SpeTool 2 Flute Square Carbide Machine Power & Hand Tools Review

pretty good bits for the money. I had no problems using them on my xcarve. Definitely better than those sold to inventors

These are very sharp and clean cutting inserts used for milling copper from copper clad FR4 laminate. They break if mishandled, the small 0.030" drill bit is brittle.

I use them with a Sainsmart 3018 CNC for engraving and cutting brass parts. I'm using both 0.7mm brass sheet and 0.5mm thick brass blanks at 25mm/min so it's quite slow but the results are very clear and reliable.

Very sharp bits. I have used a different brand of bits that are much cheaper and had no idea what I was missing. Very sharp bits. Had to look twice for the noise reduction when I used the first one. I thought it broke, it was a lot sharper than the bits I used.

I love these bits. They are sharp and cut nice and clean. What I particularly like about them is that they are strong beats. I only managed to break one because my machine malfunctioned and crashed into the workpiece at full speed. I even once accidentally programmed a step down slightly longer than the cutting length of the bit and to my surprise it survived. I will buy this again.
