Customers say

Customers find the hole saw kit to be of good quality and worth the $70 price tag, with one customer noting it outlasts conventional ones. The tool cuts through stainless steel counter tops smoothly, and customers appreciate its speed and ease of use, with one mentioning it makes panel tubs easy to work with. However, durability is a concern as customers report the carbide teeth breaking and the kit breaking after drilling one hole.

    I wish I had bought these long before I did.
    This is a very nice product for anyone that does electrical work. It has the sizes you will need for most clamp connectors and conduit. Cuts through the metal box very smoothly with no sharp edges.

    Very handy
    This type of product works very nice and with the spring pushing the slug out after nice.Just can not use on any angle, must be straight on. I broke two of the bits and had to buy replacements. It does come with a spare. Very nice set and cuts well for electrical boxes/panels.So main limitation is must be straight into your surface, which may not always happen.

    Perfect design, decent build.
    Good hole saw set. The case seems very durable and it nicely organizes all three sizes of hole saw with an additional slot for a spare pilot bit.As for the hole saws themselves, they’re brilliantly designed. I love, love, love the ejection spring built into the pilot bit. It lets me go straight from drilling one hole to the next without missing a beat. These also have a stopper, or flange, built in to prevent accidental over drilling. It seems Klein thought of everything when they designed this.The only real problem I’ve had so far is that I thought the 1-1/8” hole saw (3/4” trade size) died prematurely. The carbide teeth were breaking after only moderate use, and I do try to be as gentle as possible to preserve tool life. I picked up a replacement from the Home Depot, and it’s been going fine so far. If you’re someone who works with a 12V drill handy, that will most likely solve this issue.The convenience of this set up is hard to beat. I also have Klein’s knock out ratchet set, which I think is more durable and lets me do better work. Still, for this quality at less than 1/3rd of the price, you can’t go wrong.

    Set comes with 3 hole saws and one spare bit that pilots in the centre. I broke one bit the first time I used the hole saws on some mild steel, 4mm thick. Then I’ve used all three of them maybe 2/3 times since. In that time, the middle one has shattered or chipped every single one of its cutting edges, you’d think these were made of glass.

    Buy 7/32 drill rod and make your own pilot bits!1-7/8 long. This will prevent the pilot from walking inside the hole and snapping off. You should be drilling your holes out first and starting your carbides flush to the metal with cutting oil in LOW SPEED. When used properly by a tradesman these carbides are excellent. Its not the bad product its the BAD TRADESMAN!

    Have used for stainless steel – 14 and 16 gauge only. Broke one carbide tip off on the fourth hole, had a new one put on and tool sharpened and it has cut about 30 more holes and looks like it could cut another 30. I think the carbide cutter that broke was a poor weld.
