## Long description

Drill bit for metal Smart HSS cylindrical 4.2 mm set of 10 are high-speed steel (HSS) twist drill bits designed for drilling holes in ferrous and non-ferrous metals.

Key specifications
Material: high-speed steel (HSS)
Diameter: 4.2 mm
Shank type: cylindrical (straight) shank compatible with standard chucks
Type: twist drill bit for metal
Quantity: set of 10 pieces
How to use
Select a drill with a compatible chuck and secure the cylindrical shank of the 4.2 mm HSS bit tightly in the chuck. Mark and clamp the workpiece to prevent movement, and use cutting fluid or coolant when drilling harder metals to reduce heat and extend bit life. Start at a low speed to establish the hole, then increase speed as appropriate for the material. Apply steady, moderate pressure and periodically clear chips from the hole to maintain cutting efficiency.
Usage recommendations
For best results, use appropriate drill speeds for the material being drilled and apply cutting fluid when working with stainless steel or other hard alloys. Replace bits when they show signs of wear, chipping, or excessive vibration to maintain hole quality and prevent damage to the workpiece or drill.
