Hertel C.E96.S13 Cobalt Drill Bit Set 13 Piece

Product Description

The HERTEL C.E96.S13 is a 13-piece cobalt jobber length drill bit set designed for drilling through hard metals, stainless steel, and other demanding materials. Each bit features a 135-degree split-point tip that reduces walking on contact and allows drilling without a center punch in most applications. The straight shank design fits standard keyless and keyed drill chucks. Sizes range from 1/16 inch to 1/4 inch in 1/64-inch step increments, giving technicians and machinists a complete fractional progression in a single case. The gold finish indicates the cobalt M42 or M35 alloy construction and serves as a visual wear indicator during use.

This set is suited for metalworking, HVAC fabrication, plumbing rough-in, and electrical trade work where drilling through harder materials is routine. The jobber length format provides the balance of reach and rigidity most professionals prefer for general-purpose drilling on sheet metal, pipe, structural steel, and fixture work. The included metal storage case keeps bits organized and protected between uses on the job site or in a service van.

Key Features

• Cobalt construction for heat resistance and durability in hard-metal applications

• Size range 1/16 inch to 1/4 inch in 1/64-inch increments for complete fractional coverage
• Straight shank compatible with standard drill chucks
• Gold finish serves as a visual wear indicator and identifies cobalt alloy construction

Compatibility

Designed for use in standard keyed or keyless drill chucks accepting straight shank bits. Suitable for drill presses, hand drills, and right-angle drill attachments used across HVAC, plumbing, electrical, and general metalworking trades.

Installation Notes

Secure the bit firmly in the chuck before drilling and confirm the workpiece is clamped or fixtured to prevent rotation. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and reduce heat buildup. Cobalt bits can be reground but should not be used at speeds exceeding the manufacturer recommendations for the given material and diameter. Always wear eye protection when drilling metal.
