GL grooving and parting-off

The Pramet GL assortment for parting and grooving applications has been expanded with a range of high-pressure capable internal coolant tools. Additions include external tools GLAF and tools for sliding head machines GLAF-S, providing further options for highly productive machining. Always consider influence of coolant pressure (max. up to 140 Bar), generally speaking:​ the higher the pressure, the more increased tool life and improved chip-forming.

A new line of boring bars for internal grooving with GL inserts was released. The reinforced design of the blade ensures excellent stability during cutting and provides high precision even at high cutting speeds. The GL seating place is compatible with multiple insert styles, offering customers versatility and flexibility in their operations. The grooving diameter range starts from 32mm, making it suitable for a wide range of applications.

Dormer Pramet has expanded its range of Pramet GL grooving tools with three new families of tools for face grooving. The new tools include two axial types for right-hand or left-hand lathe rotation, and a radial 90° type for left-hand lathe rotation. All tools feature a reinforced blade and a robust design of the seating place, ensuring reliable security during demanding deep face grooving operations.

The range of Pramet GL inserts was expanded by single-sided long inserts GL.-S, designed for extra deep grooving and parting-off operations. Featuring a single cutting edge, these inserts are particularly useful in applications where surface quality on the face of the parted-off bar is critical. The absence of a secondary cutting edge prevents unintentional scratching of the surface while grooving deeper than 24 mm.
