Review on 🔩 Milwaukee 49-56-0213: Premium 4 Inch Hardened Hole Bit for Efficient Drilling by Richard Lamptey

I needed a 4" bit to mount some recessed lights. projects. This 4" was just as good as the others. Specific comments:** The website description says "imported". A few lines later it says "Made in USA". This discrepancy is explained on the blister pack, on the 'Made in USA' stands for imported materials', meaning both imported and domestic. ** The hole saw pictured online was different than the one you received. See image. The geometry of the slots for ejecting the cutting discs is different. does it matter? no Both geometries work well - better than the previous straight slot design. ** This hole saw is designed and rated for cutting metal. No problem with my plasterboard ceiling - nice clean cuts. **Although I have several Milwaukee arbors, I used a Milwaukee Hole Saw on Shaft DeWalt Same Threads Same Locking Pattern DEWALT DW1803 Heavy-Duty 7/16" Quick Change Shank (fits hole saws from 1-1/4" to 6") ** You will only receive a hole saw y, without mandrel, which is exactly as the picture and the description. ** For cutting drywall I was able to mount this hole saw to a Hitachi 3/8 inch cordless drill. This is for drywall. For cutting something harder, even thin board, I would use a 1/2 inch bit. The 4" hole saw has plenty of torque both when starting and stopping. Even if you don't burn out the motor on a smaller drill, you can ruin the clutch just when starting and stopping. I found a small time plug that works with drywall to extract cut slices. Instead of taking them out, just twist the drill bit once or twice while pointing the drill bit down. Drywall dowels fall out easily. Lubrication is essential when cutting metal, but not necessary when cutting. With wood a few drops of wax or paraffin can speed up the cut and reduce heat build-up.
