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 Flutes
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.

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

Very sharp--make very clean holes in 1/4" pine. Using a Moto Tool drill press and have no breakage--over 200 holes so far.

These things are so brittle that they snap even with a jewelers drill press. Very sharp, but break with the smallest pressure.

I use these bits in the 1.0mm size to open up predrilled holes on freshwater pearls. I've tried many different bits with a micro rotary tool, and most took a long time to drill, heating up the pearl and causing internal scorching. These bits are much sharper and drill 10x faster, and hold on much tighter. My only complaint is that some seem to be created with more fragility. I've had 2 break mid shaft in a row after 1 or 2 uses only to have a 3rd last well over 20 drills before snapping. But the ability to drill cleanly, quickly, and precisely is why I will keep buying these, despite the problem with breaking.

These work great with a high speed drill. I use a Proxxon bench drill running at 8500 rpm, works fine for drilling pcb boards.You will not be able to use this product successfully at low speeds, and with a hand held drill you will probably snap the drill bit when you have drilled a hole and are extracting the bit out of the hole. Been there, done that.

Great quality. Use on copper laminated fiberglass printed circuit boards. No issues. Makes the drilling job quick.

I broke 10 of these bits in 20 minutes trying to drill through a piece of abs plastic. They are junk.

Arrived quickly. Used to drill holes in a fairly small pc board, 4" by 3". Not that many holes. I mounted the bits in a drill stand and used 2 bits to drill all the holes. The first bit broke half way thru the process. This could have ben my fault.. The bit seemed to be still sharp at the end of the job.

FIRST DAY....LOVED THESE FOR CAR MODELING but I BROKE 4 IN ONE DAY yOU SIMPLY CAN NOT PUT PRESSURE ON THEM iF YOU ARE DRILLING AND MEET A TOUGH SPOT...STOP..BACK U AND TRY AGAIN WITH VERY LIGHT PRESSURE ( LET THE DRIL TRY TO SLOWLY CUT THROUGH ...i'M ORDERING MORE LOL

I put one of the flex shaft and by the time i came back to use it, the tip was broken. I wasn’t expecting vibranium level strength but I expected tungsten carbide to be strong. The drill well but break if you breath too hard 😠I want my money back
