Compression Bit

These little bits cut better than a lot of the more expensive bits I have. I am using them in my CNC machine and I can use a faster travel speed, a deeper pass depth and a larger stepover than I thought would be possible with a bit this small. The only issue I have had is that I broke 2 of them by accidentally hitting a clamp. I also ruined one trying to cut some acrylic. It cut the acrylic just fine but I had the speed set wrong and I burned the bit beyond any further use. I am going to buy another package of them before the price goes up, although I would probably buy them even at a higher price.

Great bit, exceptional value, perfect for cutting clean circles. A light touch of sanding after you are done and you are ready for the next step in your project. Will definitely buy again when needed.

Using these bits in my Fox Alien CNC. Cut quality is good. Life seems to be good (no dulling after 5hrs of cutting in laminated hdf). Time will tell but for the price you can't go wrong

I have made only a few cuts with these bits, but the performance and accuracy of the bits was good. At this early stage, I would purchase again.

Worked well in my cnc machine for cutting and milling plywood. Size was correct and fit my chuck well.

I run a CNC based business and have tried almost every brand of endmills available. These bits are the best I've found. The value is beyond great. They leave a smooth bottom in pockets and last longer than endmills several times the cost. Normally I find that cheaper bits sometimes cut just as good as the top price bits but don't last as long, not these Hozly bits they both cut better and last and have a longer life. I buy the 6mm, 1/8th regularly and just received the 5/16th. It's hard to believe they are this good for the price but it's true. The other day I misjudged and hit a aluminum clamp with the bit and it just kept going and I let it finish the tool path and the cuts were still great!

I am cutting precision templates in MDF using a hobby-sized CNC router. Prior to this I had used solid carbide upcut bits from another manufacturer. They left a fuzzy cut requiring lots of hand work to clean up. These bits leave a perfect cut both on the top surface and in the bottom of pockets. I doubt that a more expensive bit can do much better, if any.

NOT 6mm. I purchased this to make 6mm dados for 6mm MDF shelves. I measured with digital calipers. These are 5.71mm which means there is not way the MDF will slide in. I placed the bit on a surface next to a piece the MDF and it is obviously not going to work. Returning! This was an ‘Amazon Choice’. WHY?
