BIG KAISER, a global leader in premium high-precision tooling systems and solutions for the metal-working industries, launches the world’s smallest hydraulic chuck for HSK-E25 machine spindles, thus completing its extensive range of BIG KAISER Super Slim hydraulic chucks.

The Super Slim type of Hydraulic Chucks (HDC) are the perfect tool holders for precision finishing processes in confined areas with drills, reamers, ball mills, end mills, diamond reamers and grinding tools. The wide variety of clamping diameters and projections are ideally suited for practically all applications in the automotive, aerospace, medical, die & mold segments.

BIG KAISER designed the Super Slim HDC to require only a single wrench for clamping and unclamping. These chucks can clamp ultra small mills and drills directly, without needing a reduction sleeve, down to a diameter of 3mm. When clamping diameters of 3mm, the external diameter of the chuck nose is a mere 14mm, and at a length of 90 mm the diameter is 25 mm – meaning that interference contours should no longer pose a problem.

“Our HSK-E25 tool holder lineup now includes BIG KAISER’s high precision, low runout, hydraulic chucks,” says Peter Elmer, CEO of BIG KAISER. “These ultra-precise hydraulic chucks, with their extremely slim design, are perfectly suited for high precision finish milling work on ultra-high speed spindles on machines with small work envelopes.”

The Super Slim HDCs for the HSK-E25 machine spindles are available now; also available for the HSK-E 32/40/63 and BBT 30/40/50 spindle model lines.
