Eagle Cutting Tool VM4350-028-4-D Masonry Drill Bit

Product Description

The EAGLE CUTTING TOOL VM4350-028-4-D is a carbide-tipped masonry drill bit designed for boring through concrete, block, brick, and other masonry materials. The bit measures 7/16 inch in diameter with a 4-inch overall length, making it a practical choice for through-hole and anchor-setting work in standard-depth applications. Manufactured in the USA, this bit is built for repeated use in demanding field conditions. Licensed contractors, masons, and general tradespeople reach for carbide-tip bits like this when drilling into hard substrates where high-speed steel would wear prematurely.

This masonry bit suits residential and light commercial applications where anchors, fasteners, or conduit penetrations need to pass through concrete or masonry walls. Common install scenarios include setting anchor bolts, running electrical or plumbing sleeves through foundation walls, and securing framing to concrete slabs. The 7/16-inch diameter is a frequently specified size for wedge anchors and sleeve anchors used in structural and mechanical attachment work.

Installation Notes

Masonry drilling is typically performed by electricians, plumbers, masons, or general contractors depending on the application. Use a hammer drill setting when drilling into hard concrete or block for best performance and bit longevity. Always wear eye protection and a dust mask when drilling masonry, as silica dust is a respiratory hazard. Confirm anchor manufacturer specifications for the correct hole diameter and depth before drilling.
