Hertel 61698759 Screw Machine Drill Bit 17/64 Hss

Product Description

The HERTEL 61698759 is a screw machine length drill bit designed for high-speed steel cutting in general-purpose metalworking and machining applications. Built from high speed steel with an oxide finish, this bit measures 17/64 inch (0.2656 inches) in diameter and features a 118-degree standard point angle for accurate starting and clean penetration. The shorter screw machine length body — 2.625 inches overall — provides added rigidity compared to jobber-length bits, making it well suited for drill press work, CNC applications, and hand-held drilling in tight clearance situations. It is typically installed by machinists, tool and die professionals, and maintenance mechanics.

This drill bit is intended for general-purpose drilling in metals, plastics, and similar materials where a short, rigid bit is preferred. The 1.4375-inch spiral flute length and 3xD flute-to-diameter ratio support efficient chip evacuation during moderate-depth drilling operations. The straight cylindrical shank seats securely in standard drill chucks without requiring a special adapter. This bit ships individually (package quantity of 1) and meets ANSI specification designations for dimensional consistency.

Key Features

• 17/64 inch (0.2656 inches) diameter with ANSI-compliant dimensions
• 118-degree standard point angle for general-purpose entry and minimal walking
• High speed steel construction with oxide finish for surface protection and reduced friction
• Screw machine length body (2.625 inches overall) for enhanced rigidity in tight setups
• 2-flute regular spiral design promotes consistent chip removal
• Straight cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with any drill press, CNC machine, or hand drill equipped with a standard chuck accepting straight cylindrical shanks in the 17/64 inch size range.

Installation Notes

Installation should be performed by a qualified machinist or maintenance professional. Ensure the drill chuck is fully tightened and the workpiece is securely clamped before operation. Always wear appropriate eye protection and follow shop safety procedures when drilling. Confirm spindle speed is set appropriately for the material and bit diameter before starting the cut.
