Milwaukee 48-20-8985 Glass Tile Drill Bit 1/2 in 5 Pack

Product Description

The Milwaukee 48-20-8985 is a 1/2 inch carbide-tipped glass and tile drill bit sold in a 5-pack. Engineered for controlled penetration through hard, brittle surfaces, it delivers clean entry holes without fracturing the surrounding material. The carbide tip geometry is designed specifically for non-rotary hammer use on glass, ceramic tile, porcelain, and similar hard substrates. Tile setters, glaziers, plumbers, and electricians reach for this bit when they need to core through finished surfaces cleanly and consistently. Weighing 0.44 pounds for the package, the set is compact enough for a tool bag or service van organizer.

This bit is suited for residential and light commercial applications where drilling through installed glass, ceramic tile, stone tile, or similar hard materials is required. Common install scenarios include running pipe or conduit penetrations through tiled walls, mounting fixtures on glass panels, and setting anchors through ceramic floor tile. The 5-pack quantity supports production work or ensures backups are on hand for high-wear drilling tasks.

Key Features

• Carbide construction for durability on glass, tile, and other hard surfaces
• 1/2 inch diameter for standard penetration and anchor hole sizing
• Designed to minimize chipping and cracking on brittle materials
• 5-pack quantity reduces downtime during production or service work
• Compact package weight of 0.44 pounds for easy transport

Compatibility

Designed for use with standard rotary drills operating at low speed without hammer action, suitable for drilling glass, ceramic tile, porcelain, and other hard non-rotary surfaces.

Installation Notes

This bit should be used with a standard rotary drill set to low speed with the hammer function disengaged. Applying steady, moderate pressure and using water or cutting fluid as a coolant will extend bit life and reduce the risk of cracking brittle materials. Mark the drill point with tape or a center punch dimple to prevent walking on smooth glass or glazed tile surfaces. Always wear appropriate eye protection when drilling hard materials.
