1 A smaller corner radius (r) will reduce the load on
“S” Sharp Corners
2 the workpiece and produce a smaller size burr • Cutting edge with positive rake and sharp corners
• When a minimum burr (pip) size is essential
2 At the same time, a large corner radius allows
for higher feeds and increased tool life • For small feeds
• For small diameters or thin walls
Feed • For CNCs, multi-spindle and screw machines
