Tacklife-Hole Saw Kit, 17 Pieces 3/4’’-5’’ Full Set in Case with Mandrels, Hex Key and Install Plate for Wood, PVC Board,Drywall and Plastic Plate Drilling, Hardened High Carbon Steel -PHS03C

Great for the price. Haven't used all the sizes, but I have used a few of them so far. Bought this mainly for PC modification - they are great for cutting fan holes because the sizes are all very close to the standard fan sizes (60/80/90/120/140mm). I have used them to make cable routing/ventilation holes in my desk, TV/media unit and also to make a clothes rail support.

Compact and ever so handy. Lost count of how many times I have used this kit. For me as a Biker it's a "must have" item. Quality is fantastic and the robust sockets and drive bits should last a lifetime. Can't believe how many varieties of scew bits it contains. Great stuff!
