The Iscar A-PWLNL 16-3G is a new, left-hand indexable boring bar from Iscar's PWLN series, designed for internal turning and boring operations on CNC lathes and turning centers. Decoding the designation: "A" = cylindrical shank with coolant hole, "PWLN" = toolholder style accepting trigon (W-shape, 80° included angle) negative-rake inserts with no side rake and 0° clearance angle, "L" = left-hand cutting direction, "16" = 16 mm (approx. 5/8 in) shank diameter, "3" = insert size 3 (WNMG/WNMA 080 series), and "G" = coolant-through designation per Iscar convention. The body is manufactured from hardened alloy steel with an internal coolant channel that delivers high-pressure coolant directly to the cutting zone, enabling extended tool life and effective chip evacuation in deep-bore applications. The bar accepts WNMG 080408-style trigon inserts (W-shape, 80° point angle), and the third photo confirms the kit ships with an installed insert, spare insert, torx wrench, and Iscar SET HN 2.5 clamping hardware, all in Iscar's standard protective case (Iscar item 6596166, manufactured 10/03/2022, barcode 3606767).
