Irwin Multi-Material Jobber Length Bits 5/16" X 4-3/4"
Multi-Material Jobber Length Bits Features:
IRWIN Multi-Material drill bits drill through just about any type of material out there – brick, block, tile, metal, wood, plastic and marble – they’ll even drill through multiple materials at the same time. These versatile bits are designed specifically for rotary drilling, but are tough enough to be used with hammer drills.
Carbide tip has a unique diamond-ground, four-facet design with sharper cutting edges for centered starts with no walking, fast drilling, and excellent hole quality in a variety of materials.
Double-milled flute ensures fast, efficient removal of drilling dust and debris to increase speed and prevent clogging.
Compatible with all standard 1/2" and 3/8" chuck drills.
