Milwaukee 12PC QUIK-LOK HOLE DOZER Bi-Metal Hole Saw Kit (49-22-4702) vs LENOX 7PC Contractor's Hole Saw Kit (1815140)
Which should you buy? Our verdict on both, pulled from our full The Best Hole Saws: 4 Compared (and One to Skip) comparison.
Milwaukee is the only one of these four that publishes a depth of cut, a recommended RPM by material and a warranty on the same product, and its QUIK-LOK arbor set is documented to fit industry standard threaded hole saws from other brands. The LENOX kit gets you the same two thread ranges for less by shipping two conventional arbors instead of one clever one.
Milwaukee 12PC QUIK-LOK HOLE DOZER Bi-Metal Hole Saw Kit (49-22-4702)
Buy itThe only kit here whose maker publishes a depth of cut, an RPM figure per material and a warranty, on an arbor documented to drive other brands' saws.
- Milwaukee publishes a 1-5/8 in. depth of cut on every bi-metal HOLE DOZER size, plus RPM figures for stainless steel, mild steel, cast iron and aluminium on each size page.
- The QUIK-LOK arbor set carries a small thread adapter, a large thread adapter and a large thread pin adapter, and Milwaukee states it fits all industry standard threaded hole saw sizes, types and brands.
- Backed by a Limited Lifetime Tooth Break Warranty covering tooth breakage or fracture caused by defects in material or workmanship.
- 3.5 TPI is a coarse constant pitch, which is a compromise on thin sheet metal where a finer tooth is easier to keep engaged.
- The warranty covers tooth breakage from defects only and excludes misuse, alteration, abuse and normal wear.
- The saws top out at 2-1/2 in. in this kit, so larger openings mean buying individual cups.
LENOX 7PC Contractor's Hole Saw Kit (1815140)
Buy itFive saws and both arbors you actually need, from the maker that publishes the most complete public speed chart in the category.
- Ships with both a 5L and a 2L arbor, so it covers the 9/16 in. to 1-3/16 in. range and the 1-1/4 in. and larger range without a second purchase.
- LENOX publishes recommended RPM tables by diameter and material for bi-metal, carbide-tipped, carbide grit and diamond saws in its own catalogue.
- The Speed Slot staircase design puts wide slots low on the cup with multiple leverage points, so a screwdriver gets under the plug.
- LENOX does not publish a cutting depth or a tooth pitch for these saws, only that they are 10 percent taller than the previous generation.
- The LENOX product page for this kit states it is not eligible for any warranty.
- Two conventional arbors means a hex key and a threaded change, not a one-handed swap.
