[Features] · The world's No. 1 accuracy : The ultra-precision class is finished to unparalleled precision by assembling world-class technologies. · Runout accuracy (total indicator reading, TIR): 30 μ or less. · Used test bar: Maximum gripping diameter and radius. · It demonstrates fully sufficient power for high precision machining, such as tooling of machining centers and jig borers, etc. · Handle not required: Because a large number of thrust balls are used on the inside, no tools such as handles are required, meaning that attachment and removal of cutting tools can be performed easily with the fingertips.
Keyless type drill chuck allowing drill attachment/detachment with manual rotation alone.

Increased power with hook wrench. Pioneer of integral structure, high-quality.
[Features] · Pioneer of integral structure, high-quality. Runout accuracy: 0.05 mm or less. · Improves work quality. Average of 0.03 mm or less. · An integrated type consisting of an ST shank and chuck. Safer and more reliable. · Increased power with hook wrench. · No loosening, even when the spindle stops suddenly. · Much shorter and more compact. Short Mount Design
Compact integrated shank. Economical and easy to use
[Features] · A compact type in which the L dimension has been made shorter than a conventional drill chuck. · As the shank is integrated, there is no connection or removal. · For high torque machining, the attached wrench can also be used to perform tightening.
