Spetool 90 Degree Carbide V Bits with Tiain Coated 4 Flutes, Chamfer End Mill for Caving V Groove and Sign

These SpeTool V-groove bits are a fantastic addition to any CNC setup. The 30° angle is ideal for fine lettering, detailed engraving, and decorative edge work in hardwoods and softwoods alike. I’ve run them through maple, cherry, and MDF, and the results are consistently crisp and clean. The TiAIN coating noticeably reduces heat and pitch buildup, which helps maintain edge sharpness over long runs. The 4-flute design gives a smoother finish than standard 2-flute bits, especially on intricate passes. Shank fit is precise—no wobble, no chatter. For anyone doing sign-making, inlay work, or precision carving, this 5-pack delivers excellent value and performance. Highly recommended for serious woodworkers and CNC hobbyists who want reliable, repeatable results.

Excellent product and exactly as described

I bought these after I had another brand break on me. I had no issues with these on gnocchi boards. I made 20 or so boards (each with 15ish cuts) and it cut like a champ. If I made more boards I would use a brand new one because it felt like it was dulling towards the end (still cut decently though). To make sure the tip does not snap off, go very slow and controlled at the start. Once the cut is started, you can speed up quite a bit Cant beat the price and the tip stayed strong unlike the other brand I bought

i used it on my cnc router to vcarve some smaller graphics and it worked great

Inexpensive, durable, good quality.

just as good as any other

Used moderately, cuts well but doesn't cut clean engravings in acrylic

Great

I grabbed this SpeTool 60° V-groove router/cutter bit to play around with some CNC sign carving and chamfer work, and honestly for the price it’s been pretty solid. It’s a 4-flute carbide bit that feels decently made, and it’s helped me cut clean and crisp 60° grooves in hardwood and plywood without too much fuss. What I like about it is that it’s nice and sharp out of the box and seems to hold up well through a few projects — cuts are smooth and it doesn’t chatter too badly if you keep your router steady. The 60° angle is perfect for deeper V-cuts, lettering, and engraving stuff. It works great in a 1/4" collet router setup and hasn’t given me issues so far. The TiAlN coating feels like it really helps reduce heat and makes the bit last a bit longer compared to cheaper uncoated ones I’ve tried. One thing to note (just from browsing other users’ experiences) is that, like a lot of inexpensive bits, it doesn’t tolerate super aggressive feeds or really long reach without flexing — so take it easy with feed rates and depth of cut on harder woods. Some folks online also talk about adjusting speeds/feeds to avoid chipping or tear-out. Overall, if you’re a hobbyist or just getting into CNC carving and want a cost-effective V-groove bit that gets the job done, this one is a good budget pick with decent performance for everyday use.

Only time will tell on the durability of this bit, as I use it infrequently I think it will serve me well

Hohe Standzeit. Nutze ihn zweifach, zum Fasen fräsen und als Gravurfräser zum Sauberen anschneiden der MPX Deckschicht. Mit normalen fräsern splittert die Deckschicht von MPX meist großflächiger, als die zuletzt angefräste Fase. Fräst man die Werkstückkontur zuerst als Gravur mit diesem Fräser und so tief, wie man die Fase haben will, hat man Splitterschutz und Fase in einem Arbeitsgang realisiert und eine sauber Kante.

Just what I needed for engraving a chopping board. Arrived next day. Perfect!
