I enjoy working with miniature arts and crafts a lot. My drill bits sometimes break, but so far I've had good luck with the Hymnorq Small 50 twist drill bit set. I like that they come in multiples of each size because I break up small pieces. They come well packaged and have so far held up to multiple projects drilling holes in wood, hardened clay and shells. I would recommend this set to anyone who wants to drill very small diameter holes. Thank you for reading about my experience. I hope this was helpful to you and please click the button below.
