High-Stability MCKNR Lathe Tool Holder for Heavy Roughing
The MCKNR tool holder is specifically engineered for external turning where high material removal rates and tool rigidity are the top priorities. As a premier lathe turning tool holder (110 searches/mo), the MCKNR series is the “heavy-duty sibling” in the CNMG holder family.
75° Approach Angle for Superior Strength
The standout feature of the MCKNR tool holder is its 75-degree approach angle. Unlike 91° or 95° holders, this geometry:
-
Distributes Cutting Forces: Spreads the load over a larger portion of the carbide edge.
-
Protects the Insert: Ideal for heavy-duty roughing and interrupted cuts.
-
Enhances Heat Dissipation: Allows for faster feed rates without compromising the CNMG tool holder setup.
M-Type Double Clamping (Multi-Lock)
Safety and precision are guaranteed by the M-type clamping system. This system uses a top clamp and a center pin to lock the lathe insert holder securely. It prevents any rotation or lifting of the insert, which is crucial when performing the high-torque operations that the MCKNR is designed for.

Q: When should I use MCKNR instead of PCLNR?
-
A: Use the MCKNR when you need extra tool strength for heavy roughing or when dealing with scaly surfaces. The 75° angle is much stronger than the 95° angle of a PCLNR, although it cannot be used for 90-degree shoulders.
