Minerallac 61109 Masonry Drill Bit 3/16 X 3-1/2 Inch

Product Description

The MINERALLAC 61109 is a masonry drill bit sized at 3/16 inches in diameter and 3-1/2 inches in overall length. Designed for drilling into concrete, brick, block, and other masonry substrates, this bit is a standard tool for tradespeople securing conduit hangers, anchors, pipe straps, and electrical or mechanical hardware to masonry surfaces. At 0.1 pounds, it is a lightweight, single-bit addition to a service kit. Electricians, plumbers, HVAC technicians, and general contractors routinely use masonry bits of this size when setting fasteners in residential and light commercial construction.

This bit is suited for use in rotary hammer drills or standard hammer drills when drilling pilot holes for anchors and fasteners in concrete block, poured concrete, or brick walls. The 3/16-inch diameter is a common size for small sleeve anchors, screw anchors, and similar masonry fasteners used to mount lightweight mechanical and electrical equipment. It fits standard drill chucks and is appropriate for both new construction rough-in work and retrofit service calls where masonry penetrations or anchor points are needed.

Installation Notes

Masonry drilling should be performed by qualified tradespeople following applicable codes such as the NEC or IPC where fastener placement relates to code-regulated installations. Always wear eye protection when drilling masonry. Ensure the drill is set to hammer mode for masonry substrates, and confirm anchor manufacturer specifications for required hole diameter and depth before drilling.
