only 2 seconds slower than Irwin, very minor wear on 2 teeth

tied with DeWalt Carbide for fastest at that stage, only a couple teeth showed visible wear

one carbide tooth experienced a little damage

started fast but slowed about 15 seconds in, held up about the same as Irwin

held up really well with only minor tooth wear

lost momentum about halfway through, only minor tooth wear

only minor visible wear on one tooth

got stuck several times slowing it down slightly, teeth still had paint on them and looked as good as new

tied with Irwin for fastest, briefly got stuck at the start, no visible chipping or wear, looked as good as new

held up really well

did not start off as strong as some other brands given its high tooth count, only minor tooth wear

did not finish; started strong, stopped making progress around 30 seconds, eliminated and did not advance to the hard steel or AR500 tests

(155 seconds), all teeth showed more wear than the other brands tested up to that point

quality of cut very good, hole size 1 and 3/128 inch

extremely fast but hole quality did not look very good, size about 3/64 inch too large

pretty decent, hole size just under 1 inch

very clean cut, only 1 and 1/128 inch over an inch, extremely good job

very good, only over by 1/64 inch

quality of finish looked very good, described as extremely accurate, no exact fraction given

very nice looking finish, precision impressive, only off by 1/128 inch

fairly fast but quality of cut not quite as good as some other brands, size off by about 1 and 7/128 inch

finish definitely the best yet at that point in the video, extremely accurate

extremely smooth cut, only 1/128 inch over an inch

smoothness of the cut probably the best yet at that point in the video, hole size 1 and 3/128 inch

did not quite finish the cut, but was very close

extremely slow but provided a very clean finish, hole size 1 and 1/128 inch

around an 8 on the Mohs pick scale

around an 8 on the Mohs pick scale

scratched by a number eight Mohs pick, not high quality carbide by the host's standard

around an 8 on the Mohs pick scale, same as Milwaukee Hole Dozer

around an 8 on the Mohs pick scale

around an 8 on the Mohs pick scale

between an 8 and a 9 on the Mohs pick scale

not scratched by a number nine Mohs pick, very high quality carbide

not scratched by a number nine Mohs pick, very high quality carbide

around an 8 on the Mohs pick scale

between a 7 and an 8 on the Mohs pick scale

only a 6 on the Mohs pick scale, far softer than the other brands

good chip management but not quite as good as Morse

managed metal shavings well

managed chips well, no compressed air needed

only 5 seconds slower than Morse, great chip displacement

(77 seconds), did not disperse metal chips as well as some other brands

(2 minutes 20 seconds), does not displace chips as efficiently as some other brands despite being a terrific hole saw

terrific chip displacement

wide tooth path like NGE and TCT

terrific chip displacement despite a wider path than the bimetal saws

great 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 guessed

struggled with chip displacement and needed compressed air assistance several times

did a poor job displacing chips and was unable to cut through the steel, effectively eliminated

stopped making progress after about 10 seconds, went a little deeper than Irwin, teeth dulled but in better shape than Irwin's

stopped making progress after about 10 seconds, armor plating was too much for it, all teeth ended up pretty dull

did 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

stopped making progress after about 10 seconds, best of the three bimetal saws (beat Milwaukee Hole Dozer and Irwin)

stopped making progress after about 5 seconds, performed about the same as Irwin, all teeth showed significant dulling

unlike 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

cut 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

shredded 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

started 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

started 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
