making the drill bits long-lasting and efficient.
PREMIUM STEP BITS: Each unibit is constructed of industrial high-speed steel 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.
QUICK CHANGE: The 1/4-inch hex shank makes for easy, convenient, and quick stepper bit switches and is compatible with impact ready power tools.
