Not a bad little bit
If you follow the chart for speeds and feeds you will be just fine. I only do .01 per pass on depth but I’m just paranoid when it comes to tiny bits like this. Better safe than sorry. Have ran multiple jobs with this bit in various hardwoods such as PurpleHeart, Paduak, Maple. I’m starting to see that the corners are shiny which means the coating has come off or corners or worn down. It’s an ok bit. Not great but not bad. Not sure why so many people broke this during their first use. It’s a tiny bit and you need to use it per specifications if not baby it a bit. ... show more

Broke during 1st use
First time using it and it broke after about 10 minutes of use. I did very shallow passes and then it just snapped off. It was cutting so smoothly, that I almost didn't realize it had broken off. Wish I could return it but it's past 30 days and even though I bought it over a month ago, I'm just using it now. Bummer! ... show more

Blue Nano Coated Solid Tungsten Carbide 1/16th" x 1/2" Spiral Upcut 1/4" Shank CNC/Router Bit
I enjoy a hobby that requires using high speed rotary burrs to shape and define wood, plastic or softer metals (copper, silver, gold). This is a specialized Blue Nano Coated Solid Tungsten Carbide (TC) 1/16th" x 1/2" Spiral Upcut 1/4" Shank CNC/Router Bit with a very slender cutting spiral and sharp end. The blue nano coating is intended to reduce heat and wear. It certainly could be used very carefully on a trim router though it is more intended for CNC milling. For a precise hole this could be carefully plunged but as it is so very thin there is no doubt that it would break easily. I wouldn't try this bit on a handheld rotary tool as TC is brittle and the cutter is very small with no flex. I Recommend this Jiiolioa Brand S21A1G Standard Spiral CNC Router Bit 1/4-Inch 2 Flute Up Cut End Mill 1/16" X 1/2" X 1/4" X 2". Small bit for my tool shop; pricey. I hope you’ve found the information and my review helpful. ... show more

cut well but broke prematurely
The bit was cutting great, I was cutting at 600mm/m with a heads speed of 24k rpm and 1mm passes into cherry wood. It did most of my first project and snapped at the end of it. This was the first time using this bit. I was so impressed with its cutting until it snapped. Seller what are your recommended speeds an cutting depth? ... show more

Broke after 1hr 18min on the first job
Worked fine then broke after 1hr 18mins on the first job it was used. Wasn't worth the price paid.

Very delicate
I am too afraid to use this on most materials on my CNC router. Works great on foam which is all I dare try.

Great For Detailing
If you’re into woodworking like I am, this router bit is a great addition to your collection. It’s perfect for fine detailing or doing intricate cuts on hardwood. The bit bit seems to be well made. It’s made of solid carbide steel which should hold up for extended use….if it doesn’t,I’ll report back. And the sizing is standard for any CNC router which is good. The company claims the bit doesn’t overheat, but mine got pretty hot after a short time. I just hope it doesn’t warp with extended use. Only time will tell on that. So far, I’m happy with this router bit. It does a good job with small cut. I just hope it lasts. ... show more

Great for CNC Router Pocket Clearing Tool Paths
I own a CNC Router which requires many sizes of Router Bits to complete some projects. The finer the detail, the smaller bit size is required to produce that detail. The clock project pictured above is a good example of that fine detail. The clock is 24" in diameter however the cat tails and reeds vary from 1/4" wide to 1/16" wide. The majority of the clearing cuts were made with a 1/4" bit. The Jiiolioa Spiral CNC Router Up Cut End Mill 1/16" was used to get into and clear out the very narrow areas for the fine detail. I haven't used the bit enough to speak to the durability & longevity of the end mill. On this project, its sharpness left very clean edges on all of the cuts. It never overheated during the 45 minutes required to complete the clearing toolpath. The price is slightly less than I pay for comparable carbide bits of this size. I will update the review in the future if needed. ... show more
