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

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

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

As expected

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

These were so badly made ,they wouldnt cut. Most were not even close to round, and welds werent lined up. Unuseable, waste of time and money. Avoid these.

Nice little set

The material is weak. I made 3 holes on metals studs and the teeth are gone. I couldn’t remove the bit out of it.

Hood to have . Not heavy duty

Pretty good
