I've been using it with a variable speed drill and the hole is perfect! No need to use a drill press. The hole is .15mm bigger than 20mm. I am using it to create a MFT style work surface.

This Forstner bit is extremely sharp and it produces very clean and accurate holes. No complaints so far. Drilled red oak and some teak with no dulling that I can tell.Honestly, most Forstner bit problems in online reviews stem from improper drill speed or use in a hand held drill. Forstner bits are really designed for use in a drill press at relatively low speeds.This bit is an excellent value for money especially when used properly.
