Broca helicoidal 19,5 mm cone Morse MT2 HSS DIN 345 oxidada retificada, comprimento de trabalho 140 mm, comprimento total 238 mm

Precision drilling in tough metals demands a tool that resists wear, stays sharp, and centers accurately under load. This 19.5 mm twist drill bit with Morse taper shank MT2 solves that problem by combining high-speed steel, an oxidized surface, and a ground flute profile for reliable chip evacuation and long service life.

Who is it for

Machinists, metal fabricators, and maintenance technicians who need a dependable large-diameter drill for steel, cast iron, non-ferrous metals, and plastics. It fits drill presses and lathes with an MT2 tailstock or spindle, making it ideal for production drilling, repair work, and general-purpose hole making.

Main features

• Morse taper shank MT2 (DIN 345) for secure, self-locking mounting in matching machine spindles.
• High-speed steel (HSS) body with black oxide finish reduces friction and improves corrosion resistance.
• Ground flutes and 118° point angle deliver accurate centering and smooth cutting in a wide range of materials.
• Right-hand cutting direction with standard spiral flute for efficient chip removal.
• Diameter tolerance h8 ensures consistent hole size for precision work.

Tips

Use cutting fluid when drilling steel or cast iron to extend tool life and improve surface finish. Ensure the Morse taper socket is clean before inserting the bit to prevent slipping. For deep holes, withdraw the bit periodically to clear chips and avoid overheating.
