50pcs PCB Drill Bits Set Spiral Flute Carbide 0.3mm-1.2mm for Print Circuit Board Stone Dremel Jewelry CNC Engraving (5pcs each)

Great mini drill bits. Super sharp and strong work great in a slower variable speed Dremel tool.

I show you in my video just hiw sharp and how sturdy these things are. They go directly through steel, Plastic of different densities, and even rock. Absolutely the best and sharpest Dremel tool out there. I don't even need the Dremel I just use it with my hand because they are SO SHARP I seriously do nit need the extra power. If you have a series of holes to make a dremel would be the way to go so it's not so time consuming but im telling you these are the best out there... my video shows it all. I show me making new holes in my cigarette filters that are ass and don't have enough or big enough holes to get more then one cigarette out of them. I also show a bottle cap to gove you and idea on the variety of density they drill into.I also show me putting a new hole in my steel cigarette filter. All by hand. Absolutely no problem and takes literally seconds. By hand. Just watch the video ☺️

Fab product, works with my Dremel and coupled with the Dremel workstation makes drilling PCB and PC screw holes a breeze. Love it, love it, love it. Thanks

腕時計の金属ベルトを加工する為に購入しました。穴径を多きする為に使いましたが、案の定１本目は途中で折ってしまいました。 こんな時も５セット有るので、安心して作業を終えることが出来ました。今回は一番太いドリルを使いましたので、他のサイズは分かりませんが良い商品です。

I was trying to find a jeweler who could drill new lug holes for my watch because I was changing to a different style of band made by the same company that made the watch but the lug hole locations were different. After hours of research and YouTube searching, I decided to try it myself. I used one of these bits to drill into a stainless steel watch case with a dremel and it worked exactly as I needed it to. I bought this set in case I broke the but trying to drill and I only had to use one bit. You have to go slow and keep the same angle when drilling otherwise you will break them. This worked like a dream and the fact you’re getting 50 bits all together for this price makes it well worth it. At least it was for me.
