Shrink Fit Machines
From a benchtop unit for your first shrink fit holders to a fully automated cell, every HIPPSC machine heats, clamps and cools in seconds.
How shrink fit works
Shrink fit uses heat instead of mechanical clamping. The result is the tightest, most concentric grip you can put on a carbide tool.
An induction coil heats the holder nose in seconds. The bore expands just enough for the tool shank to slide in.
Drop in the carbide tool and set the length. No collets, nuts or wrenches.
Air or coolant cooling shrinks the bore back onto the shank for a 360° grip with no moving parts.
The lineup
Compact benchtop shrink fit with quick-change coils and QR tool recognition.
From $7,685
Fits where a full-size machine can't, without giving up coolant-cooled speed.
Pricing on request
15 kW of induction heating and coolant cooling for big diameters and heavy roughing tools.
Pricing on request
Scans the holder, sets itself up, and plugs into the MES / ERP your shop already runs.

Job shop · first shrink fit
Benchtop footprint, single-phase 220 V power and quick-change coils for 3–32 mm shanks. Sits on any workbench next to your machines.
Our pick: U7 ProProduction shop · tight floor
Coolant cooling gets holders back to the spindle in 15–35 s, from a 700 × 520 mm footprint that fits where a full-size machine can't.
Our pick: F6i ProHeavy machining · large holders
15 kW and three quick-change coils up to a 68 mm bore handle holders up to 62 mm OD, with coolant cooling to keep up with volume.
Our pick: F15i ProAutomated cell · lights-out
Scan-to-identify sets heating parameters automatically, low-temperature control protects holder hardness, and MES / ERP interfaces connect it to your tool room.
