  • Been machining for 10 years
Naturally when you’ve been machining for 10 years you think you know better than others, I read the reviews and thought they were just amateurs with the wrong speeds and feeds. So over the period of my use of the surface bit I started way way easy and slowly picked up doc and feeds. Today after running it at these speeds for a few projects and grabbing just flipped the edges of the inserts a few jobs back the tool bent over. I can now say for sure they are garbage and not worth the money. I’m so disappointed because the return windows just closed. ... show more

  • Works great!
Needed to surface my waste board. I had an older bit I had used once. It did a terrible job. Once I shaped them out with the new bit. It was a night and day difference.

  • Great bit, if you have the right router.
The bit worked great, right until it warped. I have an older craftsman router and the bit would only go in the collet until about 3-4 mm of the shaft below the "insert in router to the line" line was still sticking out . I figured that would be sufficient if I was careful with the amount of pressure I put on the bit. I was wrong. It worked better than any other router I've used, right up until I pushed it too fast (was working with a small oak slab, so that did not help). The shaft warped a bit and developed a distinct vibration, becoming unsafe. I put it in a modern trim router where I could get it to the "insert in router to the line" line and tightening it. The vibration went away, but the bit was then too short to do what I needed. So, if you have an old Craftsman An likely other brands), this bit is not for you. A slightly shorter shank would make this bit MUCH better. ... show more

  • Bad product great customer service
This product did not last very long it bent almost immediately after installing it and running it for a few hours. {Update) The company offered a refund for the product. this product might work better with a deeper collet.

  • Blades Are Cheap
I thought this would be a good surfacing bit for my router sled. I made one pass and the blade cracked and chipped .. Do not buy this product

  • Not for the end grain
It didn't take a long time to find out it is not for the end grain flattening.
