Specifications Item Number 625004 Item Description 3/4" OD x 4mm ID Hydraulic Reduction Sleeve Taper HK 3/4 Overall Length 52.5mm Weight 0.1 Sleeve ID 4mm Sleeve OD 3/4" Overview **All images are representative images. Verify specifications before placing orders.** The use of reduction sleeves allows Techniks hydraulic chucks to hold virtually any tool diameter. Reduction sleeves are sealed for coolant-through tooling. Reduction sleeves with I.D. bore diameters of ½”, or 12mm, and larger are manufactured with our patented TTG-594 compound that adds millions of microscopic teeth to the cutting tool connection producing the highest gripping force of any tool holders and reduction sleeve combination. H-Locked Reduction Sleeves working with TTG-594 can unleash the full power of your CNC machine and cutting tool with the strongest gripping connection. Our Proprietary TTG-594 compound is embedded in the I.D. bore of the sleeve, creating millions of microscopic teeth and adding bite to the cutting tool/tool holder connection. Features: I.D. sizes of 1/2″ or 12mm and above are H-LOCKED with our patented TTG-594 compound to create the world’s strongest gripping force of any hydraulic chuck Maximum 0.0001″ T.I.R. Sealed for coolant through applications What Are Reduction Sleeves? Reduction sleeves are designed to allow hydraulic chucks and milling chucks to hold multiple tool diameters. They are sealed for coolant-through cutting tools and can be used in roughing or fine-finishing applications. How Does Reduction Sleeve Work? The reduction sleeve extends the range of large-diameter I.D. holders. During operation, the only thing you need to do is to slide the appropriate sleeve into the tool holder bore. Techniks milling chucks are designed with CoolBLAST coolant grooves in the I.D. bore to direct coolant to the cutting area, to assist with chip evacuation. Techniks reduction sleeves can be used to hold almost any diameter of cutting tool.
