## Long description

Smart HSS cylindrical drill bits for metal, 4.2 mm diameter, set of 10 pieces. These high-speed steel (HSS) bits are engineered for drilling steel and non-ferrous metals and are compatible with hand drills and drill presses. The cylindrical shank design provides a secure fit in standard chucks, while the 4.2 mm cutting diameter meets requirements for precision holes in fabrication, repair and mounting tasks.
Advantages
The HSS material offers good wear resistance and heat tolerance during continuous drilling in metal. A consistent ground geometry ensures repeatable hole size and reliable centering when used with appropriate pilot marks or punches. Supplied as a set of ten, the bits provide quick replacement and reduce downtime on repetitive jobs. The cylindrical shank fits most standard drill chucks and allows use in both portable and bench-mounted drilling equipment.
Suitable for
Drilling holes in mild and medium carbon steel
Working with non-ferrous metals such as aluminum, brass and copper
Fabrication, repair and mounting tasks requiring 4.2 mm holes
Use in hand drills and drill presses for workshop or maintenance work
Key specifications
Material: high-speed steel (HSS)
Shank type: cylindrical (straight) shank compatible with standard chucks
Cutting diameter: 4.2 mm
Quantity: set of 10 identical bits
Typical applications: steel and non-ferrous metals
How to use
Mark the drilling point and, where necessary, create a center punch indent to improve bit tracking. Secure the workpiece in a vise or with clamps to prevent movement. Fit the 4.2 mm HSS bit into the drill chuck and tighten securely. Use a suitable drill speed for metal drilling (moderate to high speeds for small diameters) and apply steady pressure; allow the bit to cut without forcing. For prolonged drilling or harder materials, use cutting fluid or lubricant to reduce heat and improve tool life. Retract occasionally to clear chips when drilling deeper holes.
Usage recommendations
Use appropriate personal protective equipment, including safety glasses and gloves. Match drill speed and coolant use to the metal type: lower speeds and consistent lubrication for harder steels, higher speeds for softer non-ferrous metals. Inspect bits for wear or chipping before use and replace worn bits to maintain hole quality and operator safety.
