Features

• High precision - the runout is within 0.002" and, even on average, within 0.0012".
• CAT-V and BT -Flange Models for Machining Center - the shank and the chuck body are combined through taper.
• Morse Taper and Straight Shank models - the shank and the chuck body are integrated into one. These one-unit types are safe in operation, having no possibilities of the chucks being loosened from the shanks.
• Also, this unification of the shank and the chuck body makes the length from the guage line to be shorter, which will enable even the smaller machine tools to have their working space efficiently utilized.
• For chucking a drill, tighten the sleeve by hands and then re-tighten the sleeve with the attached spanner, which will make the gripping torque three times stronger than the tightening by hands only. Also this re-tightening with the spanner prevents loosening of the sleeve at an emergency stoppage of the main spindle and thus no falling-down of the drill bit from the chuck.
• The jaws are made of chrome-molybdenum steel with proper heat-treatment and sub-zero treatment and have a long life with precision.
