Where are the specs on the bit? A history of the company doesnt help me decide if this bit meets what i am looking for?

Please complain to Amazon about the description - they have the complete description but their algorithms thinks this is better because it has more words. 🙄. This bit is 1/4" diameter x 1" cutting length x 1/4" shank x 2-1/2" long - upshear. For a complete description of any Whiteside product and a picture, please visit our eoasaw website. Please advise how we may be of assistance. Thanks Thom

will this bit cut a 1/4" recess in a 3/4" red oak board? the recess has to be 3" x 4".

This is my bit of choice. This bit makes a good clean cut. So you are cutting a 3" x 4" 0.25" deep?

does this bit cut acrylic like Plexiglas and leave a good edge?

This bit will cut acrylic, however a o-flute bit would be better suited. Any bit you use will probably still leave some visible signs of cutting, the edge can then be polished or some people use a torch to smooth the finish. The key is getting the correct chipload and making sure the part is held firmly. You are welcome to download my free CNC manual and chipload calculator from the technical section of our eoasaw website - the principles apply to any cutting situation. Please advise how I may be of further assistance. Thanks, Thom
