Positive turning inserts

ISO positive carbide inserts (PST) — six chip grooves for steel, stainless and cast iron finishing and general-purpose turning.

Galtona's PST range covers positive-geometry turning across finishing, general-purpose, and heavier engagement, with six dedicated chip grooves, each FEM-optimised for its application.

For steel finishing: PWX (Masterfinish geometry, high surface quality, also available as a heavy-turning grade) and JF (cermet TCM10 finishing).

For chip control and general-purpose turning: WSF+ (optimised chip control across steel and stainless grades) and WM+ — the broadest range, spanning 7 insert shapes across GTCP115, GTCP125, GTCP125HP, GTCP135 steel grades plus stainless GTCM120HP/GTPM125/GTPM135M and cast-iron GTCK120.

For stainless, cast iron, non-ferrous, and exotic materials: EN-EF (sharp ground edge, extreme finishing) and LMF+ (new chipbreaker, available in a fine finishing grade and a heavier uncoated H216T grade for larger depths of cut).

WM+ — general-purpose turning

WM+ — General-Purpose Turning

The widest range in the family — 7 insert shapes across steel, stainless, and cast-iron grades.

Example: CCMT 09T308-WM+. Depth of cut 0.50–3.00 mm, feed 0.21–0.12 mm (steel/stainless); cast iron "K20" extends to 1.00–3.00 mm / 0.41–0.22 mm.
