Hertel 85703577 Jobber Drill Bit 13/32 in Hss 118 Degree

Product Description

The HERTEL 85703577 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastics. It measures 13/32 inch (0.4062 inch decimal) in diameter with a standard 118-degree point angle and a web-thinned, tapered web configuration that improves penetration and reduces walking on entry. The bit is manufactured from high-speed steel (HSS) with a bright, uncoated finish. Overall length is 5-1/4 inches with a flute length of 3-7/8 inches. Machinists, maintenance technicians, pipefitters, and general tradespeople who need a reliable, straight-shank drill for everyday applications will find this bit suited to their workflow.

This bit is intended for use in standard drill presses, hand drills, and benchtop drilling fixtures where a 13/32-inch straight-cylindrical shank is accepted. It is appropriate for light to moderate production work and general maintenance drilling in ferrous and non-ferrous materials. The right-hand spiral flute design efficiently evacuates chips during drilling. This size falls within the 0.4000 to 0.5000 inch decimal range, making it a common selection for hole prep, clearance holes, and pilot work in fabrication and service environments.

Key Features

• 13/32 inch diameter (0.4062 inch decimal) for precise sizing in general-purpose applications
• 118-degree standard point angle with web-thinned, tapered web for easier penetration and reduced thrust
• High-speed steel construction with bright, uncoated finish for use across a wide range of materials
• Right-hand cut, regular spiral flute with 2 flutes for efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collets
• 5-1/4 inch overall length with 3-7/8 inch flute length for adequate reach in most bench and hand-drill setups

Compatibility

Designed as an OEM-style general-purpose jobber drill bit compatible with standard drill chucks and collets accepting a straight-cylindrical 13/32-inch shank, suitable for drill presses, hand drills, and CNC drilling fixtures configured for this shank type.

Installation Notes

Secure the shank firmly in the chuck and verify concentricity before drilling. Ensure the workpiece is clamped or fixtured to prevent rotation or movement during the cut. Apply appropriate cutting fluid or coolant when drilling hardened or dense materials to extend bit life. Inspect the cutting edges for wear or chipping before each use and replace the bit if point geometry is compromised.
