Spyder 1/2in Hex 10 High Speed Steel Hole Saw Arbor - For Wood, Plastic, Metal.

these arbors with the 3" hole saw work great for cutting plugs out of Zoysia grass . I was able to cut 10 trays of 12 plugs in under an hour. GREAT TOOL . must use heavy duty 1/2" battery operated drill.

We bought this to do holes for our entire new construction house. I am very pleased with the ease of removing chunks of wood. quick, simple, and effective.

Simple to use and wish I had this instead of other hole saw jigs. Does exactly what is described. Buy it, you will not regret it. Great quality and solid.

A little hyperbolic, but this is one of those rare tools that handles a long standing problem with simple elegance and good design. It's secure, well made, and makes removing the plug simple and reliable. Now, if I only could reclaim the hours I've spent trying to pry stuck plugs out of hole saws... Don't think about it, just get this, you will be happy.

worked as expected

I make a lot of roof penetrations. Spyder is the best in my opinion.

Worked decently well

holy crap. How have I lived my life this long without one of these? I have a hundred hole saws, this is far and a way the smartest design I've ever seen. remove saws with a push of a button, clearing the cutout is super easy. well built. I'll be slowly as I need them converting my whole pile to saws that will fit this bit.

great arbour, wish someone had thought of it years ago

SO SIMPLE TO REMOVE BIT AND EXTRACT WASTE LOVE IT WOULD RECOMMEND ANY DAY THANKS

Good stuff

The arbor bit fell out after the first few uses through dry clean wood. Clever design but bad quality product.
