NOTE: Indexable drill bodies require BOTH periphery and center inserts. The styles are NOT interchangeable. 
Remember to order both periphery and center inserts.
I
ndexable drills feature a tool steel body, and typically two inserts: 
a CENTER INSERT that cuts the center of the hole, and a PERIPHERY INSERT 
that cuts the outside hole diameter. Inserts are usually secured to the tool 
body using screws, and when the cutting edge becomes dull, the insert is indexed 
to expose a new cutting edge.
