SpeTool Spiral Router Bits Down Cut 1/4 inch Cutting Diameter, 1/4 inch Shank Solid Carbide CNC Bits End Mill for Wood Cut Carving Engraver

I love using these bits with my CNC. It can really dig out the wood and does a clean job. I’ve used it on several projects and it stays sharp.

Great Drill bit. I used for CNC Shopbot and it worked great.

I bought this end mill for use in my cnc machine exclusively for wood milling. I use mainly bits from amana tools but occasional buy an off brand bit to try out and was pleased with how this bit has continued to cut decently after many hours. I don't think it cuts as clean as a high end bit, but its so close that I'll be buying more of these in the future.

sharp clean cuts, appears to last through numerous projects though i don't subject it to that many

I bought this to use on my CNC machine for making flags and signs. It cuts very well and continues to do so after many cuts. The price is great and the quality is even better.

I've bought several sets of these CNC bits. We do a lot of profile cutting on a shop bot buddy. They cut cleanly and last quite a long time. And they're much more affordable than the name brand bits. I haven't had one break or prematurely wear out for reasons other than user error. Measure twice, cut once!

The down cut spiral router bit leaves a nice clean top edge. I'm using it in a handheld plunge router with a circle jig to cut holes and recesses in DIY speaker boxes. I don't really have anything else to compare it to but it seems to be sharp, decent quality and cuts smooth. I cannot comment on how long it stays sharp because I've only used it a few times.

these are very good bits

My original spiral bit broke so I ordered this one and it arrived in two days. This is a good quality spiral bit. I used it to slot a bunch of maple and black cherry wood and it performed flawlessly. Happy with my purchase

Bought one of these as I was a bit skeptical about the cutting quality. But they cut clean. Then I broke the bit when it hit a buried screw! (That is something to watch out for!) So I bought a pack of 5.

Ottima fresa taglio pulito e molto silenziosa

Prezzo Qualità ok

I have bought many of these bits from Spetool and thay are a consistant quality time after time and Spetool is my "GoTo" supplier. Their web site has a downloadable catalogue which can be imported into Fusion360 which is a great time saver.
