Milwaukee 48-20-8980 Glass Tile Drill Bit 1/8 Inch 5 Pack

Product Description

The Milwaukee Electric Tool Corp 48-20-8980 is a 1/8 inch glass and tile drill bit designed for clean, controlled penetration through hard, brittle surfaces. Constructed from high-speed steel, the bit maintains edge integrity when drilling through ceramic tile, porcelain, and glass substrates. This package includes 5 bits, making it a practical choice for jobs that demand consistent results across multiple holes. It is sized for use with standard drill chucks and is well suited to tasks where precision entry points are required without cracking or spalling the surrounding material.

This bit is used in residential and light commercial applications wherever glass or tile drilling is required. Common install scenarios include setting fixtures through backsplash tile, drilling glass panels for hardware mounting, and creating pilot holes in ceramic surfaces during bathroom or kitchen work. Tradespeople such as tile setters, plumbers, and electricians frequently use bits of this type when penetrating finished tile surfaces to run supply lines, mount fixtures, or route conduit. The 1/8 inch diameter makes it appropriate for small-diameter pilot work and precision applications.

Key Features

• High-speed steel construction for durability on glass and tile surfaces
• 1/8 inch diameter sized for precision pilot holes and small-diameter penetrations
• 5-piece pack provides multiple bits per purchase, reducing downtime on multi-hole jobs
• Compatible with standard drill chucks found on common corded and cordless drills
• Designed to minimize cracking and spalling on brittle tile and glass substrates

Compatibility

Designed as an OEM-style replacement-grade bit for use with standard 3-jaw drill chucks on corded or cordless drills rated for glass and tile drilling applications.

Installation Notes

Tile and glass drilling should be performed by qualified tradespeople following applicable safety practices. Always use appropriate eye protection and secure the workpiece before drilling. Apply light, steady pressure and use water or cutting fluid when possible to reduce heat buildup and extend bit life. Avoid high RPM starts on smooth glass surfaces to prevent bit walking.
