60° Partial Profile Geometry and PVD VP15TF Grade

The IRG60-S 60° partial profile designation allows for the machining of metric (M), UNC/UNF, and BSP threads with varying pitches—within the range of 1.75 to 3.0 mm—simply by adjusting the final pass depth on the CNC machine. The VP15TF grade (featuring a PVD MIRACLE coating of AlTiN on a micro-grain cemented carbide substrate) offers an optimal balance between abrasion resistance and impact toughness, preventing chipping during interrupted cuts or aggressive entry into blind holes.

Technical Specifications

• ISO Application Range: Group P (structural, alloyed, and heat-treatable steels), Group M (austenitic/martensitic stainless steels), Group K (cast iron), and Group S (heat-resistant superalloys and titanium).

• Tool Holder Compatibility: Suitable for standard ISO internal threading boring bars designed for inserts with an inscribed circle (IC) size of 9.525 mm (3/8").

• Recommended Cutting Parameters (Guidelines):

  • Cutting Speed ??(V_c): 80 - 160 m/min (depending on the hardness of the steel and INOX).

  • Pass Strategy: Multiple passes penetrating altered or radial flank in 4 to 8 passes depending on the pass.

• Product Presentation: Original sealed box of 10 units.
