Drill through brick, block, tile, metal, wood, and plastic without switching bits. This Irwin Multi-Material jobber-length bit uses a brazed carbide tip with a diamond-ground four-facet point that starts clean and resists walking. The double-milled flute clears debris fast and the duo-tone surface finish reduces friction for longer bit life and better battery performance in cordless drills.

• Brazed carbide tip with diamond-ground four-facet design - clean centered starts, no walking
• Drills masonry, metal, wood, tile, glass block, and plastic with one bit
• Double-milled flute clears dust and chips fast for sustained drilling speed
• Engineered for rotary drilling - tough enough for hammer drill use in masonry
• Duo-tone surface finish reduces friction and heat for longer bit and battery life
• Jobber length straight shank fits 3/8" and 1/2" drill chucks - keyed or keyless

1/8" diameter, 3" overall length jobber bit. Small-diameter holes for light-duty fasteners - pilot holes for #6/#8 wood or sheet-metal screws, drainage holes in tile/ceramic, and small passes through plastic or thin metal panels. The 1/8" bit also reaches into restricted spots where a chuck on a larger bit would not clear.

Tip: Switch the drill to rotary mode (hammer off) when going through metal, tile, glass block, or thin plastic to avoid cracking or chipping the workpiece. Use hammer mode only when the carbide tip is fully into solid masonry. Withdraw the bit periodically to clear dust from the flute - clogged flutes overheat the carbide and shorten bit life.
