Main Product Description
ETP Transmission 706352 is the 3/4 in SK30 variant of the ETP HYDRO-GRIP COMPACT hydraulic expansion chuck family. The verified ETP record specifies D1 19.05 mm, D2 30 mm, D3 52 mm, gauge length L1 70 mm, L2 50.9 mm, L3 11 mm, and 52 mm maximum tool insert depth.
This configuration is specified for 260-425 Nm transmittable torque, h6 or h7 tool shanks, runout accuracy of ≤ 0.004 mm at 2.5 × D1 (max. 50 mm), and balance degree G 2.5 at 25,000 rpm.
ETP specifies internal coolant for this variant. The HYDRO-GRIP COMPACT family is intended for CNC woodworking operations including semi-roughing, finishing, plunging, contour milling, drilling, reaming, tapping, and thread milling.

Product Highlights
High-Speed Balance
The verified 706352 configuration is specified at G 2.5 at 25,000 rpm.
SK30 Interface
A 70 mm gauge length and internal coolant are matched to the verified SK30 configuration.
Compatibility & Installation Notes
Confirm the SK30 machine interface, 3/4 in tool-shank diameter, h6 or h7 tolerance, approved ETP operating procedure, coolant configuration, tool projection, and spindle limits. Do not substitute a different diameter or interface variant because the HYDRO-GRIP COMPACT family name is the same.
Hydraulic Toolholding with Verified Geometry
ETP Transmission 706352 combines the HYDRO-GRIP COMPACT hydraulic clamping system with a 3/4 in tool diameter, SK30 interface, 70 mm gauge length, and manufacturer-defined torque, runout, and balance specifications.
Exact variant verification matters because related ETP products can share a family name while differing in diameter, interface, torque, dimensions, and numeric product identifier.
