Four Spiral Flute Cobalt Step Drill Bit V2.0
$39.99
- All Sizes, One Set: This 4-piece combo is expertly paired to provide the most comprehensive coverage of all common sizes from 1/8" to 1-3/8". All four bits are neatly stored in a single compact kit box. Lightweight, complete, and ready for any job.
- Smooth & Fast: Four-spiral flute design delivers a smoother, faster cut with every turn. Feels like a hot knife through butter – no forcing, no chatter, just clean holes every time.
- Tougher & Lasting: With a TiAlN coating that hits 89HRC surface hardness, you can drill through harder materials at higher speeds without wearing the bit down. Built to keep going, job after job.
- Versatile & Adaptable: Engineered from M35 cobalt HSS, these bits deliver flawless results across stainless steel, steel plates, aluminum, copper, wood, and plastic – each material drilled cleanly and precisely.
- Use with Care: These bits feature a six-sided hex shank, designed for drill presses and power drills – not for impact drivers. To extend bit life, apply steady pressure, match speed to material, and clean flutes regularly to clear metal chips.
