Micro Drill Bit for PCB, Acrylic, Plastics
Tungsten Carbide Tip
Made from ultra-fine grain carbide material for precise and easy experience, high hardness, good toughness, wear resistance, high strength, resistance to bending.
Spiral Flute Bits
Sharp cutting edge provides smooth cutting, reduces cutting force, prevents drill broken, and improves the drilling accuracy. Spiral chip space design for fast and clean chip removal.
High Precision
With sharp cutting edge, milling groove and clean surface. PCB drill bits have good milling and cutting performance. Can work quickly and cleanly, no glitches or scrap left.
Features
- Can ensure high work efficiency.
- Carbide can run at higher speed than high-speed steel.
- High speed steel shank provide high hardness and good toughness for wear resistance.
Wide Applications
Suitable for drilling and engraving PCB, acrylic, plastics, fiberglass, wood, aluminium, soft metals. Used on PCB drilling machines, engraving machine, CNC lathes, machining center.
Carbide PCB Drill Bits replace your CNC machines and any hand held tool. Large drill bit chip space, chip resistance, chip smooth, small drilling heat.

I had to drill out a 6-32 screw to extract. Broke 2 bits before I realized I need high speed to keep the bit from grabbing. Managed to get a 1.6mm hole in the screw to extract with a micro extractor. Overall pleased and happy with the price.

Love the case these bits came in. I use them as pearl reamer. Its the perfect thickness for what I need. The bits are great quality. I ordered this set since the last drill bit I had fell and broke. Been using one of these for over a month now and it has not broken yet. Having the extra is a security for me since I use them all the time. Definitely reccomend.

Inexpensive bits 0.8mm which although useable are very fragile. They appear to be more useful for light engraving like printed circuit board etching than any kind of "milling".Feed speeds need to be kept below 200mm/ min.On PCBs, 0.6 mm are only useful for drilling

First, I ordered blue and got orange, but that doesn't really matter to me...I bought these for drilling holes in nickel/iron meteorites, but 2 broke after drilling one hole, and 2 broke during the drilling of the hole, and lodged inside... that means that I can't get them out, since they are just as hard as a fresh bit... not happy with them.

I use these bits to cut thin lines in cigar boxes to fit the neck during the build. They cut extremely well as long as you don't overheat the bit and cut the line slower than faster. I purchase this item regularly and would recommend them if you are cutting wood or plastic, drill small holes and don't mind the tendency to be a touch brittle to side forces. I recommend this bits and will purchase again

Very delicate. I broke through two of them in the first 5 minutes of using them (gently) to drill several holes in a PCB. Third one I used in the pack held up better but I probably won’t buy this brand again.

Got these to cut the fret slots for a few mountain dulcimers I'm attempting to build. Was worried that they would be too fragile, so I took it easy. Cutting in Walnut. First one I used 24000rpm, .01DOC and 20IPM feed rate. No problems. Sped it up to .015DOC, 30IPM and still worked great. Only negative is that the cut isn't as smooth as I'd like, but a little sandpaper takes care of that. I will experiment with faster speeds and deeper cuts now that I know what works.

These seem very good quality. I did break 3, but I'm using them in a regular drill, to drill safety wire holes in hardened fasteners on my race bike. I had 2 pipe plugs in particular that even a colbalt drill bit wouldn't touch and these went right threw like it was nothing. When they broke threw is when they broke as they are tiny bits, and I tweeked the drill, but were easy to remove, and were my fault since, again, I'm using a hand drill with a tiny fragile bit. The 1.6mm bits are also perfect size for safety wire.

So far I’m happy with these bits. I use them to open up the pilot jets on a gx200 clone engine. Perfect size to cure the no-load hunting issue on this engine.

Not thrilled with these. Fragile, even on the lowest speed in my rotary tool. Did not seem to be completely straight. Broke 5 in rapid succession. Will not buy again
