## Questions & Answers

A: Hello dear customer, very glad to tell you that we started selling original blades, this is the product link:

**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.
