Minerallac 59986 – Frequently Asked Questions

1) Will this Relton bit fit my SDS rotary hammer, or do I need an SDS-Plus chuck?
The bit uses an SDS-style shank that drops into an SDS rotary/hammer drill chuck for quick change with positive, slip-resistant engagement. It is not a round-shank bit for a standard keyed or keyless drill chuck. If your tool takes SDS-Max or spline shanks, this is not the bit for it.
2) Can I use this carbide bit to drill through structural steel or tile instead of concrete?
No. This is a carbide-tipped masonry bit intended for concrete, concrete block, and masonry substrates under rotary/hammer action. Steel needs a twist drill in a rotating-only tool, and hammering a masonry bit into tile or glazed surfaces will chip the face. Use it for anchor holes and through-wall holes in masonry.
3) Is a 6 inch bit long enough for a through-wall hole in a block wall?
The 6 inch overall length includes the shank, so usable drilling depth is shorter than 6 inches. It is sized for anchor holes and deeper anchor or through-wall work per the product data, which covers typical single-wythe block and standard-depth anchor sets. For deep through-penetrations in thick poured concrete, step up to a longer bit.
4) What jobs do electricians actually use this Relton masonry bit for?
Typical uses called out are anchor hole drilling in concrete and masonry, conduit strap and support mounting, and anchoring electrical boxes and fixtures to masonry walls, on commercial and industrial new construction as well as renovation work. Match the bit diameter to the anchor you are setting, not to the fastener.
5) For a maintenance crew standardizing on one drill bit size for conduit strap anchors, which of the two should we stock?
Stock both if you set more than one anchor type. The 1/4 inch x 6 inch (59986) suits smaller strap and box anchors; the 5/16 inch (59987) suits the larger sleeve and wedge anchors commonly used for support hardware. Both share the same SDS shank, so one rotary hammer runs either.
