Reach deeper, hold tighter, run truer. HIPPSC shrink fit extension holders deliver sub-3-micron runout accuracy in the long-reach and deep-cavity work where ordinary holders flex, chatter, and chase tolerances.
The slim, balanced nose profile clears tight walls and steep pockets, while full-contact thermal clamping grips your tool with uniform force around the entire shank; no setscrews, no collet slip, no runout creep.
Ordinary holders flex and chase tolerances in deep cavities. A monolithic thermal clamp keeps cuts true, kills chatter, and protects your edge on every projection.
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.
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.
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.
