MILLING CHUCKS
NEW Hi-POWER MILLING CHUCK
MEGA DOUBLE POWER CHUCK
Clamping Range: Ø.500"-1.500" (12-50mm) For heavy-duty end milling. Complete contact of nut and body achieves high rigidity, close to that of an integral tool to ensure heavy cutting without chatter. Notch-free nut makes high speeds possible.
Clamping Range: Ø.500"-1.500" (12-42mm) For heavy-duty end milling.
The thick wall body and high gripping force ensures high rigidity and stable performance. Fine and narrow slits in the body make the clamping part deform properly to ensure even and strong gripping force and stable runout. Now available in BIG-PLUS as standard. See PJC collets on pg. 9 for reduction and coolant delivery options.
New HSK inch sizes are now available as a standard item.

Powerful Clamping Force Deflection test to compare with other manufacturer’s milling chuck proves that the MEGA DOUBLE POWER CHUCK has achieved 1.4 times higher rigidity.
Decreased runout accuracy and insufficient gripping force.
No escape route for oil film which causes processing failure. Remaining oil film reduces gripping power and may cause slip.
