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)
- 1DeWalt6.55 seconds2nd
second place behind the CB/KSEIBI; four years ago this same brand cut through mild steel in around 8 seconds
- 2TEMO7.53 seconds3rd
third place; four years ago this same brand made the pilot hole in 11 seconds
- 3Klein Toolsjust over12 seconds
four years ago this same brand was one of the slowest in the lineup at 34 seconds
- 41WANUE12.23 seconds
described as making pretty slow progress compared to CB, DeWalt, and Teemo
- 5Sharptooljust over11 seconds
took the lead at that point in the video
- 6Hercules8.57 seconds
took the lead at that point; four years ago this same brand needed 17 seconds
- 7Norseman10.17 seconds
- 8PIT
very close to 13 seconds, second place behind the Sharptool
- 9Toolant12.34 seconds
described as not making very fast progress compared to many less expensive brands
- 10OXMULjust over8 seconds
took the lead at that point
- 11KSEIBI4.17 seconds
about twice as fast as the OXMUL, very impressive, new fastest time at that point
- 12Milwaukeejust over30 seconds
four years ago this same brand was pretty fast at just 10 seconds, a significant slowdown this time
- 13Greenlee8.41 seconds
a little faster than average
- 14Snap-on Blue Point15.48 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
- 16Neikojust over14 seconds
four years ago this same brand was one of the slowest at over a minute
- 17Diablo Freud Diablojust over30 seconds
four years ago this same brand drilled the pilot hole in 18 seconds, a significant slowdown this time
- 18Mac Tools24 seconds
one of the slowest in the lineup
- 19EZARC25.82 seconds
one of the slowest in the lineup
- 20Anfrerejust over1 minute
making very slow progress, the slowest brand in this test
Medium hardness steel, pilot hole time
- 1DeWalt3.29 seconds2nd
- 2TEMO4.74 seconds
- 3Klein Tools6.34 seconds
(transcript renders this as '6.3 4', a caption-split decimal kept verbatim and treated as 6.34)
- 41WANUE6.75 seconds
- 5Sharptoolaround6.5 seconds
- 6Hercules
very close to 6 seconds, the fastest at that point in the test
- 7Norsemanjust under6 seconds
- 8PIT7.73 seconds
- 9Toolantjust over7 seconds
trailing the Greenlee
- 10OXMUL4.43 seconds3rd
third fastest pilot hole in this test (per the closing recap for this segment)
- 11KSEIBI2.26 seconds
fastest pilot hole of this segment
- 12Milwaukee
not separately stated in the transcript
- 13Greenleeover6 seconds
- 14Snap-on Blue Point8.2 seconds
the same speed as the Irwin
- 15Irwin8.2 seconds
- 16Neikojust over7 seconds
- 17Diablo Freud Diablojust over9 seconds
- 18Mac Tools11.77 seconds
- 19EZARC11.87 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
- 2TEMO

- 7Norseman
drilled completely through to the 7/8 in hole in 10.17 seconds, third place among the seven brands that completed this hole
- 8PIT
came to a stop at approximately 0.5 in (transcript shows a garbled fraction rendered as 'a/ in')
- 9Toolant
also trailed the Greenlee here, coming to a stop at 0.68 in
- 10OXMUL
outperformed the Hercules, coming to a stop at just over approximately 0.5 in (transcript shows a garbled fraction rendered as 'a/2 in')
- 11KSEIBI
the spiral flute design pulled the bit into the cut too fast and it ran out of steam at 0.44 in

came very close to finishing, stopping at 0.81 in (just short of the 7/8 in / 0.875 in target)
- 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
- 41WANUE0.59 in
hole, looked nearly as good as new (nearly as good as the Teemo)
- 5Sharptool0.625 in
(5/8 in) hole, with a small amount of wear on the chisel point
- 6Hercules0.56 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
- 8PIT0.58 in
hole, chisel point in the best shape of any brand yet
- 9Toolant0.56 in
hole, with some wear to the chisel
- 10OXMUL0.54 in
hole, still in very good condition
- 11KSEIBI0.61 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
- 13Greenlee0.61 in
hole, with quite a bit of wear and tear
- 14Snap-on Blue Point0.44 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
