Annular Cutter Set, 5-Piece HSS 1/2 in Weldon Shank

Annular cutter set for magnetic drills delivers fast, clean holes with less burr and chip buildup, helping you finish steelwork with fewer tool changes. Built from M2AL high-speed steel for wear and heat resistance, this 5-piece kit covers common maintenance and fabrication drilling tasks. The 3/4" Weldon shank fits most mag drill clamps, while the annular cutting design removes only the material you need for efficient cutting and smoother operation.

• Includes 3 annular cutters (1/2" dia) plus 2 pilot pins and 3 storage cases for organized transport.


• Delivers 1" cutting depth for through-holes in plate and structural steel with a single bit.


• Fits most magnetic drills using a standard 3/4" Weldon shank for quick install and removal.


• Reduces chip packing with enlarged chip slots that support smoother chip flow.


• Handles metalworking in steel, stainless, aluminum, cast iron, and copper for jobsite versatility.

When downtime costs time and accuracy matters, this annular cutter set keeps your workflow moving with dependable fitment and efficient cutting geometry. Use the pilot pins to improve centering and support consistent slug ejection during drilling. Keep the cutters protected between jobs with the included cases, and stock your mag drill kit with the sizes you reach for most in fabrication, maintenance, bridge and rail work, and general metal construction.
