Annular Cutter Set, 16-Piece HSS 3/4 in Weldon Shank

Annular cutter set delivers fast, clean holes in metal with less effort than twist drilling, helping you keep production moving. This 16-piece kit includes 14 M2AL high-speed steel annular cutters plus pilot pins, built for stable starts and smoother chip evacuation. The 3/4" Weldon shank fits most magnetic drills, making it a practical choice for steel fabrication, structural work, and on-site installs.

• Delivers clean, efficient cutting with an annular design that removes only the material needed.


• Includes 14 cutter sizes to cover common hole diameters for fabrication and maintenance work.


• Fits most magnetic drills using a standard 3/4" Weldon shank for quick tool changes.


• Supports smooth chip flow with enlarged chip slots to reduce buildup during drilling.


• Stores securely in a plastic case to keep cutters and pilot pins organized between jobs.

Built for metalworking where accuracy and uptime matter, these mag drill bits are suited to structural steel, stainless steel, aluminum, cast iron, and copper. Flat/pointed blade geometry helps guide entry for steadier starts, while heat- and wear-resistant HSS supports longer service life in demanding environments. Use them for bridge and rail work, shipbuilding, steel structures, and general metal fabrication. Grab yours today and keep the right sizes ready for the next job.
