Hertel H95006025 Jobber Drill Bit 29/64 in Hss

Product Description

The HERTEL H95006025 is a heavy-duty jobber-length drill bit designed for general-purpose holemaking in metal, wood, and similar materials. It carries a 29/64 inch (0.4531 inch decimal) diameter and a 137-degree split point that reduces walking and cutting pressure at the start of a hole. The bit is manufactured from high speed steel with an oxide finish and is suited for use in standard drill presses, hand drills, and CNC drilling operations. Two spiral flutes evacuate chips efficiently throughout the 3-1/4 inch flute length. Licensed tradespeople and machinists working in HVAC, plumbing, electrical, and general fabrication will find this a reliable stock bit for daily holemaking tasks.

This jobber drill bit is intended for production and maintenance drilling applications across residential, commercial, and light industrial settings. The right-hand cutting direction and regular spiral geometry suit it to conventional drilling in ferrous and non-ferrous materials. With an overall length of 5-5/8 inches and a 29/64 inch diameter, it fills a common hole size requirement found in equipment installation, conduit work, bracket fabrication, and structural attachment tasks. No coolant-through capability is required for standard use.

Key Features

• 29/64 inch diameter (0.4531 inch decimal) for a precise, common holemaking size
• 137-degree split point reduces thrust force and minimizes bit walking on entry
• High speed steel construction rated for heavy-duty drilling service
• Oxide finish provides basic corrosion resistance and lubricity
• Right-hand, regular spiral flute design promotes consistent chip evacuation
• Three flats on the shank for secure chuck engagement and reduced slippage

Compatibility

Designed as an OEM-style jobber drill bit compatible with standard 3-jaw drill chucks accepting straight-shank bits in the 29/64 inch diameter range, conforming to ANSI specifications for jobber-length drill bits.

Installation Notes

Installation of this drill bit is performed by qualified tradespeople using standard drill presses, hand drills, or CNC equipment. Secure the shank fully in the chuck before operation and verify the chuck key is removed before powering on. Always wear appropriate eye protection and secure the workpiece before drilling. Follow applicable OSHA and shop safety standards for drilling operations.
