Toolholders

Somma Tool Co. announces the development of a broach toolholder that is reportedly uniquely interchangeable among any style of ER collet chuck. The compact, adjustment-free, offset, rotary broach toolholder will thread to an existing ER (16, 20, 25 and 32) collet chuck and features a built-in 1-degree wobble cutting edge for offset rotary broaching.

With the SCHUNK TENDO Slim 4ax hydraulic expansion toolholder, it is possible to combine the complete outside geometry of heat shrinking mountings with SCHUNK hydraulic expansion technology. The slim mounting makes it suitable for use in series production, particularly in the automotive industry.

The PGU 9500 automatic clamping unit is the newest member of REGO-FIX Tool Corp.’s well-established powRgrip family of toolholding. The system is smaller in size, ergonomic, energy efficient and practically maintenance free.

Kennametal Inc. says the bending moment of KM4X is substantially higher than any tooling interface available on the market, superior even to Kennametal’s own KM design. Kennametal has announced the KM4X tooling family has gained a 63 mm sibling, one aimed at a broader machine tool platform and, therefore, greater availability to the machining community.
