3/4-Inch High-Carbon Steel Forstner Bit
This 3/4" bit is part of a line of imported Forstner bits that Woodcraft has tested and found to cut clean and not burn even when testers intentionally subjected them to quick, repetitive drill press borings. An exceptional value for the hobbyist or occasional user. 3/8" shankFeatures:...
• 3/4" Forstner bit
• Cuts clean; no burning when subjected to harsh treatment

I bought the Woodriver and Freud Precision Shear Forstner bits to compare. The Freud bit is far superior in drilling a hole way more than twice as fast. The Woodriver got very hot while only drilling a 1/3 of the way through a 3/4-inch maple board, while the Freud drilled the full depth and was only warm. The Woodriver bit had all the edges ding and dull, whereas all the Freud edges were crisp and sharp (would easily cut you, take care). At a cost difference of only $3, it is not worth my time or wearing out my stones to repair the Woodriver edges. Dings take a fair amount of grinding to remove. Also, the chipper relief angle seemed shallow (considerably lower than Freud's). Increasing the chipper angle might improve cutting speed, but would require a fair amount of work.
