•Chip load distributed evenly along cutting edge of tool which results in longer tool life. •Constructed of double tempered Tool Steel for exceptional durability and cycle life. With proper use, toolholder life should exceed that of standard end mill holders. •Short projections are possible because no mechanical clamping devices are used. This results in greater rigidity and resistance to bending. •Simple and fast to use. The total time elapsed to remove one cutting tool and insert another is less than 10 seconds. •Through-spindle coolant capability •The use of Heat Shrink Tooling allows for greater speeds and feeds, better finishes, increased tool life, and increased productivity due to its High Speed Machining capability and simplicity of use.
