External toolholders and internal boring bars
Compare Kennametal and WIDIA turning holders by exact catalog designation, shank dimensions, cutting hand and matched insert references. External holders and internal boring bars have different setup constraints; select the correct tool for the operation.
Check machine fit and working dimensions
Review shank height or diameter, width, overall length and the working dimensions shown for the exact configuration. For boring bars, confirm the manufacturer’s bore limits where supplied. Published inch values do not make an inch holder a metric substitute.
Build the complete assembly
Use the exact insert and replacement-component links to select a compatible assembly. Check insert seat and clamping arrangement, then match screws, clamps, seats and keys by article number. Family similarity alone is insufficient.
Use technical references for the selected configuration
Compare the selected material-number row with its relevant manufacturer document. Family drawings show dimensional references; they do not replace the exact configuration’s specifications.
Frequently asked questions
Can I request an insert, holder and replacement parts together?
Yes. Choose each exact configuration and quantity, add the components to Quote, and send one request to Tech Tool.
What information helps identify a replacement?
Include the full catalog designation, material number and quantity. Add the existing holder or insert article and workpiece material when you need selection assistance.
