Multi-purpose High-performance Drilling Machine
YBM-3JR
- Long-selling machine for its reverse rotation and spindle dia.⌀93.
Possible to increase work efficiency and operational safety. - Selectable for spindle rotation speed (A, B and C), and they have 4-speeds range (forward rotation 3-speeds & reverse rotation 1-speed.)
Applicable for various layers and drilling holes. - Spindle Rotation Speed can be chosen in A, B and C speed. Each speed has 3 speeds in positive rotation and 1speed in reverse rotation. Therefore, suitable rotation speed can be applied for various layers and drilling holes.
