Ideal micro drill bit for PCB board drilling, IT hardware engineers, repairing and maintenance staff, jewelry artists, wood working DIYers, hard metal part processors and other hand work professionalsUser Instructions: To effectively use cobalt drill bits on hard metals, keep speeds low, use a metal cutting paste or fluid for lubrication, apply firm but steady pressure, and back out the bit frequently to clear chips and cool the bit. Always secure your workpiece and consider using a pilot hole for thicker materials to prevent bit walk and reduce stress.Essential Tips for Drilling AluminumAluminum is a soft metal, but don’t think it is easy to drill through. It melts at just 660°C, and the chips can fuse onto your bit if it gets too hot — especially when drilling thicker sections. Cobalt drill bits with at least 5% cobalt can dissipate heat faster, reduce chip welding and improve hole quality. They’re more resistant to wear. Drilling aluminum can be smooth and hassle-free — if you use the correct drill bit and technique. But ignore the essential tips, and you could end up with melted metal, gummed-up drill bits, or damaged workpieces.1. Start from Low Drilling Speed: Too much speed = too much heat. And heat is your enemy and is detrimental when drilling aluminum. Start from very low speed depending on your drill bit size, material thickness and hardness.2. Always Use a Cutting Lubricant: Apply a cutting paste or fluid to reduce friction and prevent aluminum from sticking to the bit.3. Apply Light, Consistent Pressure: Let the drill bit do the work by avoiding excessive pressure, which can lead to clogging. Avoid leaning into the drill.4. Clear Chips Regularly: Pull the drill out of the hole frequently to clear away aluminum chips and prevent the bit from jamming.5. Safety First: Always wear safety goggles and secure your workpiece with a clamp.

Review: Good, maybe a little short - These appear to be metric drill bits, and are just similar to the English sizes. Even the 1 mm size held up to drilling into redwood, with being careful with the drill. The bits weren't as long as the ones I was replacing, but for the price I say 5 stars.
Review: The first drill bit just snapped. Others would not drill in to steel plate. Do not buy. - Totally worthless.

### ⭐⭐⭐⭐⭐ Good, maybe a little short

These appear to be metric drill bits, and are just similar to the English sizes. Even the 1 mm size held up to drilling into redwood, with being careful with the drill. The bits weren't as long as the ones I was replacing, but for the price I say 5 stars.

### ⭐⭐⭐⭐⭐ The first drill bit just snapped. Others would not drill in to steel plate. Do not buy.
*by A***R on 30 May 2022*

Totally worthless.

### ⭐⭐⭐⭐ They are pretty standard drill bits, nothing fancy
*by J***G on 1 April 2025*

Decent for the price. They drilled holes. Not the best, but look at that price The smallest one, which was the one I really needed, does not fit in the chuck on my Milwaukee cordless drill. It's too small. Not really anything you can do about it, but I'm leaving this for other people.
