## Summary description

High-speed steel (HSS) twist drill bit DeWalt DT5558, 10.5 mm diameter, designed for general-purpose metal and wood drilling. Part of the HSS Extreme line, it provides durable cutting performance and precise hole forming for workshop and construction use. Suitable for handheld drills and drill presses when drilling medium-hard materials.

## Long description

DeWalt DT5558 HSS Extreme drill bit with a 10.5 mm diameter is a high-speed steel twist bit intended for general-purpose drilling in metal and wood. Designed as part of the HSS Extreme line, this bit balances hardness and toughness to deliver consistent hole quality and reliable cutting life in workshop and construction environments. It is compatible with handheld drills and drill presses and is intended for use on medium-hard materials where precise, straight holes are required.
Advantages
The HSS construction provides heat resistance and wear performance during continuous drilling. A precisely ground tip promotes accurate centring and reduces walking on flat surfaces, helping to maintain hole position without the need for pilot marks. The 10.5 mm diameter offers a balance between clearance and strength for medium-sized holes, while the twist geometry ensures efficient chip evacuation to minimise clogging and overheating. The overall design suits repeated use in production or repair tasks.
Suitable for
Drilling holes in mild and medium-hard steel
Woodworking tasks requiring clean through-holes
Use with handheld electric drills and drill presses
Workshop maintenance and general construction drilling
Key specifications
Material: high-speed steel (HSS)
Diameter: 10.5 mm
Tip style: precision-ground twist point for accurate centring
Suitable materials: metal (mild/medium hardness), wood
Tool compatibility: standard drill chucks for handheld drills and drill presses
How to use
Select an appropriate chuck or collet and secure the 10.5 mm drill bit firmly. Mark the drilling point and, for best accuracy on flat metal surfaces, use a centre punch before starting. Begin drilling at a moderate speed and apply steady, even pressure; for metal, use cutting lubricant to reduce heat and extend bit life. Periodically withdraw the bit to clear chips and allow cooling during longer holes. After completion, retract the bit and inspect the hole for burrs, deburring as required.
Usage recommendations
For prolonged life and consistent results, match drill speed and feed to the material: higher speeds for softer woods, reduced speeds with lubrication for steel. Store the bit in a protective case or rack to prevent tip damage and maintain cutting performance.
