First things First, this is not an equal comparison of two identical products. Looks are deceiving with these new hole saws because while they look very similar they function very differently and are also priced very differently. The only reason we even are comparing the two products is because a lot of people that are looking at these as equal products. Hopefully this post will help highlight some of the similarities and differences of these two products.
The Milwaukee Big Hawg is primarily a wood hole saw. The pilot is a 3/8” spade like bit and the teeth are hardened steel. While an occasional nail will not damage the saw it is not intended for metal, concrete, fiber board or any other materials. The advantage over a bi-metal hole saw is that it is faster, longer lasting, much easier to get the wood core out as well as easier to sharpen. The advantage over self-feed bits it that they are much cleaner (far less shavings) and will last longer, up to 600 holes between sharpening.
The Bosch Carbide Hole Saw has a drill bit pilot and is made to go through a wide range of materials including: cinder block, metal, cement board, wood and many other materials. The tips are diamond ground carbide and extremely tough.
At first glance the Bosch Carbide looks like the superiors product and it is but the price tag is also double that of the Milwaukee Big Hawgs. Comparison price on a 2-1/8” hole saw: Bosch $55.40 vs. Milwaukee $26.32. While both Hole Saws made it through the wood test in almost identical times the Milwaukee would obviously be the smarter choice at half the price. However if you want a hole saw that is going to do more than cut wood do not buy the Big Hawg. We tested the Milwaukee on all the other materials in the video but basically ruined the pilot bit and damaged the saw by doing so.
Hopefully this post and video will help you determine the right hole saw for you. There are also many hole saw kits from Bosch and Milwaukee listed on OhioPowerTool.com.
