Hole Saw Kit, 17 Piece General Purpose 3/4 to 2-1/2 Set with Mandrels, Bi-Metal, Durable High Speed Steel (HSS). Fast Cut Clean, Smooth and Precise Holes Through PVC, Metal, Wood, Plastic, Drywall

I bought these because I thought there were Kobalt.

Bummer, 30 days after purchase. The teeth on the saw, just disintegrated .

My dad loves this

Good deal fir the money. However, extremely difficult to take apart once you have drilled your hole. I use two pipe wrenches to separate the cutting bit from the drill bit.

Using it on thin aluminum and these cut horrible. Bit constantly falls out despite realigning and tightening. Save your money and buy a Lennox kit.

As expected

Worked well on thin metal such as sheet metal of furnaces & other HVAC equipment

not very sharp cutters. ⅜ shank not as sturdy as other brands with 7/16 shank. once the cutter is screwed onto the shank and used once, the cutter is practically impossible to unscrew from the shank and change. overall a sub-par tool that im very disappointed to have bought. will buy the other brand, and just accept my loss.

I bought this kit because i am sick of digging around looking for parts and pieces of hole drills i already have. This kit comes with a quality plastic case , two center augars with a wide range of hole drill sizes. I only used it once but the bit held up fine. Id definitely recommend this product for several reasons. 1st the case and latches are well made. Will last a long time. 2nd the bits are of above average quality for this price range or double this price. 3rd for the average homeowner or contractor that needs a decent kit but doesnt want to break the back, its perfect

I used only the 2.5 saw and the treads stripped out after 5 holes through 3/4 plywood at a slow speed. Had to weld the arbor to the saw to finish drilling the holes I needed
