Cutting Wheel Set Compatible with Plastic 44pcs for Rotary Tool, HSS Circular Saw Blades 6pcs, Resin Cutting Discs 20pcs, 545 Diamond Cutting Wheels 10psc with 2 Screwdrivers

I only bought this for the resin cutting discs (the black ones). I used it to cut through rusted exhaust fasteners where an angle grinder would be too big/unwieldy.I used this kit with Harbor Freight's "1.3 Amp Variable Speed Rotary Tool Kit".To get an idea of what I had to cut through, I cut the following:1. Cut straight through steel M10 exhaust studs to lop them off completely. I had to do two of these.2. Cut a few sides off of steel M10 nuts so I could remove the nuts from the studs. This is for when the nut is so deformed and dissolved due to rust, that neither a regular nor extractor socket could be used. Just cut off a side or two, the nut's clamping power will be relieved then the remnants of the nut can be popped off the threads sideways/perpendicular to bolt's length, with a hammer and chisel. I had to do this with three nuts and these discs.3. Cut straight through flat 1/2" wide stainless steel exhaust clamps holding heat shields on, the nuts and bolts holding the heat shields on were too far gone to get any type of socket on, had to do about six of these.I used a single resin disc to cut through all of those. For the price I was expecting rotten quality: discs exploding on me, wearing down really fast, flying off mandrels, etc. Instead I only needed to use one disc for all of it, the mandrel didn't fail or loosen, by the time I was finished the disc was barely worn and still usable. The performance for the price was great and a nice surprise. I intend to continue using it until that disc fails which is probably not going to be any time soon. Having the ability to cut through metal with such small discs is very handy. Cutting straight through an M10 exhaust stud took about one minute, without applying any pressure either just let the speed do the work, make sure you wear safety squints, gloves and block the sparks if necessary, may want to wear a mask with a particulate filter too, otherwise you can taste the dust lol.Everything in the kit comes in a handy vinyl pouch with see through plastic pockets to organize the contents. I put the resin discs in a separate zip bag with a silica gel packet to keep it free of moisture and avoid water or atmospheric humidity from degrading the resin over time, though they're so small that even if they did come apart mid-cut I doubt they'd do any damage, at least unlike a 4-5 inch angle grinder wheel coming apart at 11000rpm LOL...

For the price this set is great! Did the job I needed it to do. Cutting blades get dull fairly quickly but I was able to cut vinyl flooring planks to the custom shape I needed with only two blades. I recommend this product.

This works great for all kinds of DIY projects at home. I have used it a numerous times and it has saved me time and money. I have cut wood, light steel, bolts, plastic with the kit with no problems. It takes a little longer than using a sawzall but I can also get into tight places. It also works great when repairing Xboxes and other electrical components that are not designed to be taken apart to be repaired. I will buy again.

Very dangerous in some circumstances! Don't run at high rpms. Use bigger, heavier, hardened steel, not brass, mandrels. The saw blades have very high risk, use gently. Cheap mandrels like the ones included bend & fly off if pressed or even if not sometimes. Consider making a larger hole for a thicker mandrel. Wear eye, face, etc. protection. Very useful however.

Great product, so far cutting with easea

Works okay. Not the best quality

These blades are an amazing value! The assortment and the quantity is very generous for the price. I like the fact that you have 3 different types of cutting blades and the saw tooth blades come in different sizes. This is a wonderful set and perfect for hobby or even professional applications.

Damn good value, if you were to buy this at a hardware store, you’d pay 3-5 times as much.
