Tool holders are interface elements that mount the cutting tool to the CNC machine spindle. This category covers shrink-fit holders, ER collet holders, hydraulic holders, BT/BBT/HSK tapers, and custom CNC clamping systems — providing high concentricity and rigidity for precision machining.

Frequently Asked Questions
Common questions about Supporti.
What is the difference between BT, BBT, HSK?
BT: standard Japanese taper; BBT: BT with added face contact (dual contact for high RPM); HSK: German pull-in dual-contact standard (highest RPM and precision).
What is a shrink-fit holder?
A shrink-fit holder expands when heated, the tool is inserted, then cools and shrinks to clamp the tool with high holding force and accuracy.
What are ER collet sets used for?
ER collets allow mounting various tool diameters in a single holder — standard sizes include ER11, ER16, ER20, ER25, ER32, ER40.
When are hydraulic holders used?
On milling and drilling where high surface finish is required — hydraulic holders damp vibration and provide low runout (typically <3μm).
