3Irwin$8.4214 teeth, bimetal, no mandrel includednot testedaround an 8 on the Mohs pick scale23 seconds, tied with DeWalt Carbide for fastest at that stage, only a couple teeth showed visible wearextremely fast but hole quality did not look very good, size about 3/64 inch too large30 seconds, managed metal shavings wellstopped making progress after about 10 seconds, armor plating was too much for it, all teeth ended up pretty dull
4NGE$7.995 teeth, carbide, includes the mandrelChinascratched by a number eight Mohs pick, not high quality carbide by the host's standard35 seconds, one carbide tooth experienced a little damagepretty decent, hole size just under 1 inch36 seconds, managed chips well, no compressed air neededdid not fully cut through the work hardened armor, but almost drilled all the way through, best depth of the bimetal/entry-level saws; 4 of 5 carbide teeth had mild to moderate damage
5Bosch HB100$10.4513 teeth, bimetal, no mandrelpackaging claims USA, Switzerland, or China; the actual hole saw itself is stamped made in Chinaaround an 8 on the Mohs pick scale, same as Milwaukee Hole Dozer48 seconds, started fast but slowed about 15 seconds in, held up about the same as Irwinvery clean cut, only 1 and 1/128 inch over an inch, extremely good job29 seconds, only 5 seconds slower than Morse, great chip displacementstopped making progress after about 10 seconds, best of the three bimetal saws (beat Milwaukee Hole Dozer and Irwin)
6Lenox$10.9813 teeth, bimetal, includes the mandrelUSA with global materialsaround an 8 on the Mohs pick scale29 seconds, held up really well with only minor tooth wearvery good, only over by 1/64 inch1 minute 17 seconds (77 seconds), did not disperse metal chips as well as some other brandsstopped making progress after about 5 seconds, performed about the same as Irwin, all teeth showed significant dulling
7DeWalt 2X 2X$10.9914 teeth, bimetal, no mandrelUSA with global materialsaround an 8 on the Mohs pick scale39 seconds, lost momentum about halfway through, only minor tooth wearquality of finish looked very good, described as extremely accurate, no exact fraction given140 seconds (2 minutes 20 seconds), does not displace chips as efficiently as some other brands despite being a terrific hole sawunlike the other bimetal saws, continued cutting after 10 seconds and did not slow until around 25 seconds, did as well as Morse for a bimetal, teeth ended up in better condition than the other bimetal saws
8TCT Carbide$12.886 teeth, includes the mandrelChinabetween an 8 and a 9 on the Mohs pick scale30 seconds, only minor visible wear on one toothvery nice looking finish, precision impressive, only off by 1/128 inch35 seconds, terrific chip displacementcut well over a minute before stopping, best result up to that point in the video, almost made it all the way through, 4 of 5 teeth remained in very good condition
9Diablo$14.858 teeth, tooth hardness around a 9, no mandrel included, requires the Snap-Lock Plus mandrelassembled in China with Swiss componentsnot tested31 seconds, got stuck several times slowing it down slightly, teeth still had paint on them and looked as good as newfairly fast but quality of cut not quite as good as some other brands, size off by about 1 and 7/128 inch34 seconds, wide tooth path like NGE and TCTshredded the armor plating for nearly 2 minutes before stopping, the best AR500 result in the whole video, better than TCT, about two thirds of teeth still in very good condition
10DeWalt Carbide Carbide$39.434 teeth, includes the mandrelTaiwannot scratched by a number nine Mohs pick, very high quality carbide23 seconds, tied with Irwin for fastest, briefly got stuck at the start, no visible chipping or wear, looked as good as newfinish definitely the best yet at that point in the video, extremely accurate25 seconds, terrific chip displacement despite a wider path than the bimetal sawsstarted off very strong, gradually lost momentum; host calls it the best hole saw for mild and medium steel, but all four carbide teeth broke on the AR500 armor plate
11Drill Hog USA$39.994 teeth, includes the mandrelnot testednot scratched by a number nine Mohs pick, very high quality carbide30 seconds, held up really wellextremely smooth cut, only 1/128 inch over an inchgreat chip displacement like DeWalt Carbide, but the transcript's number is garbled: 'it wasn't quite as fast as the DeWalt at seconds' drops the actual seconds value, so this figure is omitted rather than guessedstarted off very strong like DeWalt Carbide, gradually lost momentum, did not quite cut all the way through but did better than DeWalt Carbide, all four teeth experienced some damage
12DeWalt Impact Ready Impact Ready$15.4130 teethUSA with global materialsaround an 8 on the Mohs pick scale39 seconds, did not start off as strong as some other brands given its high tooth count, only minor tooth wearsmoothness of the cut probably the best yet at that point in the video, hole size 1 and 3/128 inch44 seconds, struggled with chip displacement and needed compressed air assistance several timesnot tested
13Milwaukee Shockwave Impact Ready$18.5724 teeth, includes the mandrelTaiwanbetween a 7 and an 8 on the Mohs pick scaledid not finish; started strong, stopped making progress around 30 seconds, eliminated and did not advance to the hard steel or AR500 testsdid not quite finish the cut, but was very closenot testednot tested
14generic 5-piece hole saw kit$14.6917 teeth, includes its own mandrelChinaonly a 6 on the Mohs pick scale, far softer than the other brands2 minutes 35 seconds (155 seconds), all teeth showed more wear than the other brands tested up to that pointextremely slow but provided a very clean finish, hole size 1 and 1/128 inchdid a poor job displacing chips and was unable to cut through the steel, effectively eliminatednot tested

