11 A smaller corner radius (r) will reduce the load on “S” Sharp Corners
| the workpiece and produce a smaller size burr | • Cutting edge with positive rake and sharp corners | |
| 22 At the same time, a large corner radius allows | • When a minimum burr (pip) size is essential | |
| for higher feeds and increased tool life | • For small feeds |
