Hertel 89321715 Screw Machine Drill Bit No. 23 Hss

Product Description

The HERTEL 89321715 is a screw machine length drill bit ground from high-speed steel (HSS) and designed for general-purpose drilling in metal, wood, and plastics. Screw machine length bits are shorter than jobber-length drills, which increases rigidity and reduces deflection in drill press, turret lathe, and screw machine applications. This bit cuts in the right-hand direction with a 118-degree split-free point that suits a broad range of common workpiece materials. The bright, uncoated finish indicates no additional coating treatment, keeping the bit ready to run as-supplied. Overall length is 2-1/16 inches with a 1-inch flute length.

This bit is sized to wire gauge No. 23, which corresponds to a decimal diameter of 0.1540 inches. It is well suited for production drilling, fixture work, and maintenance applications where a compact, rigid drill is preferred over a standard jobber-length bit. The general-purpose grade makes it a practical stock item for machine shops, maintenance departments, and trade professionals who need a reliable wire-gauge drill at modest cost.

Key Features

• Wire gauge No. 23 sizing at 0.1540 inch decimal diameter for precise hole dimensioning
• Screw machine length body reduces deflection and improves rigidity compared to jobber-length bits
• 118-degree drill point angle suitable for general-purpose drilling across common materials
• High-speed steel construction provides adequate hardness and toughness for production and maintenance use
• Right-hand cut, bright uncoated finish — ready to use without additional prep
• 1-inch flute length accommodates typical shallow-to-moderate depth drilling requirements

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with standard drill chucks, drill presses, turret lathes, and CNC screw machines that accept wire-gauge tooling in the 0.1500 to 0.2000 inch diameter range.

Installation Notes

Secure the bit firmly in a properly sized drill chuck before operating; a loose bit can walk or damage the workpiece. Always power down and lock out the machine before changing bits or inspecting the cutting edge. Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Dispose of worn bits safely, as the cutting edges remain sharp even when the bit no longer drills effectively.
