Every size in this family shares a copper braze tip for high heat resistance during sustained drilling, a chrome-vanadium spring steel shaft for extended bit lifetime, and a 1/2 in. straight shank sized to fit hammer drills equipped with a 3-jaw or Jacobs chuck. A double-ground, extra-deep flute clears debris quickly across the line, keeping the drilling path visible from the smallest to the largest size in the family.

Irwin IRW-326020 – Frequently Asked Questions

1) Will the Irwin 326020 masonry bit fit my hammer drill chuck?
The shank is a 1/2 inch straight shank, so it chucks into a hammer drill with a 3-jaw or Jacobs chuck. It is not an SDS-plus or SDS-max bit, so it will not drop into a rotary hammer with an SDS spindle. If your drill takes SDS shanks, you need a different bit family.
2) Can I use this Irwin bit in rotary-only mode, or does it need hammer action?
It is built for rotary percussion drilling, meaning hammer mode in concrete, brick, and masonry. Spinning it rotary-only in masonry will dull the carbide tip without making much progress. The copper braze tip handles the heat from sustained hammering, and the chrome-vanadium spring steel shaft takes the repeated impact.
3) Will this bit drill through rebar if I hit it in a concrete slab?
No. This is a masonry percussion bit with a brazed carbide tip for concrete, brick, and masonry. Striking rebar will chip or destroy the tip. If you expect reinforcement, use a rebar cutter bit or relocate the hole.
4) How deep a hole can I get with these Irwin masonry bits?
Both orderable sizes are 8 inches overall length, and some of that is consumed by the shank sitting in the chuck, so usable drilling depth is less than 8 inches. The deep, double-ground flute clears dust as you go, which matters on deeper holes where packed spoil is what stalls progress.
5) Does the Irwin 326020 come as a single bit or in a set?
It ships as an individual bit, not a multi-size kit. Each size is ordered separately by its own part number, so a crew standardizing on two anchor diameters orders both the 5/8 and the 3/4 inch bits.
