The Steel Dragon Tools® 13-piece high-speed steel annular cutter kit includes 11 annular bits and two (2) pilot pins. These bits will quickly and safely cut holes in steel. The bits have a 1-inch cutting depth with a 3/4-inch Weldon shank. Bit sizes included: 7/16 in., 1/2 in., 9/16 in., 5/8 in., 11/16 in., 3/4 in., 13/16 in., 7/8 in., 15/16 in., 1 in., and 1-1/16 in.
Features:
- Steel Dragon Tools® annular cutters will drill large holes up to ten times faster than regular drills bits.
 - Machine-finish hole with no reaming needed when using lubricant.
 - Make overlapping holes, slotting holes, and edge cuts.
 - Bit size is etched on each cutter.
 - Pilot pin helps locate center of hole location.
 - Pilot pin helps eject slug after drilling is complete.
 - During the drilling process, the pilot pin will retract into the cutter allowing lubrication to reduce heat gain in the slug.
