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

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.

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 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.
