## Summary description

DeWalt DT5544 is a 4.2 mm HSS drill bit designed for metalworking and general drilling tasks. Made from high-speed steel (HSS), it provides durability and consistent cutting performance for through-holes and pilot holes in steel, iron and non-ferrous metals. Suitable for workshop and professional use with hand drills and drill presses.

## Long description

DeWalt DT5544 HSS 4.2 mm is a high-speed steel (HSS) drill bit engineered for metalworking and general drilling tasks. Intended for making through-holes and pilot holes in steel, iron and non-ferrous metals, this 4.2 mm diameter bit is suitable for both handheld drills and drill presses. The solid HSS construction offers wear resistance and steady cutting performance for workshop and professional environments.
Advantages
The HSS material provides heat resistance and sustained hardness during drilling, reducing premature dulling when cutting metal. The 4.2 mm diameter delivers precise hole size control for pilot holes and small through-holes. The standard flute geometry facilitates effective chip removal and stable drilling, while compatibility with common drill chucks makes it useful across a range of machines.
Suitable for
 Drilling pilot holes in steel and iron before tapping or fastening
 Creating small through-holes in aluminium and other non-ferrous metals
 Workshop tasks with handheld drills and drill presses
 General metal fabrication and maintenance work
Key specifications
 Material: High-speed steel (HSS)
 Diameter: 4.2 mm
 Tip/Point: Standard 118° (typical for general purpose metal drilling)
 Suitable materials: Steel, iron, aluminium and other non-ferrous metals
 Intended use: Through-holes and pilot holes
 Drive compatibility: Standard drill chucks for handheld drills and drill presses
How to use
Mark the drilling point and secure the workpiece to prevent movement. Select appropriate cutting speed based on material thickness and hardness; use lower speeds for harder steels and higher speeds for softer non-ferrous metals. Apply steady, moderate feed pressure while keeping the drill perpendicular to the surface. For deeper holes or harder materials, periodically withdraw the bit to clear chips and reduce heat buildup. Use cutting fluid when drilling steel to extend bit life and maintain cutting performance.
Usage recommendations
Always wear appropriate eye and hand protection when drilling. Inspect the bit before use for signs of damage or wear and replace when cutting performance deteriorates. For precision holes, pilot and finish with correct speeds and steady feed; for prolonged metal drilling, use cutting lubricant and controlled speeds to preserve the HSS edge.
