Diablo Arbor Hex 3/8in W/Pilot-2nuts

The headline about says it all...the mandrel didnt couple with the hex shanks out of the package.

Center Bit Is Too Loose, Not Stable. Terrible Cuts. Better Design next time, More Quality Control more Accurate Machining for High Precision Use.

If youve ever struggled with using a screw driver and hammer to extract the wood plugs from a hole saw, you will LOVE how much easier it is to simply pop off the quick release and use the pilot bit to poke those out. Speaking of the pilot bit, however, this one is objectively not up to snuff. Bad metallurgy. They break regularly. Order several replacements or else youre gonna be dead in the water with no warning in the middle of some project

Best hole saw kit pieces that you can customize your own kit with

Worked until it didn’t. Now the saw and bit won’t stay attached. Good and bad design at the same time. It cannot handle hard pressure.

hard to change out the different sizes

What a amazing solution

In my first one the ring keeping the bit inside the fitting broke. Could still use on a lathe but not with a drill press. The bit would fall out. Without the bit the cutter bounced all over the place. The mechanism and principal are great

I like the fact that this tool has a quick disconnect.

Product is well made works great
