SpeTool 5Pcs Tapered Ball Nose Carving End Mill 1/8 inch Shank 0.25MM Radius (0.5MM Diameter) Tips 3D Woodworking Tool CNC Router Bits

I had been trying to do some fine engraving in brass using 0.1mm tip flat grind engravers, and struggling mightily. Even though these tools have a bigger tip, I re-worked my design to accommodate the size difference and what an amazing difference. These are cutting much better, and LASTING. After a few test cuts the tip looks perfect at 40x macro. The old point engravers would lose their tip almost immediately. These having two flutes helps to. As long as my design and handle the larger size, I'm glad I switched. Running at 24k rpm, 0.25mm depth of cut, .5mm width of cut.

Excellent quality and fast shipping!

Why did you pick this product vs others?:I used these all the time for my small business, they cut well and can the 2 flute design works great with ABS, I cute ABS enclosures on my bench-top CNC. These bits are real workhorses, I can get over 25 enclosures, so thousands or MM of cutting 3.74mm thick ABS plastic. My own mistakes are the only reason I have to change bits, otherwise, they just keep going and going.

Strong and sharp, lasting for a very long time

I do alot of 3d cnc milling on walnut. This bits are sharp and last along time. They leave a amooth finish and get into thoughts hard to get spots. Ive tried some other brands and these are the best I have found so far

Worked great after a 13 hour carve. Still going strong. I'm impressed.

Spetool bits are my go to.Great quality. We'll worth the minor extra cost

For me they allowed me to cut out thin pcs without difficulty for finer workmanship. I know they have multiple uses.

Good ball nose geometry, excellent finish

Con estas pequeñas herramientas de grabado me apoyo para marcar y grabar bases de acero 1018, 12L14 y de aluminio. Trabajan excelentemente y duran 20 veces más que un cortador vertical de carburo del mismo dímetro. 18,000 rpm, lubricación y avances de 200mm/min X 0.125mm (0.005") de corte por pasada y durarán muchísimo

I am very impressed with the detail that can be cut with one of these. They are far stronger than my 1/16th inch bits and yet the point tapers down to about half that size. I will even through these in my rotary tool (dremel) and use them for fine work. I have been using the same one for cutting wood almost every day for 2 months and I have not noticed any issues with it yet. I still have a cut on my hand from lightly grazing this bit with the CNC turned off. Great quality all around!

Cuts perfect

I was a little concerned about the small size of these cutters, but they end up cutting great in softwood and corian.Can't beat them for the price.I will buy more cutters from SpeTools.
