What this drill bit does

The Westward 22UW59 is a 4-cutter hammer drill bit designed for SDS Max rotary hammers. It drills 3/4 inch holes in concrete, masonry and stone. The carbide-tipped head uses four cutting edges to break up material efficiently. Professional contractors and serious DIY users choose it for anchor installation and through-hole work.

Heat and wear in use

The bright uncoated carbide runs without a surface coating that could wear away. Four cutting edges spread the load, reducing heat build-up on any single tip during prolonged drilling. The straight shank transmits impact energy directly from the SDS Max drive. No lubrication or cooling system is required for normal operation.

The fit that matters

The shank diameter is 45/64 inch and the overall length is 13-1/2 inches. Maximum drilling depth reaches 11 inches. If your SDS Max tool accepts this shank and your hole depth stays within 11 inches, the bit will seat and drill correctly. Builders needing deeper holes or a different shank system should look elsewhere.

Questions about this item

How do I fit the 45/64 in shank into my SDS Max rotary hammer?

Align the splines on the 45/64 in shank with the SDS Max chuck, push until it clicks, then give a firm tug to confirm it is locked before drilling.

When will the carbide cutters need attention?

The four carbide cutters stay sharp through many holes in concrete; resharpen or replace the bit once the tips show visible wear or drilling speed drops noticeably.

What stops me from drilling deeper than 11 in?

The flute length limits effective debris removal to the 11 in maximum drilling depth; going deeper packs dust in the flutes and stalls the bit.
