Hertel 61699534 Screw Machine Drill Bit 0.152 in Hss

Product Description

The HERTEL 61699534 is a screw machine length drill bit designed for close-tolerance drilling in metalworking and general machining applications. Built from high speed steel with an oxide finish, this bit measures 0.152 inches in diameter and corresponds to wire gauge size 24. The 118-degree standard point angle suits a broad range of ferrous and non-ferrous materials. At 2-1/16 inches overall length with a 1-inch flute, the shortened screw machine format reduces deflection and improves rigidity compared to jobber-length bits. Machinists, maintenance technicians, and fabricators working at drill presses, CNC machines, or handheld power tools will find this bit well suited for production and repair work.

This bit is intended for general-purpose drilling in metal, plastics, and similar materials where a compact, rigid drill profile is required. The straight-cylindrical shank fits standard drill chucks without adaptation. The 3xD flute-to-diameter ratio and regular spiral geometry support efficient chip evacuation in shallow-to-moderate depth holes. Right-hand cut operation is standard for conventional drilling setups. It is appropriate for use in screw machine operations, manual drill presses, and benchtop machining environments in light industrial and maintenance settings.

Key Features

• High speed steel construction with oxide finish for general-purpose durability
• 0.152 inch diameter, wire gauge size 24, ANSI specification
• 118-degree standard point angle for broad material compatibility
• Screw machine length (2-1/16 inches overall) reduces deflection in short-reach applications
• Straight-cylindrical shank fits standard drill chucks without adapters
• 2-flute regular spiral design promotes chip clearance during drilling

Compatibility

Designed as an OEM-style general-purpose replacement or stock drill bit for standard drill chucks accepting straight-cylindrical shanks in the 0.1500 to 0.2000 inch decimal inch size range.

Installation Notes

Secure the shank fully in the drill chuck and verify concentricity before operation. Power down and de-energize all equipment before changing or inspecting bits. Use appropriate cutting fluid or coolant for extended tool life when drilling ferrous metals, as this bit does not support coolant-through delivery. Follow applicable shop safety standards and machine manufacturer guidelines for spindle speed selection based on material and bit diameter.
