🛠️ SpeTool Engraving and Cutting Tools for Compression Diameter Grinding Review

Pretty good general purpose cutter leaves a bit of blur on the edges but cuts very cleanly vertically. I would buy it again.

CNC cutting 3/4" plywood. Smooth top and bottom edges. Can cut faster than I thought. Cutting in 1 pass (at slower speed of course) saves machine time compared to cutting in 6 passes on a vertical edge drill, I recommend

The worst compression bit I've ever bought. Not recommended for CNC use. Many tears at the top edge. Terrible cut quality. the tip of the bit is too high on the bit. The first cut should be 3/8 inch.

Okay, maybe two after one cut depending on how you want to count it. The beat really fell apart. I managed to disassemble these two large parts. But more of them probably went deep into the surrounding walls. I used a Makita router at speed 2. Not so fast. I mean it's a pain because I lost 20 bucks. But it could also result in injury or the breakage of something more expensive.

Great product so far! I use this bit on my Shapeoko XL and needed a new 1/4" bit to cut profiles. As you can see in the picture this bit was used on the left insert and my old Amaña 1/4" Drop -Thread bit was used on the right insert. As you can see the difference when you zoom in, this new bit is far superior to amana. But Aman's set of teeth is older and most likely a bit boring, and just a run-down set of teeth too. But I have to say that I am very satisfied with these Spetool compression…
