CNC Spoilboard Surfacing Router Bits, 1/2 inch Shank 2 inch Cutting Diameter, Slab Flattening Router Bit Planing Bit Wood Milling Cutter Planer Woodworking Tool by BINSTAK (Carbide)

I leveled a solid white oak slab and this not only worked fast, it left a fantastic finish that made sanding a snap.Great price and works excellent. Highly recommended

The 1/2 shank gives much better performance and smoother surfaces than the 1/4 shank tool I used before for the same applicaton. The larger cutting surfaces also "burn" less when machining large areas. It works well even on highly figured wood surfaces.

I've used this bit and few times now on an epoxy project and a piece of ironwood and it seems to be holding up great! I get just a little bit of swirling in the epoxy flattening but that may be my own error in going too fast. I'm happy with the purchase.

I used this the plane an end grain cutting board. Bit feels sharp and high quality. I made many passes over hardwood and didn't notice the blades dulling at all. No burning or tear out. Bit is a good size to take a decent path of material as long as you don't go too deep.

I was hesitant about purchasing such a cheap router bit. I am flattening a 8 inch thick hardwood crosscut slab to make a coffee table.This bit was so affordable for what is probably a one project use. It worked very well. I cut the slab down 2 inches to 6 inches and may even go a bit thinner. The bit did very well in my big Bosch router with the router bit extension I bought with the bit. The bit cuts well up to almost 1/4 inch per pass. I didn’t try to go any deeper.The finished cut surfaces is dead on flat but will definitely need sanding . I expected that. Not sure how much better a expensive router planner bit cuts and finishes, but sandpaper is cheap.This is a good deal for a big planer bit.I have no idea how long this bit will last but looks great so far after multiple passes through hardwoods.

Excellent durability

Sharp right out of the box. Got this to use in a router jig for flattening boards and so far it is working good.

I have several wide (28"+) Walnut slabs I used to flatten these with a belt sander and manual planes. This bit provides a flat surface which requires only a little sanding to prep it for use. Using a 1.75 HP Porter-Cable router and monitoring the depth of cut leaves a flat slab quickly. Think 1/4 the time of flattening by hand. Based on the results with Walnut i fully expect that this bit will work equally on Cherry, Purpleheart, Oak, Birch, Maple and other commercially available hardwoods. I am not certain about Poplar. It tends to be a 'stringy' wood.My preference is to cut no deeper than 1/8". Similar to my Planer. The carbide cutters on this bit are visually the same as other router bits I own. Care must be used when using a flattening jig and bridge. Feed the router at a pace the bit wants to set. Do not stop in the middle of cuts in wood that is given to burning. Oak and Cherry are known for this.This is a good bit and it is priced to be disposable when dulled. It should be good for at least three of my slabs. 30" wide by 9.5' long.
