COBALT Step Drill Bit
- Perfect for drilling and enlarging different sized holes without changing the drill bit. Use one single bit for multiple holes
- Ideal for creating burr-free holes in hard metal, plastic, copper, wood, aluminum, and carbon fiber
- Industrial Quality for professionals
- Heat-treated, M35 COBALT steel body material
- COBALT steel adds extra hardness and wear resistance to make the drill bit last longer and drill faster than HSS step drill bits
- Chamfered steps allow the user to slowly progress through multiple sizes and drill up to the desired size step by step for greater accuracy
- Self-centering 135° split point tip prevents “wobbling” by eliminating center punch holes and starting instantly on contact
- Double flute design ensures quick chip removal, removes heat for a “cooler drilling operation”, and extends bit life
- Carded packaging available which is perfect for distributors and resellers
