Drill bit for metal Abraboro 3.8 mm HSS-R DIN 338 black
Abraboro drill bit for metal, 3.8 mm diameter, is a solid twist drill made of HSS-R high-speed steel and manufactured to DIN 338 dimensions. The black finish reduces glare and provides basic surface protection. Designed for drilling steel and other metallic materials, this 3.8 mm drill bit can be used in hand-held drills, drill presses and milling machines where precise 3.8 mm holes are required for general metalworking, repair and maintenance tasks.
The HSS-R material provides good hardness and heat resistance for metal drilling operations. Manufacturing to DIN 338 ensures consistent geometry and compatible shank and flute dimensions for widespread tool holders. The black finish offers minor corrosion resistance and reduced reflection during use. The 3.8 mm diameter offers a precise hole size for pilot holes, fastening points and small through-holes in a variety of ferrous and non-ferrous metals.
Secure the drill bit in the drill chuck so the shank is held firmly and runout is minimised. Select an appropriate spindle speed and cutting fluid for the material being drilled; lower speeds and coolant are recommended for harder steels. Use steady feed pressure and keep the drill perpendicular to the workpiece to maintain hole accuracy. Retract periodically to clear chips and avoid overheating. After each use inspect and, if necessary, resharpen the HSS-R tip to restore cutting performance.
Use cutting fluid or coolant when drilling hard or thick metal to extend tool life. For precise 3.8 mm holes, pre-centre with a centre punch and maintain correct speed and feed; resharpen HSS-R bits when dull rather than applying excessive force.
