Hertel 61699385 Screw Machine Drill Bit Wire 37 Hss

Product Description

The HERTEL 61699385 is a screw machine length drill bit designed for high-speed steel cutting applications in metal, plastics, and general-purpose materials. Wire size 37, this bit measures 0.1040 inches in diameter with an overall length of 1-13/16 inches and a flute length of 13/16 inches. The 118-degree standard point angle delivers fast, accurate starting without a center punch on most metals. The oxide finish reduces friction and provides light corrosion resistance during use. With a straight-cylindrical shank and two regular spiral flutes, this bit seats securely in standard drill chucks and runs smoothly at typical feed and speed rates for its diameter class.

Screw machine length drill bits are shorter than jobber-length bits, making them the preferred choice in tight clearance situations, turret lathes, CNC machining centers, and drill presses where reduced overhang improves rigidity and accuracy. The 61699385 is suited for production environments, maintenance shops, and trade professionals working on HVAC brackets, electrical panels, plumbing fixtures, and general fabrication. Its general-purpose grade and ANSI-specification construction make it a reliable stock item for everyday drilling tasks where a standard jobber bit is too long or too flexible for the application.

Key Features

• Wire size 37 diameter - 0.1040 inches for precision small-hole work
• 118-degree standard point angle for fast engagement on common metals and plastics
• Screw machine length (1-13/16 inches OAL) for improved rigidity in confined spaces
• High-speed steel construction rated for general-purpose cutting across a wide range of materials
• Oxide coating reduces friction and provides light surface protection
• Right-hand cut with regular spiral flutes and straight-cylindrical shank for universal chuck compatibility

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with any standard drill chuck or collet accepting a straight-cylindrical shank in the 0.1040-inch diameter range, conforming to ANSI specifications.

Installation Notes

Install in a drill press, hand drill, or CNC spindle with the shank fully seated in the chuck before tightening. Always wear eye protection and secure the workpiece before drilling. Verify spindle speed is appropriate for the material and bit diameter before operation. Inspect the cutting edges for wear or chipping before each use, particularly in production environments.
