• Inside Diameter: (d) .1250”

• Bottom Diameter: (D1) 3/4"

• Top Diameter: (D2) 25mm

The reduction sleeves are designed to fit with the ETP Toolholders.

They are specially suited for high precision clamping of cylindrical tool shanks per DIN 6335 form HA, HB and HE, as well as tool shanks per DIN 1835 form B, C, D and E.

The special design of the reduction sleeves allows efficient use of coolant through cutting tools. 

• Standard version HS suited for internal cooling
• Metal-to-metal seal for cutting tools with internal coolant channels.
• HS-CF version suited for peripheral cooling
• The coolant flush reduction sleeves HS-CF can be used for peripheral cooling due to their coolant channels.
• Accurate precision
• High runout accuracy < 3 μm.
• High flexibility
• Clamping of different tool shank diameters. 12, 20, 25, 32 mm and 1/2", 3/4", 1", 1 1/4".
• Power increase 
• When using reduction sleeves the transmittable torque is increased.
