Lenox 30881VB1 – Frequently Asked Questions
1) What hole sizes will the Lenox step drill bit cut?
The Lenox step drill bit steps from 1/8 inch up to 1/2 inch, so you drill to the step that matches your hole and stop there. That covers most low-voltage and control wiring penetrations; for larger conduit knockouts you need a bigger step bit or a hole saw.
2) Will a step drill bit like this work in an electrical panel or thin gauge sheet metal?
That is what it is built for. Step bits cut clean, round, burr-free holes in thin gauge metal and panel enclosures, where a twist bit tends to grab and triangulate the hole. The two flute design clears chips as you step up, so you are not pulling the bit to clear swarf between sizes.
3) Do I need to center punch or drill a pilot hole first with this step bit?
No. The split point starts on contact, which is what keeps the bit from walking on sheet metal and lets you skip the center punch and pilot hole.
4) Which Lenox part number do I order for the step bit?
Two Lenox part numbers are offered on this step bit: 30881VB1 and 30912VB12. Quote the part number when you order, since the size option on its own does not identify the bit.
5) What does the steam oxide coating on this Lenox step bit actually do?
Steam oxide is a surface treatment that cuts friction and heat buildup at the cutting edges, which is how the bit holds its edge longer than a bright uncoated bit. Lenox rates it at twice the life. It is not a lubricant, so you still want to run slow and let the bit cool between holes in steel.
6) What speed should I run a 1/8 to 1/2 inch step drill bit at?
Start at your drill's lowest speed and increase as the bit engages. Steady, even pressure is the whole trick with a step bit, let the flutes carry the chips out rather than pushing harder. Clean the flutes and let the bit cool between holes, particularly as you work into the larger steps where surface speed climbs.
7) Does this Lenox step bit come with a battery or need power tool accessories?
It's a bare cutting tool, no battery and nothing energy-using about it. You chuck it in a drill you already own. Nothing else is supplied with the bit.
