## Summary description

DeWalt HSS-E Cobalt drill bits, 6.8 mm diameter, supplied as a bulk set of 10. High-speed steel with cobalt alloy offers improved heat resistance and wear performance for drilling in harder metals. Intended for use with handheld and bench drills for metalworking tasks such as creating holes in steel, stainless steel and other ferrous materials.

## Long description

DeWalt HSS-E Cobalt drill bits, 6.8 mm diameter, set of 10 in bulk supply. These solid high-speed steel bits with cobalt alloy are designed for demanding metalworking tasks and provide greater heat resistance and wear life compared with standard HSS. The 6.8 mm cutting diameter is aimed at straightforward hole creation in steels and other ferrous materials using handheld or bench drills, offering consistent geometry for repeatable performance.
Advantages
The cobalt-enhanced HSS-E construction increases hardness at elevated temperatures, reducing wear when drilling hard or abrasive metals. Precision ground flutes and a uniform point geometry improve chip evacuation and drilling accuracy. Supplied as a set of 10, the bits are convenient for workshop stocking and replacement needs, reducing downtime during metal fabrication or repair work.
Suitable for
Drilling holes in carbon steel
Working with stainless steel and other ferrous alloys
General metal fabrication and repair using handheld or bench drills
Maintenance and industrial workshop use
Key specifications
Material: high-speed steel with cobalt alloy (HSS-E)
Diameter: 6.8 mm cutting diameter
Package quantity: set of 10 bits (bulk)
Tip/point: precision ground geometry for metal drilling
Suitable tool: handheld electric drill and bench drill
How to use
Secure the workpiece and select an appropriate drill speed for the material—lower speeds for harder steels and higher speeds for softer ferrous metals. Install the 6.8 mm bit in the drill chuck and tighten securely. Apply steady pressure, allow chips to clear, and withdraw periodically if drilling deep holes to avoid overheating. Use cutting fluid or coolant when drilling stainless steel or other hard alloys to extend bit life and improve hole quality.
Usage recommendations
Optimize bit life by using suitable cutting fluid, moderate drilling speeds, and intermittent pecking for deep holes. Replace worn bits to maintain hole accuracy and reduce the risk of workpiece damage.
