Main Product Description
ETP Transmission 706274 is the 25 mm HSK63F variant of the ETP HYDRO-GRIP COMPACT hydraulic expansion chuck family. The verified ETP record specifies D1 25 mm, D2 35 mm, D3 59 mm, gauge length L1 75 mm, L2 49 mm, L3 9 mm, and 56 mm maximum tool insert depth.
This configuration is specified for 480-710 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. It also includes a bore for data carrier and tool-length adjustment by center thread M8 × 1.25. 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 706274 configuration is specified at G 2.5 at 25,000 rpm.
HSK63F Interface
A 75 mm gauge length and internal coolant are matched to the verified HSK63F configuration.
Compatibility & Installation Notes
Confirm the HSK63F machine interface, 25 mm 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 706274 combines the HYDRO-GRIP COMPACT hydraulic clamping system with a 25 mm tool diameter, HSK63F interface, 75 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.
