Tool Selection Guide Choosing the Correct Small Hole Boring Bar Determine Materials to Be Machined and the Appropriate Insert B Determine bore depth (how far the boring bar extends from the holder). Multiply bar diameter by 4. If bore depth is less, use a steel bar. If bore depth exceeds 4:1 ratio, use a carbide bar. Use L1 or L4 depending on bar selected. (See recommended maximum overhang chart on page C160.) For indexable tooling, go to step 3. For all other tooling systems, go directly to step 4.
