Greenlee 50398733 High-Speed Steel Pilot Drill Bit, 1/4 IN Replacement

Greenlee 50398733 High-Speed Steel Pilot Drill Bit, 1/4 IN Replacement

The Greenlee 50398733 is a High-Speed Steel Pilot Drill Bit engineered as a replacement bit for hole saw and hole cutter assemblies used throughout electrical rough-in work. This pilot drill measures 1/4 IN in bit diameter and 4-1/8 IN overall length, making it a precise, durable fit for centering hole saws when cutting through metal, wood, and other common construction materials encountered on the job site. Manufactured in the US, this pilot bit is built to hold up under repeated use where accuracy and tool longevity matter most, letting electricians and contractors keep existing hole saw kits productive instead of replacing full assemblies every time a pilot bit wears out.

Key Features

• Bit Diameter: 1/4 IN for precise pilot hole placement ahead of hole saw cuts, helping keep the cutter centered and reducing walking or wandering during drilling.
• Overall Length: 4-1/8 IN, sized to guide standard hole saw arbors and cutters accurately through panels, enclosures, boxes, and framing.
• High-Speed Steel Construction: Built from high-speed steel for durability and resistance to wear during repeated drilling applications, supporting a longer service life than standard carbon steel pilot bits.
• Replacement Pilot Bit: Designed as a Pilot, Replacement type bit, allowing electricians and contractors to keep hole saw kits in service without replacing entire assemblies, saving both time and tooling cost.
• Compact Footprint: Product dimensions of 1.400 IN height, 1.800 IN width, and 6.200 IN length with a volume of 15.624 CI, sized for point-of-purchase display and easy storage in a tool bag or truck box.
