5/16 inch SDS Plus bit for masonry

The Westward 22UW05 is a carbide-tipped hammer drill bit built for SDS Plus rotary hammers. Its four-cutter geometry targets brick, block and concrete in professional and serious DIY installations. The straight shank design fits directly into compatible chucks without adapters.

10 inch drilling depth with 12 inch length

The 12 inch overall length provides a maximum drilling depth of 10 inches, giving ample reach for through-holes in thick walls or deep anchor embedment. Beyond that depth the flutes cannot clear dust effectively and the bit will bind. The 5/16 inch diameter suits common mechanical anchors and rebar dowels.

Bright uncoated finish ships free over 75

The bright uncoated surface resists no corrosion, so the bit should be wiped dry and stored indoors to avoid rust. Orders of 75 or more qualify for free shipping direct from the supplier, reducing per-unit cost on larger jobs. No case, lubricant or centring guide is included.

Questions about this item

Will the 5/16" SDS Plus shank fit my older rotary hammer that uses standard SDS Plus bits?

Yes, the 25/64" shank diameter matches the SDS Plus standard so it locks into any SDS Plus chuck.

How can I confirm the 4-cutter head is drilling straight and reaching the 10" maximum depth?

The bit should advance smoothly without wobble; measure the hole depth against the 12" overall length to verify the 10" drilling capacity.

Does the box include any lubricant or adapter, or is the bright uncoated carbide bit the only item?

Only the 12" long 4-cutter SDS Plus bit is supplied; no grease, case or adapter is included.
