Big Kaiser has launched what it says is the world’s smallest hydraulic tool-holding chuck for HSK-E25 machine spindles. Offered in the UK by Tamworth-based Industrial Tooling Corporation Ltd (www.itc-ltd.co.uk), the new HDC line completes the range of Big Kaiser Super Slim hydraulic chucks.

Super Slim HDC chucks are designed for precision finishing processes in confined areas with drills, reamers, ball mills, end mills, diamond reamers and grinding tools.

Only a single wrench is required for clamping and unclamping. Furthermore, the chucks can clamp tools down to 3mm in diameter without the need for a reduction sleeve.

When clamping 3mm diameters, the external diameter of the chuck nose is just 14mm. Moreover, at a distance of 90mm from the nose, the diameter is only 25mm.

This slender design means that interference should no longer pose a problem. Super Slim HDC chucks are available for HSK-E 32/40/63 and BBT 30/40/50 spindle variants.
