MGIVR/MGIVL A- MGMN Split Slot Cutter Boring Tools Product Category
These MGIVR/MGIVL series internal grooving boring bars adopt a modular detachable head design with through-tool internal coolant, fully compatible with standard MGMN grooving inserts. Available in D16Q and D20R shank specifications, they are purpose-built for precision internal grooving on CNC lathes.
The internal coolant system delivers cutting fluid directly to the cutting edge, effectively enhancing chip evacuation and reducing cutting heat buildup. The split-type head structure enables fast head replacement without withdrawing the whole bar, greatly cutting down machine setup downtime.
Widely applicable for grooving steel, stainless steel and engineering alloys, they ensure stable cutting performance and consistent groove dimensional accuracy. They lower tooling inventory costs, extend service life and effectively boost overall internal grooving productivity.
