Changed my straight knives to the SpeTool helical head on my planer and it is so much quieter and butter smooth! Plus it has more cutters than the shelix and costs much less! Well worth the investment.
I had bought 2 sets, 24" and 36" . I found them to be very protective and easy to use, they do keep your work from moving, and yes use a piece of scrap wood on ends. I would highly recommend to use this product. For me it was worth every penny
This CNC cutter is well made and robust in use. It cuts clean in both pine and oak and I cut to almost the full depth of the cutter at a variety of speeds and feeds. Highly recommended.
so easy to use and it's portable which makes it so convenient for many projects. But the best feature is the smooth motion and accuracy
I have several of these bits, and they've only ever given clean cuts. They last a decent time too despite abusing them with hard/exotic wood.
