Milwaukee 4932371749 HSSAC annular cutter 40 × 30 mm, 19 mm Weldon

Milwaukee 4932371749 HSSAC annular cutter 40 × 30 mm, 19 mm Weldon. HSS annular cutter, 40 mm diameter with 30 mm cutting depth and standard 19 mm Weldon shank. Removes material only around the hole circumference, unlike a twist drill cutting the entire cross-section. Two sharp angles on each cutting edge support feed and reduce cutting resistance. Less material removal reduces motor power and operating force requirements. Thick-wall HSS construction and special tooth geometry support stability and durability; the supplied manufacturer description specifies a 6 mm working-section thickness. Reduced cutting-edge workload helps extend intervals between sharpening.
