SHRINKING FOR SPECIAL TOOL HOLDERS
For special tool holders, e.g. tools with a front end that is larger than
the shank, split heat-focusing stoppers are available. The use of split
heat-focusing stoppers requires clearance between the tool head and
the front face of the tool holder. To successfully shrink/release special
tools, it is necessary to observe the following conditions:
▪ Maximal diameter of the cutter BD is 3 x BD1
▪ Ø BD maximum = Ø63 mm (Ø2.48")
(maximum bore Ø of induction unit)
▪ LPR dimension = 70 mm (2.76") minimum
(due to the inductor housing dimension)
▪ LU dimension changes depending on the tool shank diameter BD1

SHRINKFIT OF SPECIAL TOOL HOLDERS
Insert the split heat-focusing stoppers
(see table on previous page) into the location diameter in the inductor
housing.
5 split heat-focusing stoppers covering a tool shank diameter of Ø3-
32 (Ø0.118" to Ø1.26") are available as accessories with the following
capacities:
Ø3-6 (Ø0.118"-0.236"), Ø8-14 (Ø0.314"-0.551"), Ø16-18 (Ø0.629"-
0.708"), Ø20-25 (Ø0.787"-0.984"), Ø32 (Ø1.26").
