Hertel H95006017 Jobber Drill Bit 21/64 in Hss 137 Deg

Product Description

The HERTEL H95006017 is a high speed steel jobber-length drill bit designed for holemaking in metal, wood, and general-purpose materials. It carries a 21/64 inch (0.3281 inch decimal) diameter and a 137-degree split point that reduces walking and lowers thrust force at entry. The oxide and gold coating provides surface hardness and lubricity to extend tool life under repeated use. With a 4-5/8 inch overall length and a 2-1/2 inch flute length, this bit fits standard drill chucks and is sized for production and maintenance drilling. Licensed trades and industrial machinists will find it suited to everyday holemaking tasks.

This jobber drill is intended for general holemaking applications across maintenance, repair, and light manufacturing environments. The heavy-duty grade construction makes it appropriate for repeated use in steel, aluminum, plastics, and similar materials. Its right-hand spiral flute geometry evacuates chips efficiently during through-hole drilling. The ANSI specification designation confirms it meets standard dimensional tolerances expected in trade and industrial settings.

Key Features

• 137-degree split point reduces bit walking and decreases required entry thrust
• High speed steel construction with oxide and gold coating for improved wear resistance
• Right-hand spiral flute with regular helix for efficient chip evacuation
• Heavy-duty grade rating suitable for production and repetitive drilling cycles
• ANSI specification compliant for consistent dimensional tolerances
• Three flats on shank for secure chuck grip and reduced slippage

Compatibility

Designed as a standard jobber-length drill bit for use in handheld drills, drill presses, and CNC drilling equipment accepting round shank bits in the 21/64 inch diameter range.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with drill press and handheld drilling equipment. Secure the shank fully in the chuck before operation and verify chuck key is removed prior to starting the machine. Use appropriate cutting fluid or lubrication when drilling ferrous metals to extend bit life and maintain hole quality. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point is damaged.
