Get Connected!

Having the right spindle connection on your machine at the start of a heavy-duty job is as important as planting your feet firmly before a heavy lift. It gives you stability, balance, and extra strength to do the job.

Kennametal’s spindle interface tooling can give you that firmly planted stability you need in heavy-duty applications.

KM4X in CAD Program

KM4X™ Breakthrough Technology

New KM4X™ is the spindle connection you want for aggressive machining of large, structural components like titanium aerospace parts. It features 3-surface ring contact for extra stability in rotating and stationary operation. KM4X™ has 3x the bending power so you can push your cutting tools to the limit and push out more production.

But we didn’t stop there. Use KM4X™ on both new and old machining centers. The universal design easily accepts both old-style and new-style tools. It has higher metal removal rates and is balanced-by-design to run at higher spindle speeds.



KM™ Quick-Change Tooling (ISO-Standard Interface)

Our KM™ tooling has long been an industry favorite for solid, dependable spindle connections. Now it’s an ISO standard (ISO 26622), as recognized by the International Organization for Standardization.

KM quick-change has a secure 3-point contact, and can be used on multi-tasking, turning, rotating, and transfer machines in manual, semiautomatic, or fully automatic mode. KM can take advantage of a machine’s fully automatic capabilities, like tool storage, and tool-handling, and signal-activated locking mechanisms, to dramatically improve machine 

HSK Tool Holder

HSK Units

Our HSK units are widely used for high-speed machining. These balanced-by-design tools are well suited for machining centers and milling machines with automatic tool changers.


Steep Taper Adapter

Steep Taper Tooling

Our BT, CV, and DV steep taper tooling is balanced-by-design and features 1-point contact. Through-coolant is a standard feature when permitted by the toolholder design.
