Spyder Hole Saw with Rapid Core Ejection | Review

Lose the Screwdriver?

Once a mainstay for plug removal from hole saws, the screwdriver, Spyder has put an end to this rocky relationship with the introduction of the Rapid Core Ejection system.

Rapid – Check

Core Ejection – Check

System – Check – It also has a Rapid Switch component.

How it Works

The operation is two-fold: an oversized pilot bit and a push-button integrated into the hole saw arbor.

Pilot Bit

Most pilot bits are about 3-1/2” but, Spyder’s bit is 7” in length. It features a positive-stop detent so the cup is securely fastened into place. Users simply press the button and situate the cup until it seats and let go of the button. Once locked in, it is ready to roll.

Rapid Switch Component

This is the heart of the Rapid Switch component. Button – Seat – Button. Quickly swap out other cup sizes. It takes longer to locate the other hole saw than it does to change them out.

The action is almost the same for the Rapid Core Ejection. The one twist is that instead of moving the cup forward, the cup is pulled back (hence, the longer pilot bit) to expose the cut material. The plug slides right off the pilot bit and it on to the next hole.

Testing this out with a friend, he couldn’t believe how quick and easy it was and asked what he was supposed to do with his hole saw kit as he didn’t want to back to the old way of removing plugs.

In Action

Spyder sent two samples, a bi-metal HSS saw and their TCT (Tungsten Carbide Tipped) model. All tests were performed using the DEWALT 511 to eliminate charge drops.

The 1-1/4” bi-metal hole saw performed well boring into a 2” x 4” in just under 10 seconds, 9.8 while hitting a knot in two separate occasions. The third time fared a little better by evading a knot and broke through in 9.2 seconds. Using a competitive hole saw in the same 2x4, it came in at 8.5 seconds.

All cuts were clean with limited blow-out on the back side of the board.

While the competitive cup had a limited time difference, it was the plug removal that put Spyder ahead. It only took a couple of seconds to pull the plug from the Spyder cut. With the competitor’s cup, it had to be removed from the drill using a chuck key and the plug was punched out from the bottom of the arbor.

Now, when using the TCT hole saw on the 2x4, sped through the wood in an impressive 3.4 seconds. In other words, it covered ½” every 1.1 seconds.

Watch how quickly it cuts

It didn’t strictly cut through but kind of chewed as well. Note the difference in the plugs, you’ll see that the TCT raked the core as opposed to the bi-metal saw that clearly cut around the material for a cleaner plug.

While this portion wasn’t timed it didn’t take long to make a hole in the 1-1/2” masonry block. It constantly chewed up and spit out the removed materials. The entry hole was quite clean and the exit hole has some extra blow-out but for all intensive purposes, the hole would go largely unseen.

When it came time to remove the plug, there wasn’t one. The hole saw effectively made small chunks that were discharged during the cutting process.

Final Thoughts

Bottom line.  They work and they make removing plugs much simpler. With cups ranging from 3/4” to 6-5/8” there is something for everyone looking for a complete system that saves time and frustration.
