Drillpro 50PCS 1/1.5/2/2.5/3mm HSS Titanium Coated Twist Drill Bits High Speed Steel Drill Bit Set
A part of the review has been auto-translated.
It's great to be able to buy these drill sizes we most often break and are too small to use in a sharpener, in a "bulk"pack. Awesome. They are just normal drills, nothing exceptional so 'quality' just gets 4/5 from me. I recall the story where the USA engineers around the time of WWII made the smallest drill in the world at that time. Story goes they sent a sample to the UK where their engineers drilled a hole down the centre of it and sent it back.
I tried them on aluminum, and they worked great. Nice thing about these bits is that they are HSS, so they can be used with Dremel, all you need is chuck adapter: http://bit.ly/2mDttBf
1.0mm and 1.5mm drills incorrect sharpening angle, does not cut after sharpening ok. Also, 2.0mm and 2.5mm few incorrect sharpening angle. Figures re-sharpened drill left, the right is an unsharpened
The drill bits are not sharp enough. I have ground one of them, but it is still not suitable for drilling steel. As described, it can be used for wood, plastic, aluminum. I hope for a PCB as well. (I haven't tested it yet.)
Lot of bits for good price. I tried them on aluminum, and they worked great. Nice thing about these bits is that they are HSS, so they can be used with Dremel, all you need is chuck adapter: http://bit.ly/2mDttBf
Very good product
I've checked 8x drills (at least one of each size). Out of this limited set - 3 drills were not sharp. Yet I was able to find a reasonably sharp one of the same size quickly. So obviously QA issue. As could be expected ...
50 pcs in total and that price perfect..
Product arrived perfectly as requested, only came missing a drill which is the smallest gauge, I don't know what number of it exactly, but it is the smallest of all,
I haven't tried it yet at this price and the good quality I am fully satisfied with this purchase. Thank you BANGGOOD for these opportunities. I haven't tried it yet but at this price and quality, I am satisfied with this purchase. Thank you BANGGOOD for these opportunities.
