BulletPoint2 : 12 STEPS - The step bit comes with 12 sizes ranging from 4mm to 13mm, so you can drill up to 10 holes of different diameters with one bit, saving you time and efforts to change bits. BulletPoint3 : FOR STAINLESS STEEL - Ideal for drilling new holes or and enlarging existing holes on stainless steel as well as softer metals like iron, brass, copper, aluminum, etc. BulletPoint4 : GOOD PERFORMANCE - The dual-flute design provides greater speed and control along with jam-free performance. The fast-start no-walk tip allows you to drill without a center punch.
