Hertel C.E96.S13B Cobalt Drill Bit Set 13 Pc Aircraft

Product Description

The HERTEL C.E96.S13B is a 13-piece aircraft extension length drill bit set built for metalworking professionals who need extra reach and reliable performance in tight or deep drilling applications. Made from cobalt steel with a bright uncoated finish, these bits handle hardened metals, stainless, and high-strength alloys without losing edge integrity. The 135-degree split point starts on contact without a center punch, reducing walking on curved or uneven surfaces. With an overall length of 6 inches and sizing that steps up in 1/64-inch increments from 1/16 inch to 1/4 inch, this set covers a practical range for structural, sheet metal, and general fabrication work.

This set is suited for metalworking and multipurpose drilling tasks in both residential and commercial trade environments. Aircraft extension length geometry gives technicians the clearance needed when working around framing, ductwork, structural steel, or in confined spaces where standard-length bits cannot reach. The heavy-duty rating makes these appropriate for production drilling, maintenance repair, and fabrication shops. Bits are stored in an open metal stand that keeps each size organized and accessible on the bench or in a service vehicle.

Key Features

• Cobalt construction resists heat buildup when drilling hardened metals and stainless steel
• 135-degree split point eliminates bit walking and reduces the need for a center punch
• Aircraft extension length at 6 inches total provides reach in confined or deep-clearance applications
• Size range from 1/16 inch to 1/4 inch in 1/64-inch step increments covers common structural and sheet metal hole sizes
• Bright uncoated finish allows visual inspection of the cutting edge for wear
• Metal open stand storage keeps all 13 pieces organized and readily accessible

Compatibility

Designed for use with standard 3-jaw drill chucks accepting round shanks in the inch measurement system. Suitable for metalworking and multipurpose drilling applications requiring aircraft extension length geometry.

Installation Notes

Installation of these drill bits is performed by machinists, fabricators, HVAC technicians, electricians, and plumbers who require extended reach during drilling operations. Secure the bit firmly in the chuck and verify it runs true before engaging the workpiece. When drilling metals, use cutting fluid to extend bit life and reduce heat buildup, especially in materials harder than mild steel. Wear appropriate eye protection and secure the workpiece before drilling.
