Broca helicoidal RUKO SPB-DIN338-HSSCo8-TiAlN-Ø9,9mm

Twist drill bit with 9.9 mm diameter, manufactured from high-speed steel with 8% cobalt and TiAlN coating for high heat and wear resistance. The split point design ensures self-centering and reduces walking on the workpiece.

Advantages

Fully ground from HSS Co 8 for high hardness and toughness. TiAlN coating provides excellent thermal stability and extends tool life, especially in demanding applications. The 130° point angle and split point geometry deliver precise centering and efficient chip evacuation.

Suitable for

• Alloyed and unalloyed steel up to 1100 N/mm²
• Stainless steel
