TPMX deep hole drilling insert is with high-performance and designed for deep hole drilling, internal boring, counterboring, and trepanning operations. The TPMX insert is primarily used as the cutting element in deep hole drilling systems, directly engaging in the cutting process to remove material and form the bore, working together with guide pads for balanced and stable drilling. It is typically used in combination with deep hole drilling tool bodies and shanks (such as BTA drilling systems, gun drill shanks, and indexable deep hole drill heads) to achieve high material removal rates, excellent hole straightness and surface finish, especially crucial for deep holes with high length-to-diameter ratios or precision boring applications. It is suitable for aerospace components (landing gear, engine shafts), oil & gas and energy parts, mold and die manufacturing (ejector pin holes, cooling channels), automotive components (crankshaft oil holes, injector bores), hydraulic cylinders, and medical device manufacturing.
