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.

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.

Very good set of bit and at a great price. They worked very well in my CNC router and produced the results that I was wanting.

These worked great for engraving brass and aluminum for a set of wax seal stamps I was making! I used Vcarve to generate toolpaths but these little mills can do surprisingly fast. For feeds and speeds I had 10 IPM and 0.01 DOC in both aluminum and brass and I never broke the cutter (in about 2.5 hours of machining).

These bits, along with a better quality hardwood, have caused my CNC carves to come out sharper.

I bought a 5-pack of these bits for $20, not expecting much. The first bit held up really well through a 10 hour hardwood (cherry) 3D carve. Still sharp afterward. I used the same but as an end mill to cut out some laser cutting design from 1/8" plywood. The bit is still sharp. If the other 4 bits in the pack hold up this well, they're a steal at $20.

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.

Good ball nose geometry, excellent finish

Für den Preis Spitzenware.

My go-to bits for high detail relief cutting.

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

The grind seems to be good, but the tip diameter is actually 2.2mm. It is OK for my use and could be just my batch, but do make sure you measure them before using.
