SainSmart Genmitsu 10Pcs Nano Blue Coat Flat Nose End Mill CNC Router Bits, 1/8" Shank Spiral Upcut 2 Flute End Mill Set (3.175 x 17 x 38mm)

Perfect as expected, I bought these as a backup to the ones I already have as I’m pushing them hard but they are still working well and very durable and seem to be keeping their sharpness. I clean them when needed by brushing them with a wire brush that can help unclog the buildup of particles on the teeth sometimes with certain materials. The main materials I have used these with is MDF and Cast Acrylic which they work really well with.

These are great little end mills. They kept their sharpness after several jobs

not that good at cutting aluminium, cant do more than about 0.3mm depth of cut without excessive vibration. With the same settings other 6mm end mills absolutely slice through at 2mm depth of cut even cutting soft plastics like ptfe, the surface finish is poor and the edges of the cut show strands and tearing. Put in a good end mill and the results are far far better

After 24 hours of constant machining mdf I'm still on the first cutter! 2.5mm depth of cut at 100mm/second!

Use these bits a lot on my cnc machine not the cheapest but good solid and with a good life. Will buy again and again and again cant say more

Quite a bit of tearing when used with hardwood vs other similar bits.

Study, cuts well

I guess these are regrind.. The tools are not all the same length..the flutes start at same length from end of shank but the overall length is not the same...regrind.. These are well finished and the blue coating even covers the ground face.

Cortan muy bien en madera

Qualität Top und sehr pünktlich zugestellt.

透明アクリル 結構粗悪アクリル 3tを切断するために買いました。 先端が0.5から1mm出るまで下げて ワンパスでカットできました。

良いと思います。

安くて加工に問題なし
