## Long description

DeWalt HSS E Cobalt 7.0 mm drill bits, set of 10 offers a pack of high-speed steel twist drills alloyed with cobalt for improved heat resistance and wear performance. These straight-shank drills are designed for routine metalworking and industrial workshop use, suitable for drilling into harder metals including stainless steel. Supplied as a bulk pack of ten, the set is intended for professional and production environments where durability and consistent hole quality are required.
Advantages
The cobalt-enhanced high-speed steel composition increases hardness at elevated temperatures, reducing wear and extending tool life when cutting tough materials. Straight-shank twist geometry provides reliable centering and compatibility with standard drill chucks and collets. The 7.0 mm diameter gives a common mid-range hole size for metal fabrication, maintenance, and assembly tasks. Supplied in a set of ten, the drills allow for sequential replacement during high-volume work without interruption.
Suitable for
 Drilling mild and hardened steels
 Drilling stainless steel and alloyed metals
 General workshop and industrial maintenance
 Fabrication, assembly and production tasks
Key specifications
 Material: high-speed steel with cobalt alloy (HSS E)
 Diameter: 7.0 mm
 Quantity: set of 10 drill bits
 Shank type: straight shank
 Drill type: twist drill
 Intended use: metalworking, stainless steel, general workshop
How to use
Secure the appropriate drill bit in a compatible drill chuck or collet, ensuring the shank is firmly clamped and the bit runs true. Select a drilling speed appropriate for the material — lower speeds for stainless steel and harder alloys — and apply steady pressure without excessive feed to avoid overheating. Use cutting fluid or lubricant when drilling stainless steel or other heat-sensitive alloys to improve chip evacuation and extend bit life. Withdraw the bit periodically to clear chips when drilling deep holes.
Usage recommendations
For best results when drilling stainless steel, use a slow to medium spindle speed, apply a suitable cutting lubricant, and allow the bit to cool between passes. Replace bits showing significant wear or chipping to maintain hole quality and reduce the risk of workpiece damage.
