Hertel 2386431 Screw Machine Drill Bit Size 36 Hss

Product Description

The HERTEL 2386431 is a screw machine length drill bit designed for high-production drilling in metal, plastic, and general-purpose shop applications. Built from high-speed steel with an oxide coating, this bit carries a wire gauge Size 36 diameter of 0.1065 inches and an overall length of 1.8125 inches. The 135-degree split point reduces walking on entry and lowers the thrust needed to start a hole. The web-thinned, parallel-web construction supports clean chip evacuation through the spiral flute. A straight-cylindrical shank seats directly in standard drill chucks. This bit is sold individually and requires a minimum order of 12 units.

Screw machine length bits are the standard choice when a shorter, more rigid tool is needed close to a workpiece or fixture. The reduced overall length compared to jobber-length bits limits deflection, which matters in tight clearances or when drilling on automated or semi-automated equipment. The 13/16-inch flute length is appropriate for shallow-to-moderate depth holes typical in production and maintenance machining environments. Licensed machinists, tool-and-die technicians, and maintenance mechanics are the primary users of this bit style.

Key Features

• Wire gauge Size 36 diameter — 0.1065 inches for precise hole sizing
• 135-degree split point reduces thrust and minimizes drill walk on entry
• High-speed steel construction with oxide coating for lubricity and light corrosion resistance
• Web-thinned parallel web supports efficient chip flow through the spiral flute
• Straight-cylindrical shank fits standard drill chucks without adapters
• Screw machine length body provides added rigidity over jobber-length alternatives

Compatibility

Designed as a standard screw machine length drill bit for use in any drill press, mill, or hand-held drill with a chuck capacity accepting a 0.1065-inch straight shank. Suitable for drilling ferrous metals, non-ferrous metals, and plastics within the 0.1000 to 0.1500 inch drill bit size range.

Installation Notes

Secure the shank fully in the chuck and verify runout before drilling. Power down and lock out any machine before changing bits. Use cutting fluid or coolant when drilling hardened or stainless steel to extend tool life; this bit does not support coolant-through delivery. Verify workpiece is clamped firmly to prevent bit grab on breakthrough.
