Milwaukee 48-20-8988 Glass Tile Drill Bit Set 4 Piece

Product Description

The Milwaukee Electric Tool Corp 48-20-8988 is a four-piece glass and tile drill bit set designed for clean, controlled drilling through ceramic tile, porcelain, glass, and similar hard, brittle surfaces. Each bit is constructed from high-speed steel with a carbide tip that initiates cuts without cracking or chipping fragile materials. The set covers four common diameters: 1/4 inch, 3/8 inch, 1/2 inch, and 3/4 inch. This range handles most standard tile work, fixture cutouts, and glass drilling tasks encountered in residential and light commercial settings. Electricians, plumbers, tile setters, and general contractors keep a set like this on hand for penetrations through backsplashes, shower surrounds, and glass panels.

This bit set is suited for residential and light commercial tile and glass drilling applications. Typical uses include drilling anchor holes through wall tile for fixture mounting, cutting access points through glass panels, and boring openings in porcelain or ceramic tile for plumbing and electrical rough-in work. The four included sizes address the majority of standard fastener and fitting diameters encountered in everyday trade work. The set is sold as a single unit of measure per package.

Installation Notes

Carbide-tipped glass and tile bits should be used at low to medium drill speeds without hammer mode engaged, as percussive action will crack tile and glass. A licensed tile setter, plumber, or electrician typically installs hardware requiring tile penetration. Use water or a small amount of cutting fluid at the drilling point to reduce heat buildup and extend bit life. Always wear eye protection when drilling glass or ceramic tile due to the risk of chipping and fragment ejection.
