If you want one drill bit kit that can handle a variety of household materials, the OSTTE Masonry Drill Bit Set is built to cover common DIY jobs—from hanging hardware in concrete or brick to careful entry holes in tile or glass.

Each bit uses a precision eccentric tip with a 4-blade serrated head to help self-center and reduce “skating” on slick surfaces like glazed tile and marble. The tips are made from YG6T carbide alloy for hardness and heat resistance, and the 1/4″ hex shank is designed for quick, secure changes in many drills and impact drivers.

The set includes 12 pieces spanning eight sizes (1/8″ through 9/16″) and comes with a storage case to keep everything organized. For harder stone, using water for cooling can help extend bit life.
