Grooving and parting tools with carbide inserts
Carbide grooving inserts with matching holders, boring bars and blades — parting and grooving tools from the UK.
Galtona's Grooving range (Grooving Metric Catalogue) covers insert systems and toolholders for parting, grooving, and turning operations: double-sided (GD), single-sided (GO and GS), and axial (GA) inserts across 7 chip-breaker geometries (M1, F1, ST1, T, M, MM, LM) for steel, stainless, cast iron, exotic alloys, and non-ferrous metals.
Toolholders span monoblock external holders (standard and reinforced, with optional internal coolant), boring bars for internal grooving, the modular Module GA / Module Holder axial-grooving system, and hardened parting blades (GBN/GBR/GBL) with matched clamping blocks.
As with the rest of Galtona's tooling program, custom blanks, semi-finished, and finished products can be developed in collaboration with customers where standard catalogue tools don't fit specific requirements.

Spare parts: Clamping screw M6.0×25 (MM22485, no-cooling block), grub screw M6.0×8 (MM11960993) and clamping screw M6.0×12 (MM11776816, cooled block).
How to use the system: (1) insert the mounting key with the handle towards the front into the 2 tool location points; (2) move the key in the direction of the arrows to open the insert seat; (3) position the insert pressing it against the location face; (4) move the key forward to lock the seat and clamp the insert securely. Always maintain tension on the key while changing inserts.
