Mitsubishi G2 Chipbreaker Uncoated Polished Carbide Milling Insert for High-Speed Aluminum Alloy Right Angle Shoulder Milling CNC cutting tools

The APGT1604PDFR-G2 HTi10 is uncoated ultra-fine grain carbide indexable shoulder milling insert originally from Mitsubishi, specially engineered for high-speed rough & finish side milling of non-ferrous metals and cast iron. Adopting right-hand PDFR geometry plus exclusive G2 chipbreaker structure and polished rake face, this insert drastically lowers cutting friction and effectively restrains built-up edge during high-feed aluminum machining, maintaining stable cutting performance in continuous and mild intermittent shoulder milling on BAP series right-angle face mills.

Mirror-finished insert surface optimizes chip curling and smooth chip evacuation, securing ultra-fine workpiece surface roughness and extended tool lifespan for non-ferrous batch precision machining.

• HTi10 ultra-fine grain uncoated tungsten carbide substrate features sharp cutting edge, outstanding anti-adhesion property, ideal for high-speed aluminum, copper and cast iron milling.
• Custom G2 inner chipbreaker groove controls chip curling perfectly to avoid long chip winding on workpiece and cutter body.
• Standard APGT1604 dimension, 11° clearance angle, precise mounting hole fully compatible with BAP400 series shoulder milling tool holders.
• Full polished front rake surface greatly reduces aluminum material adhesion, guarantees mirror finish after milling processing.
• Reinforced edge honing balances sharpness and chipping resistance, suitable for long-cycle continuous high-speed production.
