Platinumedge Metric Twist Drill Bits Set

The Verdict

Let’s cut the chase: if you’re shopping for metric drill bits, you already know most sets under $30 are junk. The Platinumedge set sits in that awkward middle zone — cheap enough to tempt you, priced like it might be decent. Here’s the real deal after testing and combing through buyer feedback.

What you actually get
A 25-piece set covering 1.0mm to 13mm in 0.5mm steps. That’s the full metric spectrum you’ll need for most automotive, woodworking, and light metal projects. Each bit is HSS M2 steel with a 135° split point — the split point matters more than the brand name, because it prevents the bit from skating across the surface when you start drilling. No pilot hole required on most materials.

Performance in the real world
I ran these through mild steel (1/8" plate), aluminum, and hardwood. The 135° tip does exactly what it claims: clean entry, no walking, even on rounded surfaces like a door hinge. The M2 steel holds its edge far better than the “HSS” stamped bits you find at big-box stores that dull after ten holes. On steel, I drilled about forty 6mm holes before noticing any slowdown — respectable for the price point.

One thing that surprised me: the shanks are precision-ground, not rolled. That means less runout in the chuck, which translates to straighter holes and less wear on the bit. You can feel the difference when drilling deeper holes — no wobble, no fighting the drill.

What buyers consistently praise
Scrolling through the 220 ratings, the pattern is clear. One verified buyer wrote: “Finally found a metric set that doesn’t bend on the first use. Drilled through stainless steel brackets without breaking a sweat.” Another noted: “The size range is perfect for motorcycle work — I’ve used half of them already and none have chipped.” The 0.5mm increments get repeated shout-outs because most sets skip them, forcing you to buy singles.

Where it falls short
No case. Zero. Zilch. The bits arrive in a thin plastic sleeve with a cardboard insert — fine for a drawer, useless for a workshop. You’ll need to buy a roll or case separately, which adds to the real cost.

The sub-3mm bits are the weak link. One user reported: “The 2.5mm bit snapped on a steel beam at moderate pressure. Wasn’t abusing it, just normal drilling.” That’s not unusual for small HSS bits — they’re inherently fragile — but it’s worth knowing before you rely on the tiny sizes for heavy work.

Also, the laser-etched size markings on the bits themselves wear off after a few uses. The shanks are unmarked, so you’ll be squinting at the sleeve to identify sizes. Minor, but annoying when you’re mid-project.

Who should buy this

• Home DIYers who need metric sizes for furniture, appliances, or hobbyist metalwork — this covers 90% of what you’ll encounter.
• Motorcycle or bicycle mechanics — the 0.5mm steps are ideal for fasteners and precise pilot holes.
• Anyone tired of buying single metric bits at $4-6 each. At this set’s price, you’re paying roughly a dollar per bit, and they outperform the cheap singles.

Skip it if you’re a professional fabricator doing daily heavy steel work — you’ll want cobalt or carbide sets that cost four times as much. Also skip if you need a storage solution, because you’ll have to buy one anyway.

FAQ
Q: Are these bits compatible with a standard 3/8" chuck?
A: Yes. The shanks are round and fit any standard chuck. The 13mm bit has a 13mm shank, which is the max a 1/2" chuck accepts — most drills handle it fine.

Q: Can I use these on stainless steel?
A: In a pinch, yes, with cutting fluid and slow speed. But they’re not designed for heavy stainless work. Stick to mild steel and aluminum for best results.

Q: Do they come with a case or organizer?
A: No. Just a plastic sleeve. Budget for a drill bit index case if you care about organization.

The Verdict
Buy it if you want a complete metric range that actually cuts straight and holds an edge, without spending premium prices. Skip it if you need a rugged case or plan to hammer on the small sizes. For a home workshop, this is the best value in metric bits under $30 — just add your own storage.

Rating: 4.2/5 — Solid performance, honest pricing, and one significant packaging flaw that keeps it from a perfect score.
