ETP HYDRO-GRIP COMPACTHSK63FG 2.5 / 25,000 rpmSKU 705681
For compatible HSK63F CNC woodworking systems and 3/4 in tool shanks within the manufacturer-specified h6 or h7 tolerance.
Main Product Description
ETP Transmission 705681 is the 3/4 in HSK63F 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 75 mm, L2 49 mm, L3 30 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. 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 705681 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, 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 705681 combines the HYDRO-GRIP COMPACT hydraulic clamping system with a 3/4 in 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.
