  • reliable and worked as advertised
Pattern Name: Surfacing Bit Size: 1/4" Shank-1-3/8" Cut Dia. (2+2 Inserts)
this thing works better than I thought it was going to. Had a 5 foot wide red Oak cookie that it cleaned down beautifully. 1st time I did this and it cut like butter. Skeptical at 1st because it was my 1st time but no problem. I would buy this again good value.

  • Quality will always beat a cheaper price
Pattern Name: V Bit Size: 1/4" Shank-90 Degree
I like knowing that I am going to produce the best product I can, using a quality tool. It's worth a few dollars more. It will last longer.

  • Excellent Customer Service
Pattern Name: Surfacing Bit Size: 1/4" Shank-1-1/2" Cut Dia. (2 Inserts)
I purchased this 1 1/2 inch spoil board surfacing bit out of curiosity, knowing 1/4 shaft may be a little small to sling that big of bit. I run a trim router on my CNC and so not high performance to start. The bit I got cut nicely in knotty alder but had a lot of vibration and was extremely loud. I reached out to the company asking a few questions and they replied back almost instantly. We exchanged question and answers and prior to me asking or them telling me I got notification they had refunded my money. I wondered if there was a factory issue and would gladly taken a replacement. I ended up taking the refund and purchasing a second identical bit to give it another try. I now know my trim router was most of the issue and contacted them again to let them know what I found and their first bit was fine, offering to pay for it because of the refund. They denied payment, thanked me for the update and hoped I continue to buy from them. Customer service like that now days is unheard of in my experience and this company has secured my business as long as I can use the consumables they offer. Thank you for being good to your customers. ... show more

  • BINSTAK CNC surface flattening router bit
Pattern Name: Surfacing Bit Size: 1/4" Shank-1-3/8" Cut Dia. (2+2 Inserts)
I purchase this bit to flatten a live edge piece of black want. It has not disappointed me and is still razor sharp. I'm pleased with its performance and value. Works as advertised and fit my Dewalt router great.

  • Works great to flatten - Use Conventional Cut
Pattern Name: Surfacing Bit Size: 1/4" Shank-1-3/8" Cut Dia. (2+2 Inserts)
The tool works very well. I found that if I climb cut it will leave witness lines in the wood. However, if I move the cut in the conventional direction it works great. It leaves no witness lines and is very smooth.

I'm a truck drive that has very little time to my hobbies and I've always wanted to flatten my own rough lumber and was able to, using this very bit.

  • Very high quality
Pattern Name: Surfacing Bit Size: 1/2" Shank-3" Cut Dia. (2+2 Inserts)
This works great for flattening hardwood slabs. Leaves a great finish. This is not for small routers or desk top CNC. I use a heavy duty router and will bog down if I push it too hard. I accidentally ran into my steel rails and it didn't hurt the bit at all but chewed into the rail. This will last a long time but would definitely buy again ... show more
