## Summary description

DeWalt DT4944 HSS-E Cobalt drill bits, 10.5 mm diameter, pack of 5. High-speed steel with cobalt alloy (HSS-E) for improved heat resistance and durability when drilling hard materials. Designed for metalworking and industrial use where longer tool life and consistent hole quality are required. Suitable for hand and machine drilling.

## Long description

DeWalt DT4944 HSS-E Cobalt drill bits, 10.5 mm diameter, pack of 5, are high-speed steel cutting tools alloyed with cobalt for improved hardness and heat resistance. These drill bits are intended for drilling metal and other hard materials where sustained cutting performance and dimensional stability are required. The set supports both hand-held and machine drilling and is supplied as five identical diameter bits to cover repetitive or multiple-hole tasks.
Advantages
The HSS-E cobalt material provides better wear resistance and higher hot hardness than standard high-speed steel, reducing tool wear during prolonged use on hardened steels and stainless materials. The 10.5 mm diameter offers a typical mid-size hole useful in many metalworking applications, while the precision-ground flutes and tip geometry maintain consistent cutting performance and hole quality. Supplied in a pack of five, the set reduces downtime by providing immediate replacements when bits blunt or break.
Suitable for
 Drilling steel, stainless steel and other ferrous metals
 Fabrication and maintenance workshop drilling tasks
 Machine and hand-held drilling operations
 Repeated-production holes where consistent diameter is required
Key specifications
 Material: high-speed steel with cobalt alloy (HSS-E)
 Diameter: 10.5 mm
 Pack quantity: 5 pieces
 Intended use: metalworking and industrial drilling
 Shank style: straight shank suitable for standard chucks
How to use
Secure the workpiece and select an appropriate drill speed for 10.5 mm HSS-E bits and the material being drilled. Clamp the drill bit in a suitable chuck and align perpendicular to the work surface. Use cutting fluid or coolant when drilling stainless steel or hardened materials to reduce heat and extend tool life. Apply steady, moderate feed pressure; back off periodically to clear chips if drilling deep holes. Replace a worn or damaged bit from the pack to maintain hole quality.
Usage recommendations
For best results when drilling stainless steel and other heat-sensitive alloys, use cutting fluid, keep drill speed moderate to low, and allow the bit to cool periodically. Inspect bits for wear and replace with another from the set when cutting performance declines. Store the pack in a dry place to avoid corrosion.
