- PREMIUM STEP BIT: 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.
- STEP DRILL BIT FOR METAL: With a split point tip that accelerates cutting speed while preventing angled walking away from center line of bore, drilling holes in metal is fast, efficient, and clean.
- SPIRAL DESIGN: The two-flute spiral grooved design deburrs chip, dust and debris for clearance and smooth cutting. With 50 step sizes combined, each hole made with these step bits will be precise.
- 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.
- INCLUDES: Each bit set comes with 5 drill bits of a combined 50 sizes: Range is from 1/8” to 1-3/8”.
- Titanium Nitride coating ensures the bit stays cool, reduces friction, and stays durable to last through countless drills.
- Quick Change Hex Shank makes it easy for bit switches and is compatible with most impact ready power tools, electric drills, and bench drills
- 135° Split Point Tip increases cutting speed with self-centering and prevents walking
