I got a 30' and a 60' single flute bit from them. not bad I've only tried the 60' so fair in some hdpe. it's not perfect but a lot better them what I've been trying. so, I'm happy thus fair. had to do a little bit of clean up with a wire brush. but nothing like what i had to do before with a 2 flute. when the 30' comes in ill give it a try too, see how it cuts.

This bit is well protected with a case and a plastic sock for the flutes. There is no coating, rather it is just bare steel. The flutes are very straight and sharp and the tip is flawless.

This a very fine tipped bit. When using it in HDPE plastic at 18000 RPM, and 40 IPM, I get a decent detailed, cut without too many artifacts.I can't say how long it will stay sharp, but it should be good in softer plastics for quite a while.I'm happy with it for my application.

I can't really remember when SHARPRO first popped up out of nowhere, and started offering high quality carbide bits at prices that didn't make me feel like I was being taken to the cleaners.I tried one, and it was Good... I tried another, and it too was good... Fast forward to today? I have over 60 SHARPRO bits in My CNC bit collection.If You're familiar with CS Onsrud, Or LMT Belin, or any of the other premium brand bits, then you know that If you buy 2 bits, you'll not only not get change back from a $100 bill, you will in fact probably be short about $20.So is there a $50 difference in performance between these and a "premium" bit?First off, I consider these Premium bits, secondly? The answer is simply NO!I cut plastics, wood, and even Aluminum with My CNC, and I am being completely honest when I say that It is difficult to see any difference in quality whatsoever. In fact, I find that because I can Buy 4 SHARPRO bits for the price of one big name bit, I'm not as inclined to ride that bit until the bitter end like I used to, in an effort to get every single penny out of them.Now? I just cut Myself a little bit holder, and I mark the bits with an "A" "B", or "C" to denote the life stage of the bit.Whereas If I'm cutting a $600 sheet of 1" PolyCarbonate, I'm not taking any chances.. I want the newest sharpest bit possible, so I'll grab an "A".If I'm simply cutting pieces for a cabinet or something like that? I'll use a "C", because I'll be finishing the edge anyway.Just Try One! Get your favorite bit, and run the living daylights out of it, and tell me what you think.Me? I think these guys have got a goldmine on their hands! As long as quality stays the way it is? I have no desire to be buying expensive name brand bits ever again.

The bit does not make clean cuts.

I like this bit! Just tried two other bits, both cost more than this one. And both are not worth spit. This one cuts instead of shredding the wood. I guess I'm either sticking with Sharpro, or I'm going to have to shell out $100 for another (replaceable blade) bit. The first photo is the Sharpro bit, not the best choice of wood for this, but the wood actually cuts pretty nice, very little/easy clean up. The other photo is the Binstak bit, look how shredded the wood is, impossible to clean up.This bit, is a great value. Not sure how long it'll last, but even one project, it'll be better than those other two.

I was surprised at how well this bit works. I use it to start my sign outlines… very fine tip but it can cut quite deep.

This bit is strong and straight. I've used it to v-carve on my hobby CNC that utilizes a name brand palm router. After a few projects, it still feel and cuts like it's sharp. I ran it at 0.080" depth per pass, 35" per minute, at 18,000 RPM.By design, this isn't a down-bit, so there are some fuzzy edges depending on the direction of the grain. However, I deal with that by routing slightly deeper than I want, then doing a light surface sanding. If you plan to paint the carved sections, I learned to get wide craft masking paper and carve right through it.
