Stanley 30887vb7 Step Drill Bit 7/8 Inch Conduit

Product Description

The STANLEY 30887vb7 is a Vari-Bit step drill bit designed to produce clean, precise holes in sheet metal, thin-gauge steel, and electrical conduit applications. With a final hole diameter of 7/8 inch and a 3/8-inch shank, this bit is built to handle knockout and conduit prep work that electricians and conduit installers perform regularly. The step design allows a single bit to drill and deburr in one pass, reducing tool changes on the job. This bit ships as a single unit and is manufactured by Stanley Black and Decker in the United States.

This step bit is matched for drilling 1/2-inch conduit entry holes, making it a practical choice for residential and light commercial electrical rough-in work. Electricians use step bits like the 30887vb7 when working with enclosures, panel knockouts, junction boxes, and thin-wall conduit fittings where a standard twist bit would walk or produce a ragged edge. The 3/8-inch shank fits standard drill chucks commonly found on corded and cordless drills used in the field.

Key Features

• 7/8-inch final hole diameter sized for 1/2-inch conduit entry
• 3/8-inch shank compatible with standard drill chucks
• Step design drills and deburrs in a single operation
• Manufactured in the United States by Stanley Black and Decker
• Single-pack unit for individual replacement or kit supplementing

Compatibility

Designed for drilling 1/2-inch conduit knockout holes in sheet metal, electrical enclosures, and junction boxes. Fits any drill with a standard 3/8-inch or larger chuck.

Installation Notes

Licensed electricians typically install conduit fittings and perform enclosure knockouts under NEC guidelines. Always de-energize and lock out any panel or enclosure before drilling nearby live conductors. Use a center punch to prevent bit walking on smooth metal surfaces. Eye protection is required when operating step drill bits in metal.
