Indexable Drill Bit Inserts
Indexable drill bit inserts install onto the tip of compatible indexable drill bits to form a cutting edge for creating holes in workpieces. The inserts mount into seats that are sized and shaped for specific insert types. They can be rotated (indexed) to expose a fresh cutting edge when the old one dulls. They can be replaced with new inserts of the same type or different types without removing the drill bits from the machine. Drill bits with indexable inserts require fewer tool changes than solid tools in high-volume metalworking and fabrication applications with high speeds, high feeds, and difficult-to-machine materials.
