Review on LENOX 13 Piece Bi Metal Hole Saw Set: Ultimate Metal Cutting Precision by Jeff Henkhaus

Smooth weld. Excellent cut. The 13 piece Lenox set DOES NOT include a 2 1/8" saw. Having too much time compared to not enough brains, I also bought a set of Milwaukee and DeWalt. their design and use. Milwaukee- and DeWalt sets have a noticeable weld which may contribute to a less clean cut and more force/wiggle during use Nozzles/arbors/arbors are very similar for all smaller holes Saws - Threaded On larger saws the mounting system appears to be larger to be the same between lenox and milwaukee with a spring loaded dewalt shaft not sure i like it maybe with the added use of dewalt the mandrel system will prove more reliable with less ability to off the saw to "get out" (although that's not the case with Lenox or Milwaukee Snap systems.) The DeWalt mandrel needs to "hold on until you get there". The DeWalt case is the most compact and in the most to find saws. Also, DeWalt saws have a depth that matches Lenox. Milwaukee, flattest (see fig.). The Milwaukee case's foldable handle makes it easy to carry/store, but it doesn't have the dual metal side latches of Lenox and DeWalt. The Milwaukee plastic fastener has worked well on a variety of drill bits, so this is not an issue. What I don't always like is the nesting of different sized saws. Keep them separate and compartmentalized for ease of use, organization, and (I think) durability. The Milwaukee teeth have the most lateral movement, which can result in better wood chip recovery and/or less heat build-up. They all have a stepped tooth shape, but the uniformity and consistency of the tooth shape belongs to DeWalt. However, Lenox saws cut very well. Next up is the new, relatively recently released Diablo set and its quick-change, easy-to-remove rod. I have very high hopes for the Diablo (Freud) set which I haven't bought yet but I'm going to be a Hole Punch Scientist so it's going to happen. I should have more brains than time and money. For now though, I need to be plump for Lenox.
