Hertel 07574965 Screw Machine Drill Bit Set 26 Pc Hss

Product Description

The HERTEL 07574965 is a 26-piece screw machine length drill bit set covering the full letter series from A through Z. Built from high-speed steel with a bright uncoated finish, these bits are sized shorter than jobber-length drills, which reduces deflection and improves accuracy in tight setups and drill press work. The 118-degree standard point angle is suited to general-purpose metalworking across a wide range of ferrous and non-ferrous materials. Each bit features a straight shank for compatibility with standard chucks. The set ships in a metal or plastic case that keeps bits organized and protected between uses. Licensed machinists, tool-and-die techs, and maintenance mechanics are the primary users.

This set is intended for metalworking and multipurpose drilling applications in both shop and field environments. Screw machine length bits are a common choice for drill press fixtures, CNC setup work, and benchtop drilling where reduced overhang improves hole quality and bit life. The full A-to-Z letter sizing covers fractional-adjacent diameters used extensively in tap drilling, reaming prep, and close-tolerance work. The set is appropriate for light manufacturing, general maintenance, and production environments that require a complete letter-series complement in a single case.

Key Features

• 26-piece set covers full letter drill series A through Z in a single case
• High-speed steel construction handles general-purpose metalworking and multipurpose drilling
• 118-degree standard point angle for reliable starting and consistent hole geometry
• Screw machine (stub) length reduces deflection and improves rigidity versus jobber-length bits
• Bright uncoated finish — no coating to chip or flake, easy to resharpen
• Straight shank fits standard 3-jaw drill chucks without adapters
• Includes storage case to keep the full letter series organized

Compatibility

Designed for use with standard straight-shank drill chucks in drill presses, benchtop machines, and handheld drills configured for metalworking and general-purpose drilling applications.

Installation Notes

Install bits into a properly rated drill chuck and tighten with a chuck key before operation. Secure workpieces firmly to prevent rotation during drilling. Use appropriate cutting fluid for steel and harder alloys to extend bit life and improve hole finish. Inspect each bit for chipping or dullness before use and resharpen or replace as needed to maintain hole quality.
