Chicago Latrobe - 57715 150D Series High-Speed Steel Jobber Length Drill Bit Set with Metal Case, Uncoated (Bright) Finish, 118 Degree Conventional Point, Wire Size, 20-piece, #80 - #61

Bits seem to be of good quality, but case is a little “ iffy” - has trouble holding bits securely

The scale of the picture is very deceptive. The metal bit case is less than 1.5 inches wide. These are very small bits. Sizes seem correct. The bits are a little loose in the holders. One fell out into the packaging during shipping. Be careful with them as the size is easily damaged. Keep the carefully sorted or you will need to use a micrometer to get them back in order.These bits are designed to be used with a very small pin vise.

i bought these small very skinny drill bits for my picture frames, for pilot holes, to put hardware on them and then hang them with wire, much easier to level a wire picture hung by a wire, than have a hole in it for the nail or screw, that may or may not have the picture with frame balanced with pre-drilled holes in the frame, # 2, this is the best part ! , only having one hole in the wall, centered , squared, if thought out well, with the one hole method, pictures can be changed out by season !, i learned how to do this type of work from my wife, not from the ask, but from perception, for what she ask, these bits can also be used for port hole cleaning in carburators! Use Caution when doing so!!!
