No collets. No screws. No hydraulics. Just thermal expansion — a single-piece clamp holding sub-3-micron runout at 30,000 RPM.

How it works

Induction heats the holder's bore in seconds. The steel expands, the tool drops in, and as it cools the bore contracts around the shank — a shrink of microns, a grip of tons. One piece of steel. Zero moving parts.

Why it wins

Collets and hydraulics introduce joints, and joints introduce wobble. Shrink fit is a monolithic interface — better concentricity, tighter balance, longer tool life. Engineered for 3-, 4-, and 5-axis work where microns decide the part.

What you get

Less vibration at the edge. Cleaner surface finish off the spindle. Faster tool swaps between jobs. Shrink fit is the holder of choice when you're milling at speed, drilling at depth, or finishing to spec — and you can't afford to do it twice.
