Description of MAGBIT 701 0816 MAG701 2 Inch 8 Inch
High grade steel 1045 carbon steel for a longer life. Self feed tip has a single spur to leave a cleaner entry and exit hole. Quick change 7/16-Inch hex shank for use in quick change chucks or standard chucks. self feeding screw point for faster hole starts and easier cutting. Machined on a center post for a stronger more rigid bit.
Good quality bit but note the description for 1/2" bit is incorrect. It says it's a 7/16" shank, but it's actually a 5/16" shank. I will not work with large drills with Quik-Lok chucks.
Pros
Machined on center post for stronger and stiffer bit
