USED LYNDEX 3/16" END MILL HOLDER

The Lyndex CAT 40 End Mill Holder is a precision tool holder designed for CNC machining applications, specifically engineered to secure cutting tools with a 3/16 inch shank diameter. This holder utilizes the CAT 40 taper standard, which is widely compatible with V-flange machining centers. Technical specifications for Lyndex CAT 40 series holders typically include a taper ground to AT3 specifications or better to ensure maximum spindle contact and minimize vibration. The unit features a precision-ground inner bore intended to provide low total indicated runout for enhanced tool life and accuracy during milling operations. The construction is generally made from high-quality alloy steels, such as 4340 nickel chrome, hardened to maintain rigidity and durability under heavy side loads. These holders often support through-spindle coolant or specialized coolant options like Coolblast and Coolflex to manage heat at the cutting interface. Additionally, many Lyndex holders are balanced for high-speed operation, frequently reaching up to 20,000 RPM, to meet the requirements of modern high-performance machining environments. The year of manufacture for this specific unit is not available.
