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

cuts great on cnc, build quality is great. works really well for making small detailed carves

If you do a lot of intricate CNC engraving you will find this to be an often needed and invaluable tool. They are difficult to find, very fragile, and quite expensive considering the lack of durability.I try to use a 1/4" or 1/8" tool for clearing and only use this tool for cleaning up the detail edges. Even then, make sure you are taking VERY shallow cuts, and slow your feed rate down to like 30" per minute. Even having taken all those precautions if your cut takes you through a knot, or you are using particularly hard material like hickory, you will snap these off occasionally. If you are doing custom client jobs, make sure you keep more that one of these on hand and tread very gingerly with them.If you are just doing fine engraving and don't need the straight bit, the 1/16th tapered ball nose is far more durable, and might be a better choice for some jobs. Even for inlays I usually use the tapered bit. You just have to experiment a bit because you'll have to make your pockets a little undersize to compensate for the taper. Once you get it down, it a much better way to go for inlays. The taper actually gives you tighter inlays and less gaps.When you do need the straight edges AND tight corners (epoxy fills, for example) this tool is invaluable. I have bought several of these in spite of the breakage, and will continue to buy them.

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!”

love the material and excellent customer service! these are great! and for a good price!I use them a lot for my small cnc projects, my personal fav is the compressions bits! wow! there amazing and strong!

Bit was as described and worked perfectly! Sharp and smooth cut

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 have used this bit on several jobs so far and if has worked as well as a higher priced bit that I recently dropped and broke. This bit is about 14 dollars less expensive and does a great job, although the feed rate is not as fast as the other bit.

worked very well

Looks good

Sadly I broke this bit after about ten cuts but it was 100% user error and I ordered another straight away I was that impressed. Its a very thin working end so go slow!

Using to cut 2mm Acrylic - Perfect - Best value for money.

These bits can be pretty fragile! I tend to run my machine pretty full out and I still have this one so it must be pretty good if my impatient self hasn’t busted it yet. Will definitely buy again
