CLEVELANDC01330 CLE-MAX 115 Piece High-Speed Steel General Purpose Jobber Length Drill Bit Set, Uncoated (Bright) Finish, Spiral Flute, 118 Degrees Point, 1/16" to 1/2", A to Z, #1 to #60 Size

Won't say they are the "Best" but they are very good bit's.Looked around and found these at other places for up to $700.The next step up would have been the "Norsman" at $1,000 or morefor a 115pc set. The Amazon price of these is a good one at less thanhalf of most retailers.I bought the bright for sharpen ability... this way there there isn't a chanceof hardening or tempering of a case depth or coating used for hardening.I bench grind to sharpen using a "drill point gauge" and plenty of coolant tokeep the bit cool .

look this is a set of drills,they are used for drilling holes for various applications,having said that this is a set of Cleveland drills . this is good high speed drill bits,not Chinese junk.
