Shell Mill Holder: CAT40, Taper Shank, 1.25" Pilot MPN:C40-12SM4

Shell Mill Holder: CAT40, Taper Shank, 1.25in Pilot is an indispensable tool for machining operations requiring the utmost accuracy and precision across automotive manufacturing facilities; this holder delivers unmatched rigidity to secure endmills in place to prevent movement while under load reducing chatter marks which can lead to poor finishes on critical parts such as fuel injectors, valves or engine blocks by keeping tools square while traversing deep cavities demanding aggressive chip evacuation thus boosting productivity. Equipped with a pilot diameter of 1.25 inches and capable of taking collets up to a maximum diameter of 0.9438-inch opening; this holder also includes bearings on all axis, an adjustable locknut which helps to fine-tune for centering while dampening endmill whip thus maintaining the proper relationship with tool center height minimizing errors caused by shifts during spindle rotation making it a must-have component to produce high quality workpieces from start to finish whether in prototyping or volume production settings where precision is non-negotiable.
