HS REDUCTION SLEEVEINCH TO INCHINTERNAL COOLINGSKU R1919.15882
For compatible ETP hydraulic toolholding arrangements accepting a 3/4 in (19.05 mm) reduction sleeve body and a 5/8 in (15.875 mm) cylindrical tool shank.
Main Product Description
ETP Transmission R1919.15882 is an HS inch-to-inch reduction sleeve for CNC woodworking. The verified ETP geometry reduces holder diameter D2 19.05 mm (3/4 in) to tool diameter D1 15.875 mm (5/8 in), with outside diameter D3 25 mm.
The exact sleeve dimensions are L1 50 mm, L2 48 mm, and L3 4 mm. These dimensions identify the submitted sleeve variant and must not be borrowed from adjacent HS sleeve rows.
ETP specifies this sleeve as an inch-to-inch reduction sleeve for internal cooling. It is used to adapt a smaller cylindrical tool shank to a compatible hydraulic toolholding bore while retaining the ETP sleeve interface.

Exact L1/L2/L3 dimensions are 50 / 48 / 4 mm for SKU R1919.15882.
Compatibility & Installation Notes
Confirm the receiving hydraulic holder accepts the verified 3/4 in (19.05 mm) sleeve diameter and that the tool shank is 5/8 in (15.875 mm). Maintain the ETP-specified internal-cooling arrangement and do not substitute adjacent HS sleeve sizes with similar outside dimensions.
Exact HS Reduction Geometry for CNC Toolholding
ETP Transmission R1919.15882 provides a verified 3/4 in-to-5/8 in inch-to-inch reduction in the HS sleeve format, with D3 25 mm and L1 50 mm.
Exact SKU selection is critical because ETP publishes multiple HS body sizes and tool diameters with closely related part-number patterns but different dimensional rows.
