## Summary description

Abraboro HSS cylindrical drill bits for metal, 4.2 mm diameter, set of 10 (MPN AB00010421). High-speed steel construction suited for drilling steel and other metals. Cylindrical shank design for standard chucks and drill holders. Intended for workshop, maintenance, and metalworking tasks where consistent 4.2 mm holes are required.

## Long description

Abraboro HSS cylindrical drill bits for metal, 4.2 mm diameter, set of 10 are designed for routine metal drilling tasks in workshops and maintenance environments. Made from high-speed steel (HSS), the 4.2 mm bits provide a balance of hardness and toughness for drilling into various ferrous and non-ferrous metals. The cylindrical shank fits standard drill chucks and holders, ensuring straightforward installation and stable rotation during use.
Advantages
The HSS material offers good heat resistance and wear performance for general-purpose metalworking. Supplying ten identical 4.2 mm bits ensures consistent hole size across multiple operations and reduces downtime for tool changes. The cylindrical shank design is compatible with common drills and bench machines, and the compact diameter is suitable for precise, controlled drilling in sheet metal, plates, and smaller components.
Suitable for
 Drilling holes in steel, stainless steel, aluminum and other metals
 Workshop and maintenance drilling tasks
 Production runs requiring consistent 4.2 mm hole diameter
 Repair and fabrication work on metal parts and components
Key specifications
 Material: high-speed steel (HSS)
 Tip/point type: standard twist drill geometry for metal
 Diameter: 4.2 mm
 Shank type: cylindrical (straight) shank for standard chucks
 Quantity: set of 10 identical drill bits
How to use
Select an appropriate cutting speed and feed for the material being drilled, clamp the workpiece securely, and mount the 4.2 mm cylindrical shank in a compatible drill chuck. Begin drilling at low speed to establish the hole, then increase speed as appropriate while applying steady, even pressure. Use cutting fluid or coolant when drilling harder metals to reduce heat and extend tool life. Withdraw the bit periodically to clear chips and prevent clogging.
Usage recommendations
For optimal performance, pre-drill with a center punch on sheet or curved surfaces to prevent walking, use cutting fluid when working with stainless steel or high-strength alloys, and replace bits from the set when signs of wear—such as increased force required, chatter, or poor hole finish—are observed.
