Tool Selection Guide Choosing the Correct Small Hole Boring Bar 2 Determine boring bar (D). A Select shank size (D) based on your machine’s requirements. 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.CAB (See recommended maximum overhang chart on page D86.) For indexable tooling, go to step 3. For all other tooling systems, go directly to step 4. C Determine lead angle (KRA). Zero degree lead angle is used when maximum stability is required. Lead angle may vary based on changing conditions, such as boring in a blind hole. 3 Determine which chipbreaker is best for the material to be machined. Consult the Small Hole Boring Chipbreaker Geometry charts on pages D34–D37. 4 Determine which grade is best for the material to be machined. Consult the Grades and Grade Descriptions charts on pages D38–D39. D6 widia.com
