I loved these bits. They are delicate but cut brass orifices very nicely. Great product. BTW, the shafts were ideally suited to fit my Dremel drill

Used on a 1mm think aluminum plate, all of them shattered under very light pressure, not recommended

Building a watch and needed to drill holes for the dials feet. This worked VERY good just off a dremel and steady hands.

Decent quality bits, though can be easily breakable if you're not using it straight up and down. I use them to drill shells and to enlarge holes in gemstones and pearls. They get the job done, but it's good to have the extras as they will dull after several uses or will break if you use too much pressure or lean them one way or the other while drilling.

I was using these to drill through very thin plastic and they all broke during the first few minutes of use. Only 4 pictured here cus the other one got thrown into oblivion. Really disappointed this is probably the worst purchase I've ever made on Amazon.
