1DeWalt$306.55 seconds, second place behind the CB/KSEIBI; four years ago this same brand cut through mild steel in around 8 seconds3.29 seconds, second fastestdrilled completely through to the 7/8 in hole in 7.79 seconds, the fastest full completion of the seven brands that finished this hole2.67 seconds, second fastestmade the biggest hole at that point in the test at 0.64 in, though with some visible wear to the chiselonly lasted about 2 seconds, with the leading edge of the flutes and the chisel in very bad condition afterward; reached only 1.67 mm of depth, described by the narrator as last place on this specific test
2TEMO$30, the same price as the DeWalt7.53 seconds, third place; four years ago this same brand made the pilot hole in 11 seconds4.74 secondscame to a stop at 3/4 of an inch, did not fully complete the 7/8 in hole3.18 seconds, third fastestlargest hole at that point in the test at 0.74 in, and the bit still looked as good as new afterwardthe only one of the 20 brands to completely drill through the AR500 plate, at around 18 seconds, while still in very good condition
3Klein Tools$34just over 12 seconds; four years ago this same brand was one of the slowest in the lineup at 34 seconds6.34 seconds (transcript renders this as '6.3 4', a caption-split decimal kept verbatim and treated as 6.34)drilled completely through to the 7/8 in hole in 11.15 seconds, third place among the seven brands that completed this hole3.55 secondsleft the largest hole at that point in the test at 0.77 in, with a little more wear and tear than the Teemo; finished 2nd overall in final hole-size ranking at 0.77 in behind Milwaukee's 0.785 infinished in about 18 seconds with some visible wear to the chisel and leading edge of the flutes, reaching 10.21 mm depth, described as quite a bit better than average
41WANUE$3012.23 seconds, described as making pretty slow progress compared to CB, DeWalt, and Teemo6.75 secondscould not quite finish the job, coming to a stop at 9/16 of an inch4.27 seconds0.59 in hole, looked nearly as good as new (nearly as good as the Teemo)lasted about 15 seconds before running out of steam with quite a bit more wear and tear than the Teemo; reached 11 mm depth, good enough for second place overall behind the Teemo's full penetration
5Sharptool$18just over 11 seconds, took the lead at that point in the videoaround 6.5 secondsran out of steam early at 0.68 in, did not complete the 7/8 in hole6.65 seconds, fastest at that point in the test0.625 in (5/8 in) hole, with a small amount of wear on the chisel pointstopped making progress at around 23 seconds, reaching 10.81 mm depth, described as very good and finishing third overall behind Teemo (full penetration) and 1WANUE (11 mm)
6Hercules$40 for two bits, or $20 each8.57 seconds, took the lead at that point; four years ago this same brand needed 17 secondsvery close to 6 seconds, the fastest at that point in the testcame to a stop at approximately 0.5 in (transcript shows a garbled fraction rendered as 'a/2 in', kept verbatim and read as roughly 1/2 in)3.6 seconds, took the lead at that point0.56 in hole, still in pretty good conditionstarted off strong but stopped making progress at around 19 seconds with quite a bit of wear and tear, reaching 10.16 mm depth, almost as good as the Sharptool
7Norseman$2710.17 secondsjust under 6 secondsdrilled completely through to the 7/8 in hole in 10.17 seconds, third place among the seven brands that completed this hole5.1 seconds, but barely made progress before the stainless steel became too hardhole size just over approximately 0.5 in (transcript shows a garbled fraction rendered as 'a/2 in'), bit still in very good conditiondescribed as 'immediately squealing like a pig' but kept going, stopping at around 19 seconds; reached 9.03 mm depth, good enough for third place at that point in the narration
8PIT$19very close to 13 seconds, second place behind the Sharptool7.73 secondscame to a stop at approximately 0.5 in (transcript shows a garbled fraction rendered as 'a/ in')6.55 seconds, slightly faster than the Sharptool0.58 in hole, chisel point in the best shape of any brand yetstopped making progress at around 12 seconds with quite a bit of wear and tear, reaching 7.4 mm depth
9Toolant$5312.34 seconds, described as not making very fast progress compared to many less expensive brandsjust over 7 seconds, trailing the Greenleealso trailed the Greenlee here, coming to a stop at 0.68 in6.24 seconds, a little slower than average0.56 in hole, with some wear to the chiselstarted off strong but stopped making progress at around 10 seconds with a lot of wear and tear on the chisel, reaching 7.02 mm depth, described as a pretty good amount of progress
10OXMUL$22just over 8 seconds, took the lead at that point4.43 seconds, third fastest pilot hole in this test (per the closing recap for this segment)outperformed the Hercules, coming to a stop at just over approximately 0.5 in (transcript shows a garbled fraction rendered as 'a/2 in')3.39 seconds, faster than the Hercules0.54 in hole, still in very good conditionshort life at around 11 seconds, chisel described as pretty dull afterward, reaching only 6.86 mm depth
11KSEIBI$274.17 seconds, about twice as fast as the OXMUL, very impressive, new fastest time at that point2.26 seconds, fastest pilot hole of this segmentthe spiral flute design pulled the bit into the cut too fast and it ran out of steam at 0.44 in1.27 seconds, by far the fastest of all 20 brands on this test0.61 in hole, still in very good conditionstarted off strong but became stuck quickly (the flute design pulled the bit into the work piece too aggressively); the narrator released it several times but it kept sticking; reached only 5.86 mm depth, the least progress of any brand up to that point in the narration
