Milwaukee 48-17-3070 – Frequently Asked Questions

1) Can the Milwaukee 48-17-3070 core bit be used dry?
No. The 48-17-3070 is a wet core bit, built to run with water feeding the diamond segments to cool them and hold down dust. Running it dry will cook the segments. If you need to core without a water supply, you want a dry diamond core bit instead.
2) What size hole does the Milwaukee 48-17-3070 cut, and will a 7 inch core clear a 6 inch sleeve?
It cuts a nominal 7 inch diameter core. That is the usual choice when you need to pass a 6 inch pipe or sleeve through concrete, since the 7 inch bore leaves room for the sleeve wall and grout. For the hole itself, order by the 7 inch trade size.
3) Can I run the 48-17-3070 in a handheld rotary hammer?
No. It is set up for wet coring drill rigs, not a handheld hammer drill. A 7 inch diamond bit in wet concrete needs the rigidity, the water feed, and the controlled feed pressure a core rig gives you. For a handheld tool, use a dry-cut carbide or diamond hole saw in the smaller sizes.
4) What materials will a Milwaukee diamond wet core bit cut?
Concrete, masonry and block, and other dense building substrates. The cutting edge is diamond segmented, which is what lets it work through hard aggregate rather than just block. It is not a wood or metal hole saw.
5) Is this the right bit for coring a 7 inch opening for HVAC or electrical conduit through a concrete wall?
Yes, that is exactly the use. Plumbing, electrical and HVAC penetrations through concrete and masonry are the stated applications, and the wet-cutting design keeps silica dust down, which matters when you are coring inside an occupied building.
6) Does the 48-17-3070 come with an arbor, adapter, or pilot?
The 48-17-3070 is sold as the core bit alone in the 7 inch size. Anything else your setup needs, the rig, the water feed, and any thread adapter between your rig spindle and the bit, is ordered separately.
7) What is the Milwaukee part number for the 7 inch diamond wet core bit?
48-17-3070 is the Milwaukee catalog number for the 7 inch premium diamond wet core bit. Use that number when matching a replacement for a rig already on the truck, since Milwaukee's wet core bits run as separate part numbers per diameter.
