|This jobber length drill bit set includes high speed steel (HSS) drill bits in sizes 1-60. The set comes complete with a steel storage box. Ideal as a pre-drill for tapping of holes and for many other aircraft building applications.|
Havent had a chance to use the bits but when package arrived the metal bit holder was bent and the rivet hinge was broken.. very thin holder cheaply made. I hope the bits are better quality
The the drill bits are OK if you use them very, very carefully (I think they are over-hardened, or not temper -relaxed) and will break easily. The holding box is a joke, it arrived fallen apart and 10 - 12 pieces of very tiny drill bits were all over the larger shipping box, some broken apart. After 5 times opening the box it doesnt close anymore. The lowest quality tool I ever bought. Not worth 10 bucks.
These are very low quality.
Very brittle bits, easily broken. I had one crumble into 4 pieces just drilling out a couple -4 rivets!!!
