Lh Dottie MD6 Masonry Drill Bit 1/2 Inch Carbide

Product Description

The LH DOTTIE MD6 is a tungsten carbide tipped masonry drill bit designed for percussion and rotary drilling applications. With a 1/2 inch drill diameter and a 4 inch overall length, this bit delivers reliable penetration through hard masonry surfaces. The slow spiral, 3-flute geometry helps clear debris from the bore while maintaining cutting speed. A black oxide coated finish adds surface hardness and mild corrosion resistance. The tempered steel body is built to handle the repeated impact loads of hammer drill operation without premature wear. Licensed electricians, plumbers, and general construction tradespeople reach for this bit when anchoring in masonry substrates.

The MD6 is suited for drilling into brick, concrete, tile, slate, and cinder block in both residential and light commercial settings. Typical uses include setting anchor bolts, running conduit penetrations, and mounting brackets or junction boxes to masonry walls. The straight 1/4 inch shank fits standard keyed and keyless drill chucks commonly found on corded hammer drills and rotary drills. It is sold individually in a display pouch, making it practical for single-job use or replenishment of a tool kit.

Installation Notes

Installation is typically performed by electricians, plumbers, or mechanical contractors drilling anchor or penetration holes in masonry. Power down or unplug the drill before changing bits. When drilling into concrete or block walls, confirm no embedded conduit, rebar, or utilities are present in the drilling path before starting. Use appropriate eye protection and dust control measures when drilling masonry, in accordance with applicable jobsite safety requirements.
