Miniature hydraulic chuck

The world’s smallest hydraulic chuck for HSK-E25 machine spindles, the Super Slim type of hydraulic chucks (HDC), are tool holders for precision finishing processes in confined areas with drills, reamers, ball mills, end mills, diamond reamers, and grinding tools.
Cutting tools with shank diameters of 3mm or 4mm can be clamped directly and are suited for high speed micro-machining applications in the medical, automotive, aerospace, and electronics industries.
The Super Slim HDC requires a single wrench for clamping and unclamping, an easier solution compared to heat shrink tool holders. Chucks can clamp ultra-small endmills and drills directly, without a reduction sleeve. The external body diameter of the chuck nose is 0.551" (14mm), and a gauge length of 1.575” (40mm). Each tool is precision balanced for speeds up to 60,000rpm and runout accuracy of less than 3µm (0.00012”) at 5xd.
Super Slim HDCs for HSK-E25 machine spindles are available from stock; they are also available for the HSK-E 32 and HSK-E 40 spindle types.
