Greenlee Expands its Carbide Cutter Sets with More Cutting Sizes

Rockford, IL -- Greenlee Textron, a Textron Inc. (NYSE: TXT) company has launched the new 628 and 648 Carbide Cutter sets, each with 6 cutter sizes ranging from 7/8-inch to 2-1/2-inch, to better meet the needs of electricians, plumbers and other trade technicians.  The complete product family offers 22 sizes ranging from 5/8-inch to 3-inch.

“These new sets make it more convenient for our customers,” said Rob Bentley, Greenlee Product Manager. “Greenlee’s Carbide Hole Cutters are known as a durable solution for drilling in stainless steel and other materials, and now we offer two solutions for ½-inch to 2-inch conduit-sized applications.”

Greenlee’s Carbide Cutters cut fast, accurate holes in stainless steel, mild steel, iron, copper, brass, aluminum, fiberglass and plastic sheet up to 3/16-inch (4.8mm) thick.  The split-point, cobalt-steel pilot drill eliminates walking and penetrates quickly.  Precision engineered, tungsten-carbide teeth allow for fast cutting of round, burr-free holes.

Greenlee’s carbide design is optimized to reduce friction and torque, requiring less force and generating less heat while cutting.  This allows the cutters to last up to five times longer than many competitive cutters.  There is a flange stop that helps prevent over-drilling for added safety, and an ejector spring that automatically removes the slug with every cut.

The 628 Carbide Cutter set features a built-in arbor on each cutter, while the 648 set includes separate Cutters and two Quick Change Arbors, allowing the user to reduce costs by replacing cutter sizes without having to replace the arbor.

The new Carbide Cutter sets are an innovative solution for Faster, Safer & Easier® HoleMaking from Greenlee. For more information, visit or call 1-800-435-0786.
