The Milwaukee Shockwave 3.5 in Impact Duty Phillips Bits are engineered to be the most durable, best fitting driver bits on the market. The Phillips bits feature Wear Guard Tip for increased wear resi more→stance which protects the fit over the life of the bit. The impact driver bits have and optimized Shockzone for each tip type and length of driver bit to absorb peak torque and prevent breaking. The Custom Alloy76 Steel is customized and heat treated per tip type to extend the life of the driver but by up to 50X vs. competitive impact driver bits. The Milwaukee Shockwave Impact Duty driver bits are built to deliver extreme durability for the most demanding applications.FeaturesSpecifications

The Milwaukee 4-pc tile and natural stone drill bit set to deliver up to 2x life in granite, stone, ceramic tile, and glass. Hammer mode capability provides faster drilling speeds when drilling natura more→l stone tiles, like granite and marble. Equipped with an aggressive 8-grind carbide head, these bits deliver up to 20% faster drilling. These bits feature reinforced tips that protect the carbide head. Milwaukee tile and natural stone drill bits can be used in drill-only mode or hammer drill mode and we don't recommend them for porcelain tile.

While most screw driving bits are simply compatible with impact drills and drivers, Irwin Impact Performance Series fastener drive bits are engineered for maximum durability and long life with impact more→drivers. These bits are forged rather than milled, so they fit fasteners more precisely, which reduces stripping and increases the life of the bit itself - Irwin's Impact Performance Series bits have three times longer life than traditional bits.
