Tungaloy Introduces Coolant-Through Holders for Small Bore Internal Grooving


Iwaki, March 2020 — Tungaloy’s SNG series of indexable internal grooving tools now includes coolant-through holders.

The new SNG holders are designed for the internal grooving of bores with diameters as small as 8.0 mm (.315″) up to 24.0 mm (.945″), while promising reliable chip evacuation.

The shanks are made of either steel for economy or tungsten carbide for long reach areas where tool steadiness is vital.

Combined with the popular GMR style chipbreaker, the SNG coolant-through holders virtually eliminate chip nests, reducing part scraps and machine downtimes, while improving machining efficiency.
