Sharp, Reliable, and Long‑Lasting
Number of Items: 2
These 3‑flute spiral bits are excellent for precision CNC work. The 1/8" cutting diameter makes them perfect for fine detail, while the 1/4" shank provides a secure fit with no wobble. The extra‑long design gives plenty of reach for deeper cuts, and the spiral geometry clears chips efficiently, leaving smooth edges with minimal fuzzing. I’ve run them through hardwood and softwood, and they stay sharp even after extended use. Having two in the pack is a nice bonus—great value for a tool that feels solid and dependable. If you need accuracy, durability, and clean results, these bits deliver exactly that. ... show more

Quality bit just go slow

It's a nice size for an 8-in router bit the depth of cut works very well I have a nice coating on it which gives a good durability and seemingly good quality to it being such a long skinny bit you need to ensure that you the feed rate is very slow seemed like it was good for the money and the sharpness was there when I opened the box ... show more

Longevity!
Number of Items: 1
I normally buy 1/8" endmill bits in 1/8" shank. This time I purchased the 1/8" endmill with the 1/4" shank with the NACO coating. I have used it on 18 CNC profile cutouts that are 1.25" thick Cherry and Mahogany hardwood. This is the best 1/8" endmill I have ever used. I normally use the 2 flute for hardwood, this is 3 flute, I adjusted my speed and feed, super clean cutting! I ordered the set of 5 as a result of using this one bit. I will only use this particular bit for all my future profiles cutouts that require 1/8". It cuts clean and it lasts a long time. There is no gumming, I have not had to clean the bit at all after 18 cutouts that require 12 passes for each cutout. Longevity and clean cutting are strong factors in CNC. I strongly recommend this product. Remember to adjust your speed and feed to accommodate 3 flutes in your tool database. ... show more

Brittle spirals
Number of Items: 2
I have ordered these twice and they break in the middle of a cut right at the shank. I'm only taking .125 inch at a time. They seem to be pretty brittle. I like the longer cutting edge for my toy making operations on my CNC where I am cutting patterns at 1 in and 1.5 inch, but if they are going to continuously break they are not much help. ... show more

Up Cut Bits
Number of Items: 1
I was not able to find anywhere in the description but these are upcut bits. It did not matter for my project but I am sure most CNC folks would like to know. I needed a 1/8 inch bit where the spiral flutes were over 3/4 of an inch. This bit has more than that but I could get them next day so I bought 2 of them. Since some reviewers said they broke, I ran my cuts at 90 feet per minute with 7 equal passes. Got a very nice cut and no tear out at the top. Was using 3/4 inch plywood with an oak finish. Not sure how long they will last but they did fine on this particular project. ... show more

Good Bits, Go Slow, Clean Cuts
Number of Items: 2
Sharp bits. Listen to other reviewers, watch your Spindle speeds, Feed and Plunge rates, go slow. Just used them and they cut through a complex design on 1.00" solid oak, no burning, smoking, as well as .75" Padauk. You can hear sharp bits that are not stressed when you get the speeds/feeds correct. I typically buy Amana, or Whiteside bits and these cut very well. ... show more
