## Summary description

Cobalt HSS E drill bit by DeWalt, model BD-DT4924, 4.0 mm diameter. High-speed steel with cobalt alloy designed for enhanced heat resistance and durability when drilling hard metals. Suitable for use in hand drills and drill presses for metalworking tasks, maintenance and repair, and professional workshop applications requiring precise 4.0 mm holes.

## Long description

DeWalt Cobalt HSS E drill bit, 4.0 mm diameter, is a high-speed steel cutting tool alloyed with cobalt to improve heat resistance and wear life when drilling hard metals. Engineered for metalworking, maintenance and repair, and professional workshop use, this 4.0 mm drill bit provides consistent hole quality and edge retention in demanding conditions. The bit is suitable for both hand-held drills and drill presses, offering the rigidity and cutting performance expected from DeWalt metalworking accessories.
Advantages
The cobalt-enriched HSS composition increases hardness at elevated temperatures, reducing premature dulling when drilling stainless steel, alloy steels and other tough materials. A precise 4.0 mm diameter and well-ground point geometry help start holes accurately and maintain concentricity, while the robust construction provides longer service life compared with standard HSS bits. The bit’s design balances cutting speed and durability for repeated metal drilling tasks.
Suitable for
Drilling 4.0 mm pilot and through holes in stainless steel and alloy steels
Workshop and maintenance metalworking tasks
Hand drills and drill press operations requiring precise metal holes
Professional repair work on machinery, automotive and fabrication projects
Key specifications
Material: high-speed steel with cobalt alloy
Diameter: 4.0 mm
Intended use: metal drilling (including stainless and alloy steels)
Compatible tools: hand drills and drill presses
Point geometry: ground for accurate starts and improved centering
How to use
Secure the workpiece firmly and mark the drilling position. Use an appropriate drill speed and cooling lubricant when drilling hard metals to reduce heat buildup and extend tool life. Start with a low feed until the bit locates the mark, then apply steady pressure and consistent speed. Clear chips periodically to avoid clogging the flutes and allow the bit to cool between extended cuts. After use, clean and store the bit to prevent corrosion and preserve sharpness.
Usage recommendations
For best results on stainless and high-alloy steels, use cutting fluid and moderate speed; avoid excessive feed pressure that can cause premature breakage. Inspect the bit before use and replace when wear reduces cutting performance.
