Well built, versatile and durable, this 1-3/8" x 2" Annular Cutter (49-59-2138) from Milwaukee. The double bevel and flat teeth cut more aggressively and boost chip ejection, while the thinner wall construction displaces less material for 15% faster cutting. The proprietary steel reduces breakage and extends bit life for long lasting use. Plus, it's impressively versatile: one centering and ejecting pin size works for all 2" depth cutters.
