**Q: Depth of cut, Inches per minute, chip load to place this cutter into the database Binstak can you provide information besides the rpm is a max. 16000**
A: I had great luck with this cutter on my home made slab flattening sled. The toughest part was sanding after flattening, so be patient while cutting, and sanding will be easier. I recommend cutting one direction only, 1/64” to 1/32” deep, and not more than about 1/4 to 1/3 of the cutter diameter per pass. More than those will leave the grain “pulled” in different different directions, especially if you’re cutting hardwood end grain. Patience on cutting will save a ton of sanding. Plus, too much rough sanding also can spoil the flatness. Finally, it makes one hell of a mess!  Best outdoors, with a vacuum hose jigged immediately in front of the cutter to catch the bulk of the sawdust jetting out ahead of the cutter. 
Patience!  Less is more!

**Q: Do you have 1 1/4 diameter?**
A: Dear customer, sorry, we don't have. we sell 1" , 2" and 3" diameter bit.

**Q: Does this come with the cutter heads?**
A: Dear customer, it comes with 1 set initial insert blades. We sell original inserts and screws. The parameter of insert is 12mm*12mm*1.5mm, 35 degree, straight hole. The type of screw is M4-6.

### ⭐⭐⭐⭐ Excellent Customer Service
*by M***E on May 15, 2022*

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.
