Frequently Asked Questions
What is the difference between Straight and Spiral flutes?
Straight flutes are easier to sharpen and offer stable drilling. Spiral flutes (Double Flute) offer faster chip removal, smoother cutting, and extended tool life, making them ideal for professional use.
Can your step drills cut Stainless Steel?
Yes, our Extreme Duty M35 (Cobalt) series is specifically designed for stainless steel. For regular steel or iron, our Industrial M2 series is the best choice.
Do you offer custom sets and packaging?
Yes, we provide 3-piece or 5-piece sets in Metal Boxes, Plastic Cases, or Nylon Pouches. We also support custom logo laser printing on the shank.
What is the advantage of the Split Point design?
All our step drills feature a self-centering 118° or 135° Split Point, which prevents "walking" (skating) on the metal surface and eliminates the need for a center punch.
