Milwaukee 48-20-8991 Tile Stone Drill Bit 3/16 in 5-pack

Product Description

The Milwaukee Electric Tool Corp 48-20-8991 is a 3/16-inch drill bit engineered for cutting through tile and natural stone. Sold in a 5-pack, it is designed to deliver clean, accurate holes in hard, brittle materials where standard twist bits fail. This type of bit is a standard tool on tile and stone installation jobs, renovation work, and surface-mount mechanical tasks where anchors or fasteners must penetrate ceramic, porcelain, or natural stone substrates. Electricians, plumbers, and general contractors reach for bits like this when routing through tiled walls or floors during rough-in or finish work.

The 48-20-8991 is suited for residential and light commercial applications involving ceramic tile, porcelain tile, and natural stone surfaces. Common use cases include setting wall anchors in tiled bathrooms and kitchens, drilling pass-throughs in stone countertops, and creating penetrations for plumbing or electrical rough-in behind tiled surfaces. The 5-piece pack supports multi-hole jobs and provides backups for a consumable that sees wear on abrasive materials.

Key Features

• 3/16-inch diameter sized for standard anchor and fastener penetrations in tile and stone
• 5-pack quantity supports high-hole-count jobs and provides replacement bits for a wear-prone consumable
• Designed specifically for tile and natural stone — not a general-purpose twist bit
• Compact, lightweight form factor at 0.11 pounds per pack

Compatibility

Designed as a specialty replacement and consumable drill bit for use in tile and natural stone applications. No specific tool or system compatibility data was provided in the product information.

Installation Notes

Tile and stone bits are typically used by tile installers, plumbers, and electricians during finish or renovation work. Use low drill speed and steady pressure to avoid cracking brittle tile or stone; never use hammer or rotary-hammer mode on tile. Keep the bit cool during extended drilling — water or a cooling lubricant helps prevent overheating and cracking. Follow all applicable local codes when creating penetrations through finished surfaces for mechanical, electrical, or plumbing purposes.
