Provide guaranteed precision of 0.0002" at four inches out. A precision grip hydraulic chuck is the most accurate toolholder for finishing end mill applications. It maximizes the use of each cutting edge of an end mill tool. Hydraulic chucks provide for reaming, gun drilling and boring operations where finish and tool life specifications cannot be accomplished economically with other tools and processes.
Positive stop actuating set screw provides optimal gripping forces on the end mill cavity.
Holders are not through coolant capable.
Straight shank tooling for extended length machining is less costly than purchasing custom holders. The outside diameter allows close cutting operations where space is limited.
Extensions hold double end mill
