The measured results

Every number below is read straight from the test. Products are listed in the order they finished.

Mild steel pilot hole time (3/16 in step)

  • 1DeWalt
    6.55 seconds2nd

    second place behind the CB/KSEIBI; four years ago this same brand cut through mild steel in around 8 seconds

  • 2TEMO
    7.53 seconds3rd

    third place; four years ago this same brand made the pilot hole in 11 seconds

  • 3Klein Tools
    just over12 seconds

    four years ago this same brand was one of the slowest in the lineup at 34 seconds

  • 41WANUE
    12.23 seconds

    described as making pretty slow progress compared to CB, DeWalt, and Teemo

  • 5Sharptool
    just over11 seconds

    took the lead at that point in the video

  • 6Hercules
    8.57 seconds

    took the lead at that point; four years ago this same brand needed 17 seconds

  • 7Norseman
    10.17 seconds
  • 8PIT

    very close to 13 seconds, second place behind the Sharptool

  • 9Toolant
    12.34 seconds

    described as not making very fast progress compared to many less expensive brands

  • 10OXMUL
    just over8 seconds

    took the lead at that point

  • 11KSEIBI
    4.17 seconds

    about twice as fast as the OXMUL, very impressive, new fastest time at that point

  • 12Milwaukee
    just over30 seconds

    four years ago this same brand was pretty fast at just 10 seconds, a significant slowdown this time

  • 13Greenlee
    8.41 seconds

    a little faster than average

  • 14Snap-on Blue Point
    15.48 seconds

    (transcript shows a stray '%' character after this number, treated as caption noise rather than a real value)

  • 15Irwin

    transcript 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 corrected

  • 16Neiko
    just over14 seconds

    four years ago this same brand was one of the slowest at over a minute

  • 17Diablo Freud Diablo
    just over30 seconds

    four years ago this same brand drilled the pilot hole in 18 seconds, a significant slowdown this time

  • 18Mac Tools
    24 seconds

    one of the slowest in the lineup

  • 19EZARC
    25.82 seconds

    one of the slowest in the lineup

  • 20Anfrere
    just over1 minute

    making very slow progress, the slowest brand in this test

Medium hardness steel, pilot hole time

  • 1DeWalt
    3.29 seconds2nd
  • 2TEMO
    4.74 seconds
  • 3Klein Tools
    6.34 seconds

    (transcript renders this as '6.3 4', a caption-split decimal kept verbatim and treated as 6.34)

  • 41WANUE
    6.75 seconds
  • 5Sharptool
    around6.5 seconds
  • 6Hercules

    very close to 6 seconds, the fastest at that point in the test

  • 7Norseman
    just under6 seconds
  • 8PIT
    7.73 seconds
  • 9Toolant
    just over7 seconds

    trailing the Greenlee

  • 10OXMUL
    4.43 seconds3rd

    third fastest pilot hole in this test (per the closing recap for this segment)

  • 11KSEIBI
    2.26 seconds

    fastest pilot hole of this segment

  • 12Milwaukee

    not separately stated in the transcript

  • 13Greenlee
    over6 seconds
  • 14Snap-on Blue Point
    8.2 seconds

    the same speed as the Irwin

  • 15Irwin
    8.2 seconds
  • 16Neiko
    just over7 seconds
  • 17Diablo Freud Diablo
    just over9 seconds
  • 18Mac Tools
    11.77 seconds
  • 19EZARC
    11.87 seconds
  • 20Anfrere

    transcript 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 clear

Medium hardness steel, outcome

  • 1DeWalt

    drilled completely through to the 7/8 in hole in 7.79 seconds, the fastest full completion of the seven brands that finished this hole

  • 41WANUE

    could not quite finish the job, coming to a stop at 9/16 of an inch

  • 5Sharptool

    ran out of steam early at 0.68 in, did not complete the 7/8 in hole

  • 6Hercules

    came 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)

  • 7Norseman

    drilled completely through to the 7/8 in hole in 10.17 seconds, third place among the seven brands that completed this hole

  • 16Neiko

    drilled 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 seven

  • 17Diablo Freud Diablo

    drilled completely through to the 7/8 in hole in 17.29 seconds (transcript shows a stray '%' character after this number, treated as caption noise)

  • 18Mac Tools

    almost crossed the finish line but came up short at 0.82 in, just under the 7/8 in target

  • 19EZARC

    came to a stop at just over 1/2 in

  • 20Anfrere

    see above; final hole size not reliably determinable from the transcript

Stainless steel, outcome

  • 1DeWalt

    made the biggest hole at that point in the test at 0.64 in, though with some visible wear to the chisel

  • 2TEMO

    largest hole at that point in the test at 0.74 in, and the bit still looked as good as new afterward

  • 3Klein Tools

    left 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 in

  • 41WANUE
    0.59 in

    hole, looked nearly as good as new (nearly as good as the Teemo)

    0.625 in

    (5/8 in) hole, with a small amount of wear on the chisel point

  • 6Hercules
    0.56 in

    hole, still in pretty good condition

  • 7Norseman

    hole size just over approximately 0.5 in (transcript shows a garbled fraction rendered as 'a/2 in'), bit still in very good condition

  • 8PIT
    0.58 in

    hole, chisel point in the best shape of any brand yet

  • 9Toolant
    0.56 in

    hole, with some wear to the chisel

  • 10OXMUL
    0.54 in

    hole, still in very good condition

  • 11KSEIBI
    0.61 in

    hole, still in very good condition

  • 12Milwaukee

    made 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 flutes

  • 13Greenlee
    0.61 in

    hole, with quite a bit of wear and tear

  • 14Snap-on Blue Point
    0.44 in

    hole, smaller than average, with more wear and tear than most other brands

  • 15Irwin

    the stainless steel was too hard for the Irwin; chisel point left flat and damaged, no hole completed

  • 16Neiko

    performed reasonably well overall but the stainless steel proved too hard; chisel point left flat and dull, no meaningful hole completed

  • 17Diablo Freud Diablo

    the stainless steel proved way too much for the Diablo; narrator attributes this to a poorly shaped chisel point

  • 18Mac Tools

    struggled and was unable to drill a hole, with quite a bit of visible wear and tear

  • 19EZARC

    the stainless steel was way too hard for the EZARC; narrator says the chisel does not seem to have the right geometry for cutting efficiently

  • 20Anfrere

    unable 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' bit

AR500 armor plate outcome

  • 1DeWalt

    only 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

    the 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

    finished 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

    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

    stopped 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

    started 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

    described 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

    stopped making progress at around 12 seconds with quite a bit of wear and tear, reaching 7.4 mm depth

  • 9Toolant

    started 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

    short life at around 11 seconds, chisel described as pretty dull afterward, reaching only 6.86 mm depth

  • 11KSEIBI

    started 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

    quick to fail, at around 5 seconds, with significant damage; reached only 2.8 mm depth

  • 13Greenlee

    finished 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

    started 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

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
