Hertel 61698395 Screw Machine Drill Bit 5/32 Hss

Product Description

The HERTEL 61698395 is a screw machine length drill bit designed for general-purpose metal drilling in tight-clearance and production environments. Built from high speed steel with an oxide finish, this bit measures 0.1562 inches (5/32 inch) in diameter and delivers a 118-degree standard point angle for reliable center-starting on most common workpiece materials. At 2-1/16 inches overall length with a 1-inch flute length, the stub-body design reduces deflection and improves rigidity compared to jobber-length bits. Machinists, tool and die workers, and maintenance technicians install this type of bit in drill presses, CNC machines, and hand drills for repetitive close-tolerance hole work.

This screw machine length drill bit suits residential and commercial maintenance, light fabrication, and production drilling operations where a compact bit length is required. The straight-cylindrical shank seats directly into standard chucks without adapters. The 3xD flute-to-diameter ratio and two-flute spiral design provide efficient chip evacuation on steel, aluminum, and similar materials. It is a single-piece, per-unit offering appropriate for bench stock or individual replacement in a tool kit.

Key Features

• 5/32 inch (0.1562 inch) diameter fits standard fractional drill charts
• 118-degree standard point angle for general-purpose drilling on ferrous and non-ferrous metals
• High speed steel construction with oxide finish for corrosion resistance and reduced friction
• Screw machine (stub) length body minimizes deflection in short-reach drilling applications
• Right-hand cut, two-flute spiral design promotes consistent chip clearance
• Straight-cylindrical shank fits standard three-jaw and keyless chucks without adapters

Compatibility

Designed as a general-purpose replacement screw machine length drill bit compatible with standard drill chucks accepting a straight-cylindrical shank in the 0.1500 to 0.2000 inch diameter range per ANSI specification.

Installation Notes

Installation is performed by machinists, tool and die technicians, or maintenance trades using a drill press, lathe, or hand drill with a compatible chuck. Secure the shank fully in the chuck and verify concentricity before drilling. Always wear appropriate eye protection and ensure the workpiece is clamped or fixtured. Coolant-through is not supported on this bit; apply cutting fluid externally when drilling harder materials to extend tool life.
