20/30/45/60/90deg 0.1mm Triangular CNC Router Bits Set, 1/8" Shank Engraving Carving V-Bit with Nano Blue Coating Sharp Pyramid Bits for Acrylic Wood MDF Aluminum Lettering Sign Making

I use these to v-carve high detail lettering in oak, walnut, and other hardwoods and they work brilliantly. Some materials like beech can dull a bit really fast, but these seem to hold an edge longer than other brands I've bought in the past. The blue finish wears away in the end, but that in no way affects the cut quality. These are my new go-to v-carving cutters for small-detail CNC engraving.

Perfect for pcb milling. They seem to keep their edges quite well and cut clean edges on the tracks.

Value for money

Good sharp hard point tips. Do the job well

These bits cut really nice and give a great finish.

My husband was pleased with it

At least 4 of 8 bits are not centred which is ridiculous I never had to check if bits are off-centre before I guess I have to start now. I ruined a piece I was engraving and took me a while to figure out as again I never got off-centre bit before so I kept on checking my programming and settings.

Good quality cutters. Do a nice engraving cut.

Worked great. Engraved stainless-steel well, lowered cut rate and depth plus lots of cutting oil. A few passes, the cut came out clean. Good buy .

アルミに細い字を彫りたい方にお勧めです。

I used these for PCB trace milling and they make excellent cuts. These are three flute bits where standard flat V bits are 1 flute.

Ottimi. Utilizzati per lavorare alluminio su Cnc. Feed 500mm/min, doc 0,2mm, rpm 15000. Serigrafia riuscita perfettamente.

Le punte ancora non le ho provate, quindi posso descrivere la mia esperienza d'acquisto. Il corriere con molta premura mi ha recapitato il pacco a casa, dico questo perchè l'indirizzo di consegna era un altro ma al momento non era possibile accedervi. Le 3 stelle sono perchè ero convinto di ricevere una coppia per tipologia come illustrato, invece se leggete nella descrizione si tratta di 10 punte da 30 gradi tutte uguali... e a me servivano quelle a 90 gradi. pazienza. significa che distruggerò queste... però che scocciatura.
