• HEAVY-DUTY HOLE MAKERS - Cuts sheet metal, metal plate, pipe, tubing and plastics up to 1/4” thick (sizes 5/16 - 3/4) or up to 1/2” thick (sizes above 3/4).
• SUPER FAST CUTTING - 3-5 times faster than drill bits or hole saws. Cuts a 5/8” diameter hole in 1/4” mild steel in as little as 20 seconds. Cuts a 1” diameter hole in 1/4” mild steel in less than 60 seconds.
• LONG LIFE - Lasts 300 times longer than hole saws.
• REDUCED EFFORT & FATIGUE - Requires only a fraction of the power and effort needed for drill bits.
• SUPERIOR CUTTING PERFORMANCE - Produces clean, burr-free holes without deforming the surrounding material.
• FAST HOLE-MAKING - Cuts around the hole, converting a smaller area to chips to allow much faster job completion.
• AUTOMATIC SLUG EJECTION - Automatically ejects the cut slug when the hole is completed.
• MASTER & EXPANDABLE SETS - Two sets are available; replacement components are also available individually.
• MADE IN THE U.S.A.

Note: Due to the extreme speed & aggressiveness of cut, Roto-Kut sizes larger than 1" are recommended for use in drill presses, not hand drills.
