SpeTool Down Cut Spiral Router Bit 1/16 inch Cutting Diameter with 1/4 inch Shank End Mill for Woodwork CNC Machine Tools

I normally love SpeTools because they pride themselves on quality but this bit broke the first time I used it in soft wood. I have been a woodworkers for 7 years now so I am positive it was not user error. I am very disappointed as I was not able to receive a refund.

It started off doing well and I thought it was going to be a winner, but about 3/4 the way through the project it snapped. And yes I had the plunge rate and feed rate set accordingly.

worked very well

I used this bit to cut into 3/16 thick mahogany veneer for maple inlays. The down-cut spiral bit made nice clean cuts. I havent used it enough to rate its durability or longevity, but carbide bits typically hold up well.

I like to cut signs (and intricate pieces of signs) with my Shaper Origin, and this bit can get into sharp corners much more effectively than other bits (like the 1/8th or 1/4 inch). I’ve started working with 2.7mm plywood, and this bit can easily cut it in one pass, and as it’s a down cut bit, it seems to minimize the sanding needed on the top edge (which is a big deal for me). The bit is a little pricey, but this far I’d say “Worth every penny!”

Wouldn’t recommend, product snapped within first use of it. Have settings on my CNC to have the machine cut 1/16 of an inch each pass and when it got half way through a 7/32” thick cut through; it snapped. The snapped end looked very granular too so doesn’t seem to be made from a good quality mix of metals, or not annealed properly.

I recently discovered the SpeTool Spiral End Mills and I must say I am extremely impressed with their quality. I have purchased several of these end mills and have been consistently happy with each and every one. I use them in my CNC machine and they have held up well even after multiple uses. The spiraled design provides a smooth and efficient cut, making my machining tasks much easier. Additionally, the end mills are very affordable, making them a great value for their performance. I appreciate that I can purchase a durable, high-quality end mill without breaking the bank. Overall, I highly recommend the SpeTool Spiral End Mills to anyone in need of a reliable and affordable cutting solution for their CNC machining projects.

Not good quality, broke on first cut. Wouldn’t buy again!

Bought this to use on softer woods lile cedar and thin ⅛ birch plywood. Cuts very well and clean and has a half inch long cutting depth. I messed up and snapped it on some quarter inch birch though, I think it may have gotten gummed up with two sided tape holding my project down. I will order another one however because this bit was great.

I love how detailed this bit helps you be able to get when doing detailed wood projects.
