Greenlee Nail Eater Extreme Shorty Bit

Greenlee 50304313 Nail Eater Extreme Shorty Bit, 1-1/8" Heat Treated Steel

The Greenlee 50304313 Nail Eater Extreme is a compact "Extreme Shorty" style bit engineered for fast, aggressive boring through nail-embedded wood and other tough electrical rough-in materials. Built from heat treated steel, this bit features a 1-1/8 IN (28.600 MM) bit diameter, an overall length of 7-5/8 IN (193.700 MM), and a 5.000 IN (127.000 MM) twist length that delivers deep, efficient cutting in a shorter overall footprint. The hexagonal shank design, measuring 7/16 IN (11.100 MM) in diameter, provides a secure, slip-resistant connection to compatible drill drivers for reliable torque transfer during demanding electrical and construction applications. Manufactured in the US, this Greenlee bit is designed for electricians and contractors who need a durable, no-nonsense boring solution that stands up to nail strikes without losing cutting performance. Its shortened profile makes it especially useful in tight joist bays, retrofit cavities, and other confined framing spaces where a full-length auger bit simply won't fit, while still retaining the aggressive cutting geometry Greenlee's Nail Eater Extreme line is known for on the jobsite.

Key Features

• Bit Diameter: 1-1/8 IN (28.600 MM) for boring holes sized for standard electrical and low-voltage cable runs.
• Durable Construction: Heat Treated Steel body resists wear and impact damage when boring through nail-embedded lumber.
• Extreme Shorty Configuration: Compact overall length of 7-5/8 IN (193.700 MM) allows use in tighter joist bays and confined framing cavities where a full-length bit won't fit.
• Twist Length: 5.000 IN (127.000 MM) flute length provides efficient chip and debris clearance during continuous boring.
• Hexagonal Shank: 7/16 IN (11.100 MM) hex shank ensures a secure, slip-resistant fit in compatible drill chucks for consistent torque delivery.
• Compact Footprint: Product dimensions of 8.350 IN length, 1.650 IN width, and 1.550 IN height keep the bit maneuverable on the jobsite and in storage.
• US Manufactured: Produced in the United States to Greenlee's quality standards for professional electrical tooling.
