0.62" Forstner Drill Bit,Hex Shank Carbide Tipped Wood Drilling Wood Tool Punching Bit(16mm)

This Forstner bit embodies the design typical of the least-expensive types - with carbide elements in critical cutting areas fused to lower-cost steel for the remaining bulk of its composition. I have used it only in a drill press for drilling into/through basic softwood 2x4s. It did that successfully, but only with care, going slowly and backing out several times because it doesn't clear the removed wood very well. The slow speed required leaves it prone to burning around the perimeter of the hole; I didn't support the 2x4s with a backing sheet, so there was also a minor amount of tearout when going through completely. In short, it worked for what I needed, and met my limited going-in expectations - for a bit of this size at its cost. More precise or higher-demand applications (including harder wood) would likely require a better bit at higher cost (especially for this relatively large diameter).
