The Milwaukee Electric Tool Corp 48-20-8994 is a 3/8-inch drill bit engineered for cutting through tile and natural stone. Sold in a 5-pack, it is designed for tradespeople who regularly drill anchor and fixture holes in ceramic, porcelain, or natural stone surfaces. The bit is suited for work in bathrooms, kitchens, and commercial tile installations where clean, controlled penetration is critical. Each bit in the pack is sized at 3/8 inches, making it a standard choice for common anchor and fastener applications in hard-surface trade work.
This bit is used in residential and light commercial settings wherever tile and natural stone surfaces require drilling. Typical applications include plumbing rough-in anchor points behind tile walls, electrical fixture mounting through tiled surfaces, and general contractor tile-work requiring precise hole placement. The 5-pack quantity suits service professionals who need multiple bits on hand for high-volume or multi-site jobs.
Designed as an OEM-style replacement and standard consumable bit for use in rotary drills and hammer drills configured for tile and natural stone drilling applications.
Installation should be performed by a qualified tradesperson familiar with drilling into hard tile and stone surfaces. Always use water or appropriate cooling when drilling natural stone to prevent cracking and extend bit life. Power down any nearby electrical circuits before drilling into walls, and confirm no plumbing or conduit runs behind the work surface. Follow applicable building codes for anchor placement and fastener spacing.
