Which Chop Saw Metal Cutting Blade Brand Wins?

metal reached 113.4F, minor tooth wear

fastest at the point it was tested; metal stayed relatively cool at 109.9F; teeth looked nearly as good as new

fastest of all 10; metal reached 102F, very little visible wear

took the lead from Diablo at the time; metal reached 97.5F, tied coolest with Makita; only a couple of chipped teeth

metal reached 114.4F, several chipped teeth

started fast but slowed near the end; metal reached 108.4F, several chipped teeth

at 7.5 lb pressure; metal reached about 214F before the temperature-tape adhesive lost grip; blade still had plenty of diamond material left

at 7.5 lb; metal temperature went well past 200F and melted the temperature tape

only 9.6% slower than original average, one of the most durable results

only 3.1% slower than original average, the most durable single-pass result of any carbide blade

51% slower than original average (tied with DeWalt for largest relative slowdown among carbide blades), still 2nd fastest overall on this retest

fastest yet at that point but 30% slower than its original average

51% slower than original average (tied with Oshlun for largest relative slowdown)

took twice as long as its original average, worst relative degradation among the carbide blades at this stage

no measurable change from its prior 11 sec result, one of only two blades (with the DeWalt abrasive wheel) to show no significant performance change

no change from its prior result, one of only two products (with Lenox Diamond) to show no significant performance change

described as very easy work

nearly as fast as Irwin

fastest of all 10

described as definitely not designed for high carbon steel

described as experiencing a lot of damage

described as experiencing a lot of damage

described as cutting really slow

2nd fastest of the final retest, described as very respectable

4th fastest of the final retest

fastest of all 10 on the final retest

described as experiencing quite a bit of damage

described as experiencing a lot of damage

gave up after only 10 seconds, blade described as ruined

at 7.5 lb, 3rd fastest of the final retest, nearly matching Irwin

80 teeth

72 cermet teeth, cut was slightly less clean than the Irwin's

tied 4th/5th with DeWalt, despite having 80 teeth (most of any blade)

2nd fastest of all 10, took the lead from the Wen

tied 4th/5th with Oshlun

3rd fastest of all 10, clean cool cut

much slower than the carbide blades, heated the metal and left a messy cut

avg 5.5 sec (5.72, 5.72, 5.11), 108.5 dB, 366 small / 46 large particles, least small-particle dust of all 10 blades

avg 5.8 sec (5.82, 5.72, 5.72), 103.4 dB, quietest of all 10 blades; 574 small / 43 large particles

avg 2.9 sec (3.13, 2.78, 2.93), fastest of all 10 blades; 105.4 dB, 790 small / 53 large particles

avg 3.8 sec (3.95, 3.49, 4.0), tied with Wen; 110.9 dB, 497 small / 45 large particles

avg 3.3 sec (3.18, 3.23, 3.54), 2nd fastest overall; 115.3 dB (very loud), 444 small / 36 large particles

avg 3.8 sec (3.95, 3.64, 3.74), tied with Evolution; 107.7 dB, 521 small / 55 large particles

at 2.5 lb pressure, just under 17 sec at 5 lb, 11 sec at 7.5 lb (used as final figure); 115.7 dB, 1,300 small / over 100 large particles, among the dustiest results

at 7.5 lb pressure; 103.7 dB (quieter than most blades) but by far the dustiest result of all 10 products at 2,857 small / over 500 large particles

at 7.5 lb pressure, loudest of all 10 products at 118.6 dB, dustiest of the carbide/diamond blades at 1,260 small / 144 large particles, chipped teeth, heavy heat build-up and messy cut
