Hertel C.E96.S115-1 Drill Bit Set 115 Pc Hss

Product Description

The HERTEL C.E96.S115-1 is a 115-piece screw machine length drill bit set made from high-speed steel (HSS) with a bright, uncoated finish. Screw machine length bits are shorter than jobber-length bits, providing greater rigidity and reduced deflection when drilling in confined spaces or on production machinery. The set covers wire gauge sizes number 60 through number 1 and letter sizes A through Z, all ground to a standard 118-degree split point. It ships in a metal index case. This set is used by machinists, tool and die technicians, and maintenance tradespeople who need a complete inch-system drill assortment on hand.

This set is suited for metalworking and general-purpose drilling applications in job shop, maintenance, and production environments. The shorter flute length of screw machine bits makes them a practical choice for drill press work, turret lathes, and hand drilling where bit walkout or chatter is a concern. Coverage from number 60 wire gauge through letter Z provides the range needed for tapping preparation, clearance holes, and close-tolerance work across a wide variety of metals and materials.

Key Features

• 115-piece set covering wire gauge number 60 to number 1 and letter sizes A through Z in inch measurement
• Screw machine (stub) length for increased rigidity and reduced deflection versus jobber-length bits
• High-speed steel construction for general-purpose metalworking and multipurpose drilling
• Standard 118-degree drill point angle with straight shank for use in standard drill chucks
• Bright, uncoated finish — no coating buildup to affect hole tolerance on close-tolerance work
• Stored in a metal index case for organized access and job site durability
• Step increments of 1/64 inch; maximum hole size 1/2 inch

Compatibility

Designed for use in standard drill chucks accepting straight-shank bits across drill presses, turret lathes, hand drills, and CNC machines set up for inch-system tooling in metalworking and general-purpose applications.

Installation Notes

Secure each bit firmly in the chuck before operation and verify the shank is fully seated to prevent slippage. When drilling metal, use appropriate cutting fluid to extend bit life and maintain hole quality. Inspect bits regularly for wear or chipping and replace individual sizes as needed. Dispose of worn HSS tooling in accordance with local shop waste procedures.
