BS ISO 514:2014 pdf free.Turning tools with carbide tips一Internal tools
This International Standard specifies the types and dimensions of turning tools with carbide tips; it deals only with internal tools.
The shank sections and the inserts used are selected respectively from those defined in ISO 241 and ISO 242.
NOTE External tools and the definition of right-hand and left-hand tools are the subject ofISO 243; designation and marking are the subject of ISO 504.
The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

ISO 242, Carbide tips for brazing on turning tools
Only two types of internal tools, considered to be those most generally used, are provided for; they are tool No.8 and tool No.9, which differ from each other only in the shape of the end of the operative portion.
Both types may be made either with a square shank or with a cylindrical shank, the front portion of the tool being of round section in both cases.
Dimension I shown in Table 1 is the nominal length of the carbide tip, type A or C, selected from those specified in ISO 242; this dimension is equal to approximately 0,6 d.
Only one range of overall lengths is specified, the length being a function of the diameter d.The lengths are scaled approximately in the series of preferred numbers R 40/3 and are a practically linear expression in terms of d, no value departing by more than 15 mm from the value obtained with the formula:10d+50mm
To permit the production of holes as small as possible, a bend of 15° is specified for the operative portion,with a dimension n virtually equal to 0,4 d and a cutting edge located at a distance equal to 0,2 d below the upper plane of the shank of the tool.BS ISO 514 pdf free download.
