Kennametal 3.37100R720 is an indexable chamfer and countersink combination drill designed to create both chamfer and countersink features in a single pass for 8–10 mm holes. It uses replaceable inserts (indexable) to maintain edge geometry and extend tool life between insert changes. This precision tool streamlines hole preparation by delivering accurate chamfer and countersink in the 8–10 mm size range, consolidating two operations into one step.
