278 ISCAR DEEP HOLE DRILLINGFINE-BEAM Indexable InsertsThe ISCAR FINE-BEAM line provides solutions with indexable inserts for deep drilling methods, such as Single and Double tube system. The ISCAR FINE-BEAMline is based on peripheral indexable inserts NPHT with 2 cutting edges as well as internal and central indexable inserts NPMT with 2 cutting edges.The main features of this indexable solution are cost-effectiveness and functionality.All advantages of indexable solution are known and proven themselves over timeThe high precision of the NPHT insert enables deep drilling with a diameter tolerance of IT10.The NPMT insert exists in two forms: NPMT %u2026L and NPMT %u2026R. The NPMT %u2026L is a central insert designed to penetrate the material. The NPMT %u2026R is an intermediate insert designed for overlapping between the central and peripheral insert.All inserts belonging to the ISCARFINE-BEAM line are available with 2 types of chipformers - %u201cG%u201d and %u201cHF%u201d. The %u201cHF%u201dchipbreaker helps to stabilize the drilling process while using high feed, especially in difficult to machine materials such as ISO-M (Stainless steel and cast steel), ISO-S (High temp. alloys and Titanium alloys), and ISO-H (Hardened steel) materials. Selection of the GF or DT chipformer depends on the feed rate (mm/rev) according to the cutting conditions in the recommended table.Chipbreaker Comparison HF - provides drilling stability at high feed rateschipbreaker cross-sectionG chipbreakerHF chipbreakerNote for mounting a drill head:Please be sure to use a wrench for a drill head to be clamped firmly.The FINE-BEAM line inserts are available in several grade types, such as: IC908, IC520, and IC806. Selection of an insert grade is recommended to perform according to the table beloNPHTIC908 IC520 IC806P H H H I I IM I I I H H HK H H H I IN H H H I IS I I I H H HH I I H H H
