JB/T 7966.5-1999 Die milling cutters Part 5: Flattened straight shank conical end mills

JB/T 7966.5-1999 This standard is a revision of JB/T 7966.5-95 "Mold milling cutter flat type straight shank conical end mill". During the revision, only editorial changes were made according to relevant regulations, and the technical content was not changed. The original standard is not equivalent to the international standard ISO 3940-1977 "Straight shank conical die milling cutter" type II. This standard is part of the JB/T 7966 "Mold Milling Cutter" series of standards, which includes the following 10 parts: JB/T 7966.1: Straight shank cylindrical ball nose end mill JB/T 7966.2: Flattened straight shank cylindrical ball nose end mill JB/T 7966.3: Morse taper shank cylindrical ball nose end mill JB/T 7966.4: Straight shank conical end mill JB/T 7966.5: Flattened straight shank conical end mill JB/T 7966.6: Straight shank conical ball nose end mill JB/T 7966.7: Flattened straight shank conical ball nose end mill JB/T 7966.8: Morse taper shank conical end mill JB/T 7966.9: Morse taper shank conical ball nose end mill JB/T 7966.10: Technical conditions This standard specifies the type and size of flattened straight shank conical die milling cutters. This standard applies to flattened straight shank conical die milling cutters with a diameter of 6~12mm. This standard was first issued in 1986 as GB 6336.5-86 and was adjusted to JB/T 7966.5-95 in April 1996.
