Multiple Hole Sizes in One Stepped Bit
Use the graduated cutting steps to make or enlarge holes to the selected diameter with a compatible drill. These supplier-listed high-speed steel step drill bits have hex shanks and marked steps, with a choice of a single bit or three-piece sets.
Choose the required bit configuration. A single-bit option includes one bit, not the full set. Drills shown in photos are not included; confirm storage-pouch inclusion for your selected set.
Available Configurations
- Three-piece smaller-range set: two bits covering approximately 0.157–0.472 in with different step spacing, plus one approximately 0.157–0.787 in bit.
- Single larger-range bit: approximately 0.157–1.260 in cutting range.
- Three-piece mixed-range set: approximately 0.157–0.472 in, 0.157–0.787 in and 0.157–1.260 in cutting ranges.
Cutting ranges above are approximate inch conversions of the supplier's metric sizes. These are metric-stepped bits, not an inch-sized step set; check the individual step markings for the required hole size.
Design Details
- Supplier-listed high-speed steel construction with a gold-colored surface finish.
- Stepped cone profiles with marked cutting diameters.
- Pictured hex shank width: 0.25 in.
- Pictured overall lengths vary by design, approximately 2.64–4.02 in.
Before Use
Confirm suitable workpiece materials, maximum thickness and recommended drill speeds with the supplier. The exact coating composition and suitability for hardened steel or impact use have not been verified.
Secure the workpiece, wear eye protection and follow your drill's instructions. Keep hands, loose clothing and hair away from rotating parts. Allow the bit and workpiece to cool before handling.
