Lenox 30883VB3 – Frequently Asked Questions
1) What are the Lenox variable step drill bit part numbers for the 3/4 inch and 7/8 inch sizes?
Two sizes are offered. The 3/4 inch version is Lenox 30883VB3, and the 7/8 inch version is Lenox 30908VB8. Order by the largest hole size you need, since a step bit cuts every smaller step on the way up to that maximum.
2) Will a Lenox variable step drill bit cut sheet metal and steel plate, or is it only for wood?
It cuts both. The tooth geometry is built to penetrate metal, and Lenox calls out sheet metal, steel plate and metal fabrication work along with lumber and engineered wood. Larger, sharper teeth clear wood chips quickly, so one bit covers both sides of an electrical rough-in.
3) Do I still need a set of individual twist bits if I buy a Lenox step drill bit?
Not for the diameters the step bit covers. The graduated steps give you multiple hole sizes in one tool, so an electrician punching knockouts for connectors, switches and control panel components can size holes off a single bit instead of swapping through a twist set. You still start at the smallest step and work up through the larger diameters rather than plunging straight to size.
4) How do you get the metal slug out after drilling with a Lenox step bit?
The Speed Slot staircase design ejects the plug, so the slug comes out without prying it off the bit. That is the detail that keeps a panel or duct job moving when you are cutting a run of holes back to back.
5) Does the Lenox step drill bit come with a battery or need a power supply of its own?
No battery, and no power source of its own. The step bit is classified non-energy using, meaning it is a cutting accessory that chucks into a drill you already own, corded or cordless.
6) Is the Lenox step drill bit suitable for HVAC and plumbing work, or just electrical?
It is not electrical-only. Lenox lists it for drilling ductwork, refrigerant line and ventilation penetrations, and for pipe runs, fixture mounting and water line holes, as well as general construction and repair drilling where several hole sizes are needed. An MRO crew running mixed trades can standardize on it.
7) What drill speed should I use with a Lenox variable step drill bit?
Pick the speed off the material and the hole size rather than running one setting for everything, then keep steady, consistent pressure and let the teeth cut instead of forcing the bit. Clearing chips and wiping the bit down during a long run of holes keeps the cutting edges working.
