TEMO Carbide Downcut Inlay Router Bit 1/32 Inch Diameter

These work great. I use these on my Shapeoko cnc on wood signs and I’ve yet to wear one out.

Great bit, work perfect for my fine detail project on my CNC router, used slow feed and speed with perfect down-cut quality.

I purchased two of these bits and both of them broke just after a couple of uses.

I reduced all the speeds and feeds specifically for this bit to make sure it won’t break in the stock, but unfortunately, it’s very fragile and broke once it touch the stock before even the machine starts moving. I don’t recommend this bit, waste of money and time

Got these to do some detail work on my 3018 Prover and they do seem to work as expected. I have used the 1/8, 1/16 and 1/32 so far and they all cut smoothly. Note I am being extremely conservative on cutting depth and feed rates as Im not ready to test the limits of these, especially the smaller ones. I program to cut the main areas with the larger bits then come back and do increasingly tighter profiles with the smaller bits and it seems to work well. Am cutting on red oak right now and they cut smooth and clean.

Pleased

I used the 1/16 downcut bits to cut mahogany and maple. The attached pictures show the mahogany, all of which was cut with the 1/16 bit. The maple was largely cut with a 1/8 bit from a different maker, but the small holes in its center were cut with this 1/16 bit. I couldnt be happier with the results. No tearout or chipping at all. I ran the bit at 18,000 RPM and 36 IPM.

This is my favorite bit. I use it on my CNC to cut small stuff with a great amount of detail with minimal sanding. These don’t break unless I do something dumb, like dropping them or forgetting to switch the router on...

I ordered three of these bits given their price and that I mill a lot of items so its understandable I can go through them quickly. Unfortunately, I feel I broke a record by breaking all 3 within 24 hours of them being delivered. 2 broke almost immediately during milling jobs while one was able to actually complete a job, but it eventually broke immediately on the following job. I am cutting exotic wood species and actually had success with these very same bits and had one that lasted me for about half a year. I am very careful with my equipment and I tend to configure jobs to run at a more cautious level, but even those parameters are too intense for these week bits. These are the most unreliable mills I have ever used. I will be demanding a refund for these weak, faulty products. Do not order these!

... but it broke right at the shank essentially as soon as it touched wood for the first time, before it had a chance to move in the x or y. This was just my experience and I have not used this brand in the past, so maybe it was a one-off thing. With a cutting diameter this small, Im sure there are a lot of breakage issues due to user error with improper feeds and speeds. However, I am probably more conservative on F&S than I need to be, especially with specialty bits like this. So I would need to test a few more to determine where the issue lies. Unfortunately, I dont have any more of these right now, so I may try another brand and see how that goes. I will update this review if I get another one and have a chance to see it in action.
