> 3 dayUsed it to cut a 3” hole in a 550 gallon stainless steel tank. It cut through it faster than my drill could handle. I will be buying more of these. Just wish they were made in USA

> 3 dayTCT holesaws can be damaged by impact. The box protects the carbide tips nicely. While I would have preferred a different size selection, this set is a good compromise for the money. The only thing I would like to be different is the shank. If the lower portion were a Weldon shank, it would fit in a magnetic drill chuck, enhancing usability.

> 3 dayMade one hole through 5/4” decking spring came off and blade became extremely dull! If not for wood my mistake but it’s definitely a fight for the second hole!

> 3 dayCut fine but a weak shank that breaks almost immediately when you start to drill. Might be ok in plastic with a very weak drill motor.

> 3 dayYou get what you pay for with this. It has carbide teeth but expect several to break off if you have more than one hole to drill. 4 holes in 1/4 mild steel and itll be past time for a new one.

Greater than one weekVery nice hole saw. Really tough. Ive cut thru plywood in a few seconds, but it does leave a ratty entrance and exit. Thats OK for roughing in plumbing or electrical work, NOT for veneer work!! This will not cut thru a 2x4 without stopping to remove the plug from the cutter a couple of times. Cuts Aluminum like butter. I use a cutting fluid made for just aluminum. I have cut 3 holes in 1/4 steel plate with no problems. Get your RPM way down for steel. Around 350 to 440rs. Again, I used a sulfur-based cutting oil for Ferris work. The hole saw is as sharp as day one.

Greater than one weekI bought the 1 7/8 inch carbide hole saw. I needed to drill through a 3/16 steel bumper on the back of the jeep. No problem at all. It worked great. I did use oil as it cut through the steel.

Multi-tooth Alloy Cutter HeadThe cutter head adopts a multi-tooth combination design, which is composed of three groups of cutting edges, inner, middle and outer, so that each tooth can be easily stressed during the cutting process, making the cutting smoother and faster. |
Carbide TechnologyTough Tungsten Carbide teeth extend past inside and outside walls for reduced friction and much faster cutting.
|
Stepped Pilot Drill Bit DesignProtect carbide teeth from impacting when the pilot drill bit through the cutting material，Eject the slugs easily, reduce the chip-blocking problem because of the spring design |
Warm Tips:
- Please insert the flat end of the pilot drill bit into the hole of the hole saw and lock it with a screw to effectively prevent the pilot drill bit from shifting, breaking and other problems and prolong the lifetime.
- This Hole Saw cannot be used for Concrete,tiles and stone.
- Do not forget to ues a lubricant so that the bit does not overheat.
