142 ISCAR GENERAL PURPOSE DRILLINGThe SCD%u2026AH5 are solid carbide drills for hard materials with a hardness of 50-70HRc. These drills are available with a diameter range of 3 to 10.5 mm equivalent to 0.118 to 0.413 inches with tolerance m7 in length to diameter ratio of 5XD without internal coolant holes. The very rigid design with a thick reinforced web and low helix angle, prevents breakage which may be caused by micro-chipping. A special edge preparation provides a smooth cut and narrow optimized flute for machining hard materials and provides uninterrupted flow of typical small chips. The SCD%u2026AH5 are made from IC903, which is comprised of IC03 ultra fine substrate and the latest TiAlN PVD coating. They feature excellent performance, superior hole quality, reliability and in addition provide an economical solution. SCD%u2026AH5 are used in die and mold, aviation and aerospace, automotive, power train, power generation, oil and gas, and medical industries.The SCDT %u2026-M%u2026 are solid carbide step drills with internal coolant holes in the diameter range of 2.5-8.5 mm, which are compatible with ISO M thread standard of M3 to M10 pre-thread hole dimensions and expand the existing DCT... CHAM-DRILL Pre-Thread line. The dimensions of the solid carbide pre-thread drills are according to DIN 6537 and the step length are according to DIN 8378. The outer cutting drill diameter manufacture according to m7 tolerance and round shank according to h6 tolerance. The drill point angle is 140%u00b0 and spiral helix flute is 30%u00b0. The straight cutting edge and pinpointed chisel geometry is designed for machining ISO P, ISO M, ISO K materials. Submicron IC08 substrate with 10% cobalt content and the latest IC900 TiAlN PVD coated grade increase wear resistance and enable high cutting conditions. These step drills are suitable for machining any blind or through hole applications requiring a top chamfer, thus providing an applicative and cost-effective machining solution.
