30° 0.1mm Tip Conical V-Bit

I've used these on pine, mahogany, brass and slate. With careful attention to feeds, depths and speeds, I've had excellent results every time. Hobbyist CNC with a Genmitsu 4040 Pro MAX and Inventables Easel.

Ok quality, but very different lenght and shape. Bit converning for a milling tool. Will buy different next time.

I've milled several PCBs without breaking one and it's still sharp. I find the 30deg angle better than the 20deg as it gives that little bit extra width to the cut. I didn't have much success with cheap 20deg ones.

First time using a small CNC for work in brass, and these cutters were a bit of a gamble given other reviews. Yes, I broke the first one I tried but that was down to me not getting the calibration right on my machine (WCS vs MCS, doh!) The next run was great though.

The headline description of these says 'carbide' but I see in the description that they're made of alloy steel. This fits with my experience of trying to use them for metal engraving (aluminium) - They aren't very sharp and haven't got a good enough edge to cut metal. Probably OK for wood & plastic. Would not buy again.

Works well, good quality of cut

The bits drill clean holes

Good clear lettering when engraving aluminium.

Ottima qualità. Solo per finiture. L'angolo a 30° è condizionante.

gute Werkzeuge zum günstigen Preis

Overall I'm impressed with these bits. The value far exceeds by expectations. Based on some other reviews, I was expecting sub-par performance from these bits. However, after 3 jobs I see great results and will continue using them. 10 bits at this price is a tremendous value. Update: After some additional time with these bits, I've noticed that they have an issue with clearing chips while cutting hardwood in particular. When cutting a 5mm deep v-channel in maple, the resulting channel is hard packed with dust/chips. Adding an additional finishing pass helps marginally, but there is still lots of manual work to clean out all the chips from the cut. I still recommend these bits since they are great for the price, but know that more cleanup work than expected may be needed when cutting some materials.

Boa qualidade.

Great. They engrave wonderfully. There's enough in this kit to do a ton of engraving.
