## Summary description

Set of DeWalt cobalt cylindrical drill bits, model DT4942, containing ten 10 mm bits designed for drilling metal.

## Long description

Set of DeWalt cobalt cylindrical drill bits, model DT4942, containing ten 10 mm bits designed specifically for drilling metal. Each bit is manufactured from a cobalt alloy to improve heat resistance and maintain cutting performance during prolonged metalworking. The cylindrical shank design ensures compatibility with standard three-jaw chucks and bench drills commonly used in workshops and industrial environments.
Advantages
The cobalt construction increases wear resistance and preserves cutting geometry at high temperatures encountered when drilling stainless steel and other hard alloys. A precisely ground tip provides consistent centring and reduced walking on flat workpieces, while the uniform 10 mm diameter across the set simplifies tool selection for repetitive tasks. The cylindrical shank offers stable clamping and straightforward replacement in drill chucks.
Suitable for
Drilling holes in steel, stainless steel and other ferrous metals
Workshop and industrial metal fabrication
Maintenance and repair tasks requiring consistent 10 mm holes
Use with hand-held drills and bench-mounted drill presses equipped with three-jaw chucks
Key specifications
Material: cobalt alloy for high heat resistance
Shank type: cylindrical shank for use with standard chucks
Diameter: 10 mm
Quantity: 10 pieces
Intended application: drilling metal, including hard and stainless steels
How to use
Select an appropriate cutting speed and apply steady, moderate feed pressure when drilling metals to avoid overheating. Secure the workpiece firmly in a vise or fixture before starting. Fit the cylindrical shank into the drill chuck and tighten securely. Use cutting fluid or coolant when drilling stainless steel or other heat-sensitive alloys to extend bit life and improve chip evacuation. After use, clean chips from the flutes and store the bits in a dry place to prevent corrosion.
Usage recommendations
For best results when drilling stainless steel or hardened materials, run the drill at lower speeds with ample cutting fluid and allow the bit to cool periodically; replace bits showing significant wear to maintain hole quality and operator safety.