How it was tested

  • cut time and tooth wear through 3/16 inch mild steel at 250 RPM and about 85 lb of downward force
  • hole size and finish accuracy on the mild steel cut, measured against the nominal 1 inch diameter
  • cut time and chip dispersal through hardened 1095 knife blade steel with cutting oil and extra downward force
  • cut depth, progress, and tooth condition attempting to cut through AR500 armor plating
  • Mohs hardness pick scratch test on each hole saw's teeth or carbide

All three of the brands that I really liked are under $10 and performed very well especially the US made Morse brand with the carbide teeth. It did an amazing job averaging number one for cutting speed on the first two types of steel that we tested.

Data notes and caveats

14 distinct hole saw brands are tested (matching the host's opening line 'we've got 14 brands to test'), but the video description's prose brand list and its affiliate link list both name only 12, omitting NGE and an unbranded generic 5-piece kit entirely even though both are fully tested with price, tooth count, and hardness data; flagged in those two products' notes rather than assumed to be errors. Two brands are eliminated partway through: Milwaukee Shockwave (impact ready) failed to finish the first mild steel cut and does not appear again, and the unbranded generic kit failed to cut through the hard steel test and likewise does not appear in the AR500 test, though no explicit skip statement was given for it. DeWalt Impact Ready is explicitly excluded from the AR500 test on camera because its arbor and drill are a single integrated unit, a genuine stated omission, not a caption gap. One brand mislabel was resolved by testing order: a hard steel test sentence names 'the DeWalt Shockwave' at 44 seconds, which cannot be Milwaukee Shockwave since that product was already eliminated, so the time was assigned to DeWalt Impact Ready by subject continuity. Drill Hog's hard steel cut time is missing from the transcript due to an apparent dropped number ('wasn't quite as fast as the DeWalt at seconds') and is recorded as omitted rather than guessed. The closing verdict names three liked brands, all under 10 dollars (MK Morse, Milwaukee Hole Dozer, Irwin), explicitly framed as a value message even though more expensive brands (Diablo, TCT Carbide, DeWalt Carbide, Drill Hog) scored as well or better on the hard steel and AR500 tests; winner and runnerUp are set to the top two of that closing list, with Irwin as the third liked brand documented in its own notes since the schema has no third slot.
