Questions about this product
- Why use a step bit instead of regular drill bits?
- One step bit drills several hole sizes, so you skip swapping bits mid-job. The stepped cone bores clean, burr-free holes in one pass. It's great for opening up holes in junction boxes or sheet metal for conduit and hardware.
- What is the bit made of and how long does it last?
- It's high-speed steel with a titanium nitride coating, hardened to around 62 to 64 HRC. The coating cuts friction and resists heat up to about 600C, so the edge stays sharp longer. That construction holds up to repeated drilling in tough material.
- What materials can I drill with this set?
- It's made for wood, sheet metal, plastic, and softer metals like aluminum and mild steel. It is not meant for hardened steel, masonry, or tile. The straight shank fits standard drill chucks, typically 3/8 inch or 1/2 inch.
