  • 1 in carbide tip drills large holes cleanly

1-Inch SDS Max 4-Cutter Bit

This Westward 22UW65 hammer drill bit uses an SDS Max shank for heavy-duty rotary hammers. The 1-inch diameter and 22-1/2 inch overall length suit deep-hole work in concrete and masonry. A four-cutter carbide tip channels dust away from the cutting edges. It is built for trade professionals who drill large anchor or through-holes daily.

Replaces Worn Single-Cutter Bits

A dull or chipped single-cutter bit slows progress and overloads the hammer mechanism. Stepping up to the four-cutter geometry restores drilling speed and reduces vibration on the same machine. The upgrade pays off when you run dozens of holes per shift or hit rebar regularly. Occasional users drilling only a few holes a year will not see the same return.

Fits SDS Max Rotary Hammers

The 45/64 inch shank diameter locks into any SDS Max chuck without adapters. The bright uncoated finish resists galling during repeated bit changes. Maximum drilling depth reaches 20 inches, leaving room for thick base plates or double walls. Builders needing larger diameters or a different shank system must choose another bit.

Questions about this item

What SDS Max rotary hammer will accept the 45/64 in shank on this 22UW65 bit?

Any SDS Max rotary hammer uses the 45/64 in shank, so the bit locks directly into the tool without an adapter.

How do you seat the bit fully so the 4-cutter carbide tip reaches the 20 in maximum drilling depth?

Insert the shank until it clicks twice, then pull back firmly to confirm the locking balls engage before starting the hole.

When should the 1 in carbide tip be replaced or resharpened?

Replace or resharpen when the tip no longer cuts cleanly to the 20 in depth or the flutes clog with concrete dust.
