Hertel 89321038 Drill Bit Letter G 118 Degree Hss

Product Description

The HERTEL 89321038 is a screw machine length drill bit sized to Letter G (0.2610 inches decimal equivalent) and ground to a 118-degree point angle. Manufactured from high-speed steel with a bright, uncoated finish, this bit is designed for general-purpose drilling in metal, wood, and plastics. The shortened overall length of 2-5/8 inches provides greater rigidity compared to jobber-length bits, reducing deflection in applications where hole location accuracy matters. Right-hand cut geometry makes it compatible with standard drill chucks and spindles. HVAC techs, plumbers, electricians, and maintenance trades keep screw machine length bits on hand for confined-space drilling where a jobber bit would be too long to run.

This drill bit is suited for use in drill presses, CNC machines, hand drills, and right-angle drill attachments where a shorter, stiffer bit is preferred. The 1-7/16-inch flute length provides adequate chip evacuation for typical through-hole and blind-hole work in sheet metal, light structural steel, copper pipe fittings, electrical enclosures, and similar trade materials. It is a general-purpose tool intended for intermittent production and service work rather than high-volume continuous machining.

Key Features

• Letter G size — 0.2610 inches decimal equivalent, falls within the 0.2500 to 0.3000 inch size range
• 118-degree point angle for general-purpose drilling across common trade materials
• High-speed steel construction provides toughness and heat resistance for metal drilling
• Screw machine (stub) length at 2-5/8 inches overall increases rigidity and reduces bit deflection
• Bright, uncoated finish — no coating buildup to affect hole diameter tolerance
• Right-hand cut, compatible with all standard clockwise-rotating drill chucks and spindles

Compatibility

Designed as a general-purpose screw machine length drill bit suitable for use in standard drill chucks and spindles accepting round-shank bits in the 0.2500 to 0.3000 inch diameter range.

Installation Notes

This bit is installed and operated by any trade professional performing drilling tasks as part of system installation or service work. Secure the bit fully in the chuck and verify it runs true before applying feed pressure. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and improve hole finish. Wear appropriate eye protection per applicable shop and jobsite safety standards whenever operating drilling equipment.
