Brazed Lathe Tool Bit: A brazed lathe tool bit is lathe tool in which the cutting point is a brazed tip permanently fixed to a tool bit. A tool bit is basically a cutting edge mounted on a shank (typically short in length) and held in its cutting position by a tool bit holder. Tool bits considered in the Brazed Lathe Tool Bit category typically have square or rectangular shanks.
Attribute Name Description of Attribute
Standards Code Brazed lathe tool bit designation used by the standards organization. Note that if the Brazed Lathe Tool Bit is used for boring operations (i.e., LATHE_TOOL_BODY.LATHE_TOOL_BODY_FUNCTION = BORING), the standards document specifies a different form of the Standards Code designation than for other lathe operations. Examples of this attribute are provided below. From ANSI B212.1-1984 (brazed lathe tool bits for boring), the 4 symbol designation is as follows: 1) letter indicating if the tool bit is solid (S) or tipped (T), 2) letter indicating if the tool bit is square (S) or round (R), 3) letter designation for the side cutting edge angle (A through H), dash, and 4) size designation for the tool bit square size in number of 1/16ths. Example: T S C - 8 Note: The value of item 1 will always equal T and the value of item 2 will always equal S for Brazed Lathe Tool Bits as defined in this table. From ANSI B212.1-1984 (general purpose brazed lathe tool bits), the 3 symbol designation is as follows: 1) letter designation for the tool shape (A through G), 2) letter indicating Right (R) or Left (L) hand for tool shapes A, B, F, G, and E with offset p oint (symbol not used for tool shapes C, D, and E with central nose angle), and 3) size designation for the tool bit shank in number of 1/16ths of width and height for square shanks or number of 1/8ths of width and number of 1/4ths of height for rectangul ar shanks. Examples: A L - 8 5 or E - 8
