How to Choose the Right Holder
Shank Height (H): Choose based on your machine's tool holder/turret slot size
Tool Height (H3): Must match the H dimension of your SPB Tool (26mm or 32mm)
Example: If you have SPB26-3 tool (H=26mm), select H3=26mm
Must match your SPB Tool's H dimension
HRC≤56 is recommended for best price/performance ratio with newest nano-black coating technology.
