Finally, a hole saw that doesn't get stuck! #tools #diy #hacks

What happens here

Enlarging an existing hole precisely can be tricky, but the Spyder Quick Eject Arbor System offers an innovative solution by allowing you to stack hole saw cups. First, select a smaller hole saw cup that perfectly fits inside the existing hole and a larger hole saw cup for the desired final diameter. Attach the smaller hole saw cup to the arbor. Then, press the quick eject button and slide the larger hole saw cup over the smaller one, nesting them together. The smaller hole saw cup will now act as a perfect guide, centering the larger hole saw precisely over the existing hole. This ensures a clean, concentric enlargement without the hole saw wandering.

Goal: Precisely enlarge an existing hole using stacked hole saws.

Re-engage it. Finish it just like so. Wow. Um our longer pilot's going to allow you to actually stack two of these cups. You just press the button, nest the cups together like so, and then your original size is going to be your new pilot or a guide to just perfectly center it. So, you can enlarge the hole like so.
