KEUE CNC High Speed Steel Internal Hole External Cold Cutting Groove Tool Holder MGIVR/MGIVL MGMN Interchangeable Head
These MGIVR/MGIVL series internal grooving boring bars adopt an external coolant system with detachable modular heads, fully matching standard MGMN grooving inserts. Available in D16Q and D20R shanks with multiple head specifications, they are designed for precision internal grooving on CNC lathes.
The split-type head structure enables fast cutting head replacement without withdrawing the whole bar, significantly reducing machine setup downtime. The external coolant design delivers effective cooling and chip removal, ensuring stable cutting performance and consistent groove dimensional accuracy.
Widely applicable for grooving steel, stainless steel and engineering alloys, they cut down tooling inventory costs and offer reliable service life. They improve machining efficiency, lower overall production costs and support stable continuous production.
