RUKO STB-HSS-TiN-SP broca escalonada 6,0-32,0 mm, 14 escalones, HSS recubierto de nitruro de titanio

Step drill bit made of high-speed steel with titanium nitride coating, covering diameters from 6.0 to 32.0 mm in 14 steps of 2 mm increments. The TiN coating provides high heat resistance up to 600°C and reduces friction for longer tool life.

Advantages

Spiral flute design with split point geometry ensures precise centering and smooth chip evacuation. The 3-flat shank prevents slipping in the drill chuck. Suitable for drilling, deburring, and reaming in thin materials up to 4 mm thick.

Suitable for

• Sheet metal
• Non-ferrous metals
• Plastics
• Thin steel sheets
