Using your Alpha Dry Core Drill Bit is a breeze. First, make sure you've selected the right size bit for your project from the available options: 1/2', 3/4', 1', 1 - 1/4', 1 - 3/8', 1 - 1/2', or 2'. Then, attach the bit to a high - speed angle grinder with a 5/8' - 11 spindle. You're ready to start drilling on granite, engineered stone, porcelain, or crystallized glass countertops without water. Just apply steady pressure and let the bit do its job.
When using the drill bit, always wear safety goggles to protect your eyes from debris. Also, keep the drill at a reasonable speed, and don't force it too hard through the material, as this can damage the bit.
To maintain your drill bit, clean it after each use. You can use a brush to remove any dust or debris. Store it in a dry place to prevent rusting. With proper use and care, your Alpha Dry Core Drill Bit will serve you well for a long time.
