Milwaukee 48-20-7401 – Frequently Asked Questions
1) Will the Milwaukee 48-20-7452 bit fit my SDS Plus rotary hammer?
Yes. The 48-20-7452 uses an SDS Plus shank, so it drops into any SDS Plus rotary hammer chuck tool-free with no keyed chuck or adapter. It will not fit an SDS Max or spline-drive hammer, and it is not meant for a standard three-jaw drill chuck.
2) What sizes does the Milwaukee SDS Plus 2-cutter hammer bit come in?
Three diameters: 5/32 inch (48-20-7401), 3/8 inch (48-20-7452), and 3/4 inch (48-20-7066). The 5/32 is the size most used for small tapcon-type masonry screws, 3/8 is the common anchor and conduit-strap size, and 3/4 handles larger wedge anchors and sleeve work.
3) How deep a hole can the 3/8 inch 48-20-7452 drill?
The 48-20-7452 is a 3/8 inch diameter bit with a 6 inch flute length and 8 inch overall length, so usable drilling depth is up to the 6 inch flute. That covers most block, brick, and poured concrete wall thicknesses as well as through-drilling for conduit. If you need to pass through anything deeper than 6 inches, step up to a longer SDS Plus bit.
4) Is a 2-cutter SDS Plus bit the right choice, or do I need a 4-cutter?
A 2-cutter head like this one has a single carbide tip across the diameter and bores cleanly in plain concrete, concrete block, and brick. Where 2-cutter bits struggle is heavily reinforced concrete, since hitting rebar can knock a two-tip head off center. For rebar-heavy structural pours, a 4-cutter head is the better pick. For anchor holes, conduit penetrations, and plumbing rough-in in block and brick, the 2-cutter is what most crews run.
5) Can I use this Milwaukee bit in a hammer drill instead of a rotary hammer?
No. The shank is SDS Plus, which only locks into a rotary hammer's SDS Plus chuck. A standard corded or cordless hammer drill with a keyless chuck takes round or hex-shank masonry bits instead. Running masonry work with a rotary hammer and this bit is also faster through concrete than a hammer drill.
6) Is this bit suitable for drilling through tile, wood, or steel?
No. This is a carbide-tipped rotary hammer bit for concrete, masonry, and brick. Hammer action will chip glazed tile and it is the wrong tool for wood or metal. Keep it on anchor holes, conduit and pipe penetrations, and block or brick drilling.
7) What is the Milwaukee part number for the 3/4 inch SDS Plus 2-cutter bit?
The 3/4 inch size is Milwaukee 48-20-7066. The same 2-cutter SDS Plus family also runs as 48-20-7401 in 5/32 inch and 48-20-7452 in 3/8 inch, which is useful if you are standardizing a bit kit across a crew or stocking a service van.
