                                    288 ISCAR DEEP HOLE DRILLINGDouble Tube SystemSingle Tube SystemThe high precision of the NPMX and TPMX inserts enables deep drilling with a diameter tolerance of IT10 and surface finish of 3 %u00b5m.The ISCAR-DEEP-DRILL family contains inserts with a variety of chipformer types. The chipformer type %u201cG%u201d is general and suitable for machining most materials. In order to improve performance, in some cases there are additional chipformer types, such as: %u201cB%u201d, %u201cBG%u201d, and %u201cDT%u201d. The %u201cB%u201d-type chipformer has the ability to improve chip control for heat-resistant alloy, titanium, stainless steel, Inconel, etc. The %u201cBG%u201d-type chipformer can improve chip control for difficult-to-cut steel, carbon steel, non-alloy steel, etc. The %u201cDT%u201d-type chipformer is designed to reduce machine load and is recommended for use on low power machines.The NPMX inserts are mounted on drilling heads with diameters up to 45 mm and are available with 2 types of chipformers %u201cG%u201dand %u201cB%u201d. The TPMX inserts are mounted on drilling heads with a diameter above 48 mm and are available with 4 types of chipformers %u201cG%u201d, %u201cB%u201d, %u201cBG%u201d, and %u201cDT%u201d. The tools with diameter ranges between 45 to 48 mm carry NPMX and TPMX inserts.GversatileBGchip control for difficult-to-cut steelBgood chip control for heat-resistant alloyDTto reduce machine loadThe ISCAR-DEEP-DRILL indexable inserts are available in several grade types, such as: IC920, IC5500, IC9025, IC508, IC908, IC520, and IC806.
