Metallics SDS11821 – Frequently Asked Questions
1) Will the Metallics SDS11821 bit fit my SDS-Plus rotary hammer?
Yes. The SDS11821 is an SDS+ shank bit, so it drops into any SDS-Plus chuck without an adapter or key. It will not fit an SDS-Max tool, and it will not run correctly in a standard three-jaw keyed or keyless drill chuck, which cannot grip the slotted SDS shank or transmit the hammer action.
2) Can I use the SDS11821 for electrical conduit penetrations through concrete walls?
Yes, that is a common use. Metallics catalogs the SDS11821 as an electrical-trade item, and the 21 inch length clears typical poured walls and slabs so you can core a sleeve path for conduit from one side. Hole diameter is fixed at 1-1/8 inch, so size your conduit or sleeve to that bore.
3) Will a 1-1/8 inch SDS-Plus bit this long work in a small cordless rotary hammer?
Mechanically it will chuck up in any SDS-Plus tool, but 1-1/8 inch is at or near the top of the capacity range for compact SDS-Plus hammers, and a 21 inch bit at that diameter asks a lot of a small tool. Check your hammer's rated maximum bit diameter in concrete before running it, or step up to a mid-size SDS-Plus hammer for steady progress.
4) What part number do I order for the Metallics 1-1/8 inch long SDS+ hammer bit?
Order Metallics SDS11821. That single part number covers the 1-1/8 inch diameter by 21 inch SDS-Plus hammer drill bit; there are no finish, length, or shank variations to specify.
