## Long description

KWB 048640 is a single 4 mm multipurpose drill bit made from hard metal (tungsten steel) with a total length of 75 mm and a cylindrical shank. It is intended for general drilling tasks where a carbide tip provides enhanced wear resistance and cutting performance. The bit is compatible with handheld drills and drill presses and is designed to deliver precise holes for maintenance, DIY and light professional applications.
Advantages
The carbide (tungsten steel) construction increases resistance to wear and heat compared with standard high-speed steel bits, supporting longer life when drilling abrasive materials. The 4 mm diameter and 75 mm total length balance control and reach for common drilling depths. The cylindrical shank ensures compatibility with standard drill chucks and simple mounting in both handheld and bench drilling equipment.
Suitable for
Drilling small-diameter holes in metal sheets and thin metal parts
Drilling in masonry and concrete when a carbide tip is required
Precision holes in wood and composite materials
Maintenance, repair and light professional workshop tasks
Key specifications
Diameter: 4 mm
Material: carbide (tungsten steel)
Total length: 75 mm
Shank type: cylindrical shank
Pack quantity: single piece
How to use
Select an appropriate drilling speed and drill bit holder for a 4 mm cylindrical shank. Secure the workpiece and, if drilling metal or masonry, use steady pressure and consistent feed to avoid overheating the tip. For handheld operation keep the drill perpendicular to the surface to obtain a straight hole; for bench drilling use the machine’s guides for alignment. Withdraw the bit periodically when drilling deep holes to clear chips and reduce heat buildup.
Usage recommendations
Use cutting fluid or cooling when drilling metal to extend bit life; when drilling masonry start with a pilot point suitable for carbide and avoid hammer action unless the bit and machine are rated for percussion drilling.
