Hertel 66693680 Jobber Drill Bit Set 26 Pc A-z Hss

Product Description

The HERTEL 66693680 is a 26-piece jobber length drill bit set covering the full letter size range from A through Z. Each bit is manufactured from high-speed steel with an oxide finish that reduces friction and helps resist heat buildup during metal removal. The 135-degree split-point tip geometry reduces walking on entry and requires less feed pressure than a 118-degree conventional point. Straight shanks provide positive chuck grip across standard drill presses, hand drills, and benchtop machines. This set is suited for professional metalworking applications where a complete letter-series range needs to be on hand. Licensed tradespeople and industrial maintenance technicians are the primary users.

This set is designed for metalworking and multipurpose drilling in ferrous and non-ferrous metals, plastics, and composite materials. The heavy-duty performance rating makes these bits appropriate for production environments and repetitive-cycle drilling as well as general maintenance tasks. The full A-through-Z letter range covers close-tolerance hole sizing for tapping operations, reaming prep, and precision fit work. All 26 bits store in an included metal or plastic case that keeps each size organized and protected between uses.

Key Features

• Full letter-series coverage from A through Z - 26 bits total

Compatibility

Designed for use in standard three-jaw drill chucks on hand drills, drill presses, and milling machines configured for inch-system tooling. Suitable for metalworking and multipurpose drilling applications.

Installation Notes

Secure the bit fully into the chuck and tighten with a chuck key before beginning any drilling operation. Always power down and de-energize the machine before changing bits. Use appropriate cutting fluid when drilling hardened or stainless steel to extend bit life and improve hole quality. Operators should follow applicable OSHA and shop safety standards when using rotating cutting tools.
