Tool
For Maximum Gripping Power
with Exceptional Concentricity
Gripping Force 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.
Gripping Force
Constructed with durable tempered Tool Steel for exceptional durability
Optional Back-
UpScrew and cycle life. No mechanical clamping devices are used. With proper use,
toolholder life should exceed that of standard End Mill holders.
Tool is gripping 360°, along the entire length of the bore resulting in an
evenly distributed clamping force and increased concentricity.
Improved balance design with no moving pieces. Low centrifugal forces due
to low holder mass.
Technical Specifications
Standard holders have 4.5° angle nose for compatibility with most heat
shrink machines.
Balanced to G 2.5 at up to 25,000 rpm, refer to charts for each taper size.
Available from stock in BT, CAT and HSK Tapers. Also available from stock in
short and extended lengths. Other lengths, medium and extra-long, available
upon request.
Standard with AD/B coolant entry.
Concentricity of less than .0001” with tool shrunk in holder.
Coolant Options
Coolant through holders require no special backup screws or seals. The
interference fit between the ID of the toolholder and cutting tool shank
creates the seal, preventing the coolant from flowing anywhere else except
through the cutting tool. Coolant grooves and coolant porting also available.
