RUKO SPB-DIN338 HSS-G špirálový vrták krížový brús, 12,4 mm

Twist drill bit with split point for precise centering and reduced feed pressure, manufactured from solid HSS-G (high-speed steel, ground) to DIN 338. The 135° split point ensures self-centering without center punch, making it ideal for stationary and hand-held drilling in a wide range of materials.

Advantages

Precision ground from solid for high accuracy and long tool life. The split point design minimizes walking and requires less feed pressure, improving hole quality and operator comfort. Bright finish provides a clean surface and good chip evacuation.
