Versatility - Suitable for portable or stationary drilling of high alloy content steels and metals with a tensile strength up to 1100n/mm²
No Slip Shank - Spin proof three sided shaft for optimal grip in drill chuck
Tough Core - Increasing the central Core thickness towards the chuck improves fracture stability, particularly in free hand use.