12Milwaukee$150 for three bits, or $50 eachjust over 30 seconds; four years ago this same brand was pretty fast at just 10 seconds, a significant slowdown this timenot separately stated in the transcriptnot stated in the transcript3.23 seconds, almost as fast as the DeWaltmade the largest hole of any brand overall at 0.785 in, though with some wear and tear to the chisel and leading edge of the flutesquick to fail, at around 5 seconds, with significant damage; reached only 2.8 mm depth
13Greenlee$538.41 seconds, a little faster than averageover 6 secondsdrilled completely through to the 7/8 in hole in 9.39 seconds, second place among the seven brands that completed this hole4.17 seconds0.61 in hole, with quite a bit of wear and tearfinished after about 2 seconds with lots of damage to the chisel, reaching only 1.26 mm depth, a pretty shallow hole
14Snap-on Blue Point$123 before shipping, handling, and tax, or $160 with it15.48 seconds (transcript shows a stray '%' character after this number, treated as caption noise rather than a real value)8.2 seconds, the same speed as the Irwindrilled completely through to the 7/8 in hole in 20.18 seconds7.63 seconds, slower than average0.44 in hole, smaller than average, with more wear and tear than most other brandsstarted well but was out of steam at around 20 seconds with the chisel and leading edge of the flutes pretty much worn out, reaching 5.3 mm depth, around half the progress of the $18 Sharptool
15Irwin$8transcript states '2.79' seconds while also describing it as 'still pretty slow'; four years ago this brand drilled the pilot hole in 30 seconds. The 2.79 figure is inconsistent with the 'still pretty slow' description and is likely a dropped leading digit (plausibly closer to 20+ seconds); kept verbatim and flagged rather than corrected8.2 secondscame very close to finishing, stopping at 0.81 in (just short of the 7/8 in / 0.875 in target)not testedthe stainless steel was too hard for the Irwin; chisel point left flat and damaged, no hole completednot tested; excluded because it could not drill through stainless steel
16Neiko$9just over 14 seconds; four years ago this same brand was one of the slowest at over a minutejust over 7 secondsdrilled completely through to the 7/8 in hole in 21.8 seconds, one of only seven brands to complete this hole, though the slowest of the sevennot testedperformed reasonably well overall but the stainless steel proved too hard; chisel point left flat and dull, no meaningful hole completednot tested; excluded because it could not drill through stainless steel
17Diablo Freud Diablo$35just over 30 seconds; four years ago this same brand drilled the pilot hole in 18 seconds, a significant slowdown this timejust over 9 secondsdrilled completely through to the 7/8 in hole in 17.29 seconds (transcript shows a stray '%' character after this number, treated as caption noise)not testedthe stainless steel proved way too much for the Diablo; narrator attributes this to a poorly shaped chisel pointnot tested; excluded because it could not drill through stainless steel
18Mac Tools$10024 seconds, one of the slowest in the lineup11.77 secondsalmost crossed the finish line but came up short at 0.82 in, just under the 7/8 in targetnot testedstruggled and was unable to drill a hole, with quite a bit of visible wear and tearnot tested; excluded because it could not drill through stainless steel
19EZARC$3325.82 seconds, one of the slowest in the lineup11.87 secondscame to a stop at just over 1/2 innot testedthe stainless steel was way too hard for the EZARC; narrator says the chisel does not seem to have the right geometry for cutting efficientlynot tested; excluded because it could not drill through stainless steel
20Anfrere$7, the least expensive of all 20 brands testedjust over 1 minute, making very slow progress, the slowest brand in this testtranscript reads '32.441748 in hole', likely a merged/garbled figure combining the pilot hole time (around 32.44 seconds) and a partial hole diameter reached; kept verbatim rather than split apart, since the true boundary between the two numbers is not clearsee above; final hole size not reliably determinable from the transcriptnot testedunable to drill into the stainless steel at all; the steel became too hard from heat and the chisel point was left flat and, per the narrator, 'pretty much ruined for a budget step' bitnot tested; excluded because it could not drill through stainless steel

How it was tested

  • mild steel pilot hole (3/16 in step) speed test under 54 lbs of downward force at 990 RPM
  • Rockwell-style hardness scratch test on the tester's own pick, used only as background context, not a per-brand metric
  • medium hardness steel (about half the thickness of the mild steel) pilot hole speed test, then continued drilling to a 7/8 in hole where possible
  • stainless steel pilot hole speed test, then continued drilling as far as possible, noting final hole size and chisel wear or failure
  • AR500 armor plate (extremely hard steel) test under about 200 lbs of downward force with cutting oil, for the 14 brands that survived the stainless steel test; measuring time survived and hole depth in mm, or full penetration

the DWT came out on top with an average finish at Fourth Place
