Annular Cutters

Delta supplies DrillCo annular cutters for that quick, clean, finished hole.

Broach cutting using DrillCo cutters means you can produce large diameter holes
efficiently and quickly with lessenergy, faster penetration and less thrust. Rather
than drilling out the metal with a solid drill, DrillCo cutters removesonly the periphery
of the hole, ejecting a slug at the end of the cut. Tests show that a solid drill will
take 3 minutes, 45 seconds to drill a 1-1/4" hole in 3/4" plate. A DrillCo cutter can
do the same job in 35 seconds.
