Fein 6 31 34 191 04 1 3/4″ x 1″ HSS Annular Cutter, 3/4″ Straight Shank

The Fein Slugger 3/4″ x 1″ HSS Annular Cutter delivers fast, clean, and precise hole cutting in steel, aluminum, and non-ferrous metals. Built from M2 High-Speed Steel and manufactured in the USA, this cutter is optimized for performance and long service life. It features a 1″ cutting depth and comes equipped with a 3/4″ Weldon straight shank, making it fully compatible with most magnetic drill presses on the market. Designed with coolant-fed cutting edges and re-sharpenable teeth, this cutter helps reduce heat build-up while maintaining sharpness through repeated use.

The included pilot pin allows for easier hole positioning and solid slug ejection, reducing material waste and ensuring cleaner finishes. With precision-ground geometry and CNC-manufactured tolerances, it’s a reliable tool for industrial, on-site, and fabrication work where speed, accuracy, and repeatability matter most.

Why Professionals Choose the Fein 3/4″ x 1″ HSS Annular Cutter, 3/4″ Straight Shank

Often called a slugger bit or mag drill cutter, this 3/4″ annular cutter is known for drilling fast and leaving a clean, burr-free hole behind. Instead of grinding through with a twist bit, this tool cuts only the outer edge, forming a clean slug and reducing heat and tool strain. It’s perfect for pros who want dependable performance without time-wasting setups. Whether you’re drilling into a bracket in the shop or boring through I-beam flanges in the field, this bit gets it done with fewer steps, faster results, and less wear on your gear.
