Minerallac Tapcon Carbide-Tipped Masonry Drill Bit

Minerallac Tapcon Carbide-Tipped Masonry Drill Bit

The Minerallac Tapcon Carbide-Tipped Masonry Drill Bit is a 5/32" x 3-1/2" drill bit engineered for pre-drilling anchor holes in concrete, brick, block, and other masonry substrates. Its carbide-tipped point is designed to stand up to the abrasive nature of masonry materials, holding an edge through repeated use where standard twist bits would quickly dull or fail. The 5/32" diameter is sized to match Tapcon-style concrete screw anchors, helping installers create a properly sized pilot hole for a secure, snug anchor fit. At 3-1/2" in overall length, the bit provides enough working depth for typical electrical box, bracket, strap, and equipment mounting jobs on masonry walls and floors. Electricians, low-voltage installers, and general contractors rely on properly sized carbide-tipped bits like this one to speed up masonry anchor installation while reducing bit wear and rework.

Key Features

• Trade Size: 5/32" diameter x 3-1/2" overall length, sized for standard Tapcon-style anchor installations.
• Carbide-Tipped Point: A carbide cutting tip resists wear and heat buildup, holding a sharp edge longer than standard steel twist bits when drilling into concrete, brick, and block.
• Tapcon-Compatible Sizing: Diameter matched to Tapcon-style concrete screw anchors, helping ensure a properly sized pilot hole and secure anchor engagement.
• 3-1/2" Working Length: Provides sufficient depth for drilling through typical masonry thicknesses encountered in electrical box, strap, and bracket mounting.
• Masonry-Specific Design: Engineered for drilling into hard, abrasive substrates such as concrete, brick, and block rather than wood or metal.
• Consistent Pilot Holes: Helps produce a clean, consistently sized hole that supports proper anchor seating and holding strength.
• Reduced Bit Wear: Carbide construction helps the bit maintain performance over repeated masonry drilling applications, reducing the need for frequent bit changes.
