Iscar CA2.91>3.15-EX-12/14 7006859 Dr. Twist Indexable Drill Cartridge

This is a new Iscar CA2.91>3.15-EX-12/14 indexable drill cartridge (Iscar item # 7006859 / K7564255) for the Dr. Twist modular drilling system, designed as the outer (peripheral) cartridge for drill bodies in the 74–80 mm diameter range. The part number decodes as follows: "CA" denotes a cartridge for the Dr. Twist system; "2.91>3.15" specifies the insert pocket size range in inches (accepting inserts from 2.91 to 3.15 in, i.e. the outer seat); "EX" designates the external/peripheral seat position within the drill body; and "12/14" indicates compatibility with 12- and 14-tooth (flute) Dr. Twist drill bodies. The cartridge body is machined from hardened tool steel with a nickel-finish, features a precision-ground spherical insert seating pocket and a slotted clamping foot secured by two Torx-head clamping screws (included), and is manufactured in Korea to Iscar's tight dimensional tolerances for repeatable insert indexing on large-diameter Dr. Twist indexable drills used in deep-hole and large-diameter drilling of steel, cast iron, and stainless steel workpieces.
