 Large Diameter Drilling ISCAR is introducing the CHAM IQDRILL drill family for the drilling range of 33 to 40 mm with 3 and 5 length to diameter ratios. The CHAM IQDRILL features a unique design, utilizing the carbide flexibility for self-locking; eliminating the need for clamping accessories. The robust structure of the drill with the concave cutting edge design enables drilling at high feed rate, providing very accurate IT8 – IT9 hole tolerance. The new design features a shorter overall drill length, compared with other drills with the same length to diameter ratios, which provides higher tool stiffness and stability. The drill flutes have twisted coolant nozzles and carry indexable spade type drilling heads. The currently available drilling heads are for use on carbon and alloy steel (ISO P). They are made of IC908, a PVD coated grade. |
