Lenox 30908 Vari-bit Step Drill Bit Set

Product Description

The LENOX 30908 is a Vari-Bit step drill bit set designed to drill fast, clean round holes in sheet metal, plastic, and thin-gauge materials. The bits feature a split point tip that starts cutting on contact, reducing walking and improving hole accuracy from the first stroke. Step drill bits like these are a standard tool for HVAC and electrical trades where knockout holes and conduit entry points need to be cut cleanly without a pilot drill. Weighing 0.15 pounds, the set is compact and easy to carry in a service bag or pouch.

This set is suited for residential and light commercial trade work involving sheet metal panels, electrical enclosures, junction boxes, and similar thin-material applications. HVAC technicians use step drill bits when installing equipment that requires clean, sized holes for refrigerant line sets, low-voltage wiring, or condensate drain pass-throughs. Electricians rely on them for conduit knockouts and panel work. The stepped profile allows a single bit to cut multiple hole sizes without changing tools.

Key Features

• Split point design starts on contact and reduces bit walking on smooth surfaces
• Step profile cuts multiple hole sizes with a single bit
• Produces fast, clean round holes in sheet metal and thin-gauge materials
• Compact set weight of 0.15 pounds for easy portability on the job

Compatibility

Designed for use with standard electric drills and drill drivers used in HVAC, electrical, and plumbing trade applications involving sheet metal, plastic, and thin-gauge panel materials.

Installation Notes

Step drill bits are typically used by HVAC technicians and electricians for field fabrication and equipment installation tasks. Secure the workpiece before drilling to prevent movement. Use appropriate eye protection and follow applicable safety practices per NEC or local codes when working near energized panels or enclosures. Avoid applying excessive downward pressure, which can distort thin-gauge material around the hole.
