CORE DRILLS — CARBIDE TIPPED

TAPER SHANK — FRACTIONAL SIZES

TYPE 2622 — TAPER SHANK — FRACTIONAL SIZES

Cutting diameter tolerance plus .000" minus .001".
Carbide tips brazed to one piece hardened tool steel bodies.
Large right spiral flute capacity permits higher feeds and speeds.
118ยบ included chamfer angle.

USE:

Core drills are designed for economically enlarging cored, punched or drilled holes, removing up to 30% of the hole diameter.
The balanced cutting action of the core drill removes considerably more material than a reamer, often eliminating the need for a final reaming or boring operation.
For cast iron, non-ferrous metals, some steels, composites, plastics and non-metals.
