	Klein Tools	$55.00	$6.88	Search on Amazon	China
The overall winner at 2.7, and it wins by having no weakness. Threads holding 84 in-lb are second best in the review, tapping at 11 in-lb is joint third lightest, mild steel took 6.75 seconds with the bit undamaged, and aluminum drilling at 4.55 seconds is respectable. It is expensive at $55, but the eight-piece set is more comprehensive than the Milwaukee's five.
	Milwaukee	$40.00	$8.00	Search on Amazon	China
Second overall at 3.3. Five bits for $40, rated for impact drivers, and strong in the two tests that matter most: threads holding 82.67 in-lb and a mild steel pass in 6.75 seconds with the bit still looking new. Tapping is light at 15 in-lb. It is only average in aluminum at 4.41 seconds, and $8 a bit is the second highest price here.
	Junreox	$7.00	$1.17	Search on Amazon	China
Six bits for $7, the cheapest set here at $1.17 a bit, and it is genuinely usable. It drilled aluminum in 4.87 seconds, cut threads at a moderate 23 in-lb, and made threads that held 72 in-lb — better than the $53 IVY Classic and the $27 NEIKO. It also survived the mild steel test in 12.3 seconds, though with visible wear on the flutes afterwards.
	VALKYNOS	$16.00	$1.23	Search on Amazon	China
A 13-piece set with a quick-change adapter covering M3 to M10 and SAE sizes to 1/4 inch. In aluminum it was slow at 6.78 seconds and got slower with each hole, but the threads it cut were solid at 74.67 in-lb. It is too brittle for steel: it snapped partway through the 1/8-inch mild steel test.
	OCR	$18.00	$1.38	Search on Amazon	China
The worst set in the review by a wide margin. Its three aluminum holes took 17.8, 29.4 and 53 seconds as the bit progressively destroyed itself, tapping took 39 then 46 in-lb, and the threads it produced were not usable enough to test for strength. It then seized in mild steel and broke on the way back out.
	GMTOOLS	$19.00	$1.46	Search on Amazon	China
Drills quickly in aluminum at 5.34 seconds and cuts respectable threads at 76.33 in-lb. The tap is the problem: it needed 51.67 in-lb to cut threads, by far the highest in the review and roughly five times the Hercules. That resistance caught up with it in mild steel, where it stalled before finishing and came out with its flutes in very poor condition.
	AUTOTOOLHOME	$20.00	$1.54	Search on Amazon	China
The fastest of the budget sets in aluminum at 4.46 seconds, tied with the NEIKO, and its threads were the third strongest in the whole test at 82.33 in-lb — ahead of the $55 Klein Tools on that measure alone. But it takes 28.33 in-lb to tap, and it seized in mild steel. It came out intact, which the GMTOOLS did not.
	Hercules	$20.00	$3.33	Search on Amazon	China
The Harbor Freight set, and the sharpest tap of any true combination bit here: 10.67 in-lb to cut threads, second only to the HighFire's separate tap. It drilled aluminum in 5.31 seconds and finished mild steel cleanly in 11.9 seconds with the flutes still in good shape. The catch is thread quality — 64.67 in-lb is among the weakest in the group.
	THINKWORK	$24.00	$1.85	Search on Amazon	China
Titanium-coated high-speed steel that lands in the middle of nearly every chart: 5.99 seconds in aluminum, 17.33 in-lb to tap, 68 in-lb of thread strength. It did complete the mild steel test in 13.67 seconds with its flutes intact, which puts it ahead of six sets that failed entirely.
	DeWalt	$27.00	$5.40	Search on Amazon	China
A five-piece impact-rated set with a speed tip. It is quick and easy on the tool everywhere — 4.77 seconds in aluminum, 14.67 in-lb to tap, and 9.9 seconds through mild steel with the bit still looking new afterwards. Thread strength at 71.67 in-lb is only average, and at $5.40 a bit it costs more than twice the NEIKO for similar results.
	NEIKO	$27.00	$2.08	Search on Amazon	China
The value pick. Thirteen pieces in both SAE and metric for $27, tied for the fastest budget set in aluminum at 4.46 seconds, a light 14.33 in-lb to tap, and 9.65 seconds through mild steel — faster than the DeWalt and beaten only by three sets costing twice as much. It came out of the steel in good condition. Thread strength at 67 in-lb is its one weak number.
	DKIBBITH	$30.00	$2.31	Search on Amazon	China
Black oxide high-speed steel, a little slower than average in aluminum at 5.8 seconds and heavy on the tap at 29.67 in-lb. It redeems itself where it counts: threads holding 74.67 in-lb and a completed mild steel pass in 11.25 seconds, with more wear than the DeWalt or NEIKO but no failure.
	HighFire	$30.00	$	Search on Amazon	China
Not a combination bit at all — five separate drills and five separate taps, which is why its drill is the second fastest here at 3.18 seconds and its tap the lightest at 9.33 in-lb. The threads are the weakest in the review at 49.67 in-lb, and once you add the time to swap bits, its mild steel pass takes about 15 seconds against the Klein's 6.75.
	HIDOTOL	$33.00	$2.54	Search on Amazon	China
The fastest drill in the entire review at 2.99 seconds in aluminum, and almost nothing else works. Tapping takes 31.33 in-lb, the threads it produces hold only 55.67 in-lb, second weakest here, and it seized in mild steel after drilling the hole quickly. A fast drill attached to a poor tap.
	IVY Classic	$53.00	$6.63	Search on Amazon	China
M2 high-speed steel, and the fastest set through mild steel in the review at 5.62 seconds — more than a full second clear of the Milwaukee and Klein — while coming out in good condition. It is quick in aluminum at 3.37 seconds and light on the tap at 11 in-lb. What it does not do is cut strong threads: 68 in-lb is below average.
	Greenlee	$62.00	$10.33	Search on Amazon	China
Cuts the strongest threads in the review at 90 in-lb, six above the Klein Tools, and drills aluminum quickly at 4.48 seconds. The problem is steel: it seized in the 1/8-inch mild steel test and had to be finished with an impact driver. At $10.33 a bit it is also the most expensive set here.
	IDEAL	$70.00	$8.75	Search on Amazon	Taiwan
The only set not made in China, using an unusual three-flute drill design. That design is slow in aluminum — 9.45 seconds, second worst here — but it makes the third strongest threads in the review at 83 in-lb and it completed mild steel in 9.49 seconds looking untouched. It is the most expensive set at $70.
