R8 Collets, Collet Size (Inch): 1/2 , Material: Steel , Drawbar Thread Size: .437 x 20 RH , Tir: 0.001 , Overall Length: 4.10 MPN:17570039005000

The R8 collet is a versatile toolholder that is widely used for clamping round and hexagonal shanks of various tools and parts in machining operations. Made from steel material, the R8 collet offers high strength and durability. Its inch size of 1/2 makes it suitable for gripping medium-sized tools securely, while the 0.437 x 20 RH drawbar thread allows easy fastening to spindles with the corresponding taper pinch-to-pitch bored barrels in lathe or milling machines. Its TIR (Total Indicator Runout) of 0.001 means it maintains precise concentricity during operation, ensuring quality and consistency in machined parts. With its high accuracy and compatibility with various shank tool types, R8 collets are extensively used in industries such as automotive, aerospace, medical, dental, mold-making, and woodworking, among others for precise and efficient production processes.
