Hertel 89320832 Screw Machine Drill Bit 9/32 Inch Hss

Product Description

The HERTEL 89320832 is a screw machine length drill bit designed for general-purpose drilling in metal, wood, and plastics. Screw machine length bits are shorter than jobber-length bits, which reduces deflection and improves accuracy in tight spaces, turret lathes, and screw machine setups. This bit measures 9/32 inch (0.2812 inch decimal) in diameter with an overall length of 2-11/16 inches and a flute length of 1-1/2 inches. The 118-degree split point is a standard geometry suited to a wide range of materials. The bright uncoated high-speed steel construction keeps the bit ready to use straight out of the package without any coating to chip or flake during service.

This bit is well-suited to HVAC, plumbing, and electrical trade work where drilling in confined areas or through sheet metal, structural steel, and light-gauge materials is routine. The compact screw machine length makes it a practical choice for right-angle drill attachments, drill presses, and CNC or manual lathe turrets. Right-hand cut geometry works with all standard drill drivers and press spindles. General-purpose grade means it handles the variety of materials encountered on a typical service or installation job without requiring specialty tooling.

Key Features

• Screw machine length body reduces deflection and improves control in confined drilling applications
• 118-degree drill point angle suits general-purpose drilling across metal, wood, and plastic materials
• High-speed steel construction withstands heat buildup during moderate-speed drilling
• Bright uncoated finish requires no break-in and works across a broad material range
• Right-hand cut geometry compatible with all standard drill presses, drivers, and lathe turrets
• 1-1/2 inch flute length provides adequate chip clearance for the short overall length

Compatibility

Designed as a general-purpose screw machine length drill bit for use in standard drill chucks, drill presses, right-angle attachments, and manual or CNC lathe turrets accepting a 9/32 inch shank diameter.

Installation Notes

Install and remove drill bits only with the drill motor fully powered off and the chuck key removed from the chuck. Secure the workpiece before drilling to prevent movement and ensure accurate hole placement. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and manage heat. Inspect the cutting edges before each use and discard bits showing visible chipping or dulling to avoid workpiece damage.
