Milwaukee Magnetic Drill Bit Set 14-24 mm, Length 30 mm, 6-Piece

100% Faster. The factors described below play a role in achieving speed and time savings. The principle of the annular cutter involves removing material only from the outline of the hole, as opposed to a twist drill, which has to cut across the entire diameter of the hole. Another advantage is the two powerful sharp corners for each cutting edge to accelerate feed and reduce cutting resistance.
30% Higher Productivity. Productivity is higher because the annular cutter cuts material only from the outline of the hole. Less motor energy and operating force are required. The larger the drill diameter, the greater the energy savings.
Longer Usage Time. The cutting edges of annular cutters do less work than a twist drill, resulting in more holes between sharpenings. A 6 mm thick working part with special tooth geometry ensures high stability and minimizes the risk of breakage due to overload.
Thick-walled HSS drills for greater durability and longer working life.
Standard 19 mm Weldon attachment.
Cutting depth 30 mm.
