## Long description

Bosch 4 mm HSS drill bit is a high-speed steel twist bit designed for drilling small-diameter holes in metal and a variety of general-purpose materials. The 4 mm diameter provides accurate, clean holes suitable for sheet metal, construction fittings, mechanical assemblies and repair tasks. The bit fits standard drill chucks and is intended for use with hand drills and drill drivers where precise, repeatable metal drilling is required.
Advantages
The HSS construction ensures good heat resistance and cutting durability when drilling through steel and non-ferrous metals. Its standard twist geometry promotes efficient chip evacuation and consistent hole quality. Compact diameter and rigid design help maintain concentricity and reduce wobble in small-diameter drilling operations. The bit’s compatibility with common chucks provides straightforward installation and use across a wide range of drills.
Suitable for
Drilling through thin and medium-thickness sheet metal
Creating pilot holes for screws and fasteners in metal or multi-material assemblies
Repair and maintenance tasks in workshops and on-site
General-purpose drilling in wood, plastics and soft composites when metal-capable bits are preferred
Key specifications
Material: High-speed steel (HSS)
Tip type: Twist drill geometry for general metal work
Diameter: 4 mm
Intended materials: Steel, non-ferrous metals, general-purpose materials
Shank: Straight shank suitable for standard drill chucks
Typical use: Small-diameter precision drilling
How to use
Secure the drill bit in the drill chuck, ensuring it is centered and tightened. Select an appropriate rotational speed for the material being drilled—moderate speeds for steel and higher speeds for softer materials—and apply steady, moderate pressure. Use cutting fluid or lubricant when drilling harder metals to reduce heat buildup and extend bit life. Withdraw the bit periodically to clear chips and prevent clogging of the flutes.
Usage recommendations
When drilling steel or other hard metals, start with a slower speed and use cutting oil; maintain straight alignment and steady feed pressure to achieve accurate holes and prolong the bit’s service life.
