Irwin 3/16" Glass & Tile Carbide Drill Bit

This IRWIN® 3/16-Inch Glass and Tile Carbide Drill Bit gives you enough strength to drill through the roughest materials. It's made for glass and tile, so you can work through them with minimal resistance. This Irwin glass and tile drill bit features a tungsten carbide tip with enough hardness to transform your drill into a multi-function tool. It measures 4 inches and it works with a minimum chuck size of 0.25 inches. The carbide tile drill bit features a special flute near the center that drives dust away from your contact surface while it spins; this keeps your area clear and allows for much faster drilling. A spear point at the head drives the drill bit downward as it pushes dust back up through the hole.
