Masonry Drill Bit · 3/16 in x 6 in - For Concrete and Brick - MDB3166

What this product is for

This masonry drill bit is used to drill small-diameter holes in concrete, brick, block, and similar masonry materials. The 3/16 in diameter is commonly selected for anchor and fastening work where a clean, accurate hole is required.

Use for

Use for drilling into concrete, brick, masonry block, plaster, tile, and other similar materials where a masonry bit is appropriate. Typical jobs include anchor installation, mounting electrical boxes or clips, and running small fasteners into masonry.

Avoid for

Do not use this bit as a general-purpose wood or metal bit. Avoid applications that require an SDS-Plus shank unless your tool matches the bit shank. For reinforced concrete, hard aggregate, or production drilling, confirm the exact tip style and shank type before ordering.

Best for

Best for electricians, contractors, and maintenance crews who need a common small masonry bit size for anchors, clips, and light mounting work in concrete or brick.

Installed in

Used in residential, commercial, and institutional construction and service work. Commonly carried for site drilling in walls, slabs, block, and brick surfaces.

Why this product exists

This size fills a common need for small anchor and fastening holes in masonry. A 6 in overall length gives added reach compared with shorter bits while still fitting many standard drill and hammer drill tasks.

Compared with similar products

Compared with shorter masonry bits, a 6 in bit can help reach past finishes or into deeper mounting points. Compared with SDS-Plus rotary hammer bits, straight-shank masonry bits are typically chosen for standard drill chucks, but the exact shank style for MDB3166 could not be verified from reliable source material and should be confirmed before purchase.
