Greenlee 628 Carbide Annular Cutter Set 11 Piece

Product Description

The GREENLEE 628 is an 11-piece carbide annular cutter set designed for fast, clean hole cutting in steel, aluminum, and other metals. Annular cutters remove only a thin ring of material rather than the full disk, reducing cutting force and extending tool life compared to standard twist drills or knockout punches. This set covers a cutting diameter range of 7/8 inches to 2-1/2 inches with a cutting depth of 0.187 inches. An oxide finish protects the cutter bodies from corrosion during storage and use. The set is suited for electricians, HVAC installers, and metalworkers who routinely cut conduit knockouts or access holes in enclosures and panels.

This cutter set is appropriate for use in residential and commercial electrical, HVAC, and mechanical applications where precise, burr-minimal holes are needed in sheet metal, electrical enclosures, junction boxes, and structural steel. The range of 11 cutter sizes in a single kit makes it practical for service technicians who need to carry multiple sizes on one job without sourcing individual cutters separately.

Installation Notes

Annular cutter sets should be installed and operated by qualified electricians or metalworkers familiar with rotary cutting tools and associated safety practices. Ensure the workpiece is firmly secured and that any nearby energized components are de-energized and locked out before cutting. Use cutting fluid or lubricant to prolong cutter life and reduce heat buildup during operation. Follow applicable NEC guidelines when cutting knockouts in electrical enclosures.
