The N1R Hand Notcher makes a clean 30 deg V shaped cut in 24-gauge (0.71 mm) galvanized steel. Maximum throat depth is 13/16 in (20.66 mm). Upper cutting jaw is drop forged high impact alloy steel. Hook design of cutting jaw facilitates notching corners or take-off tabs to desired depth without slipping. Long-wearing cutting jaw and hardened stamped steel components feature rust resistant nickel plate and black oxide finishes. The N1R Notcher also features ergonomic Redline Handle technology. An Engineered handle opening compliments the natural power stroke of any user's hand and maximizes the powerful 7:1 mechanical advantage of compound-leverage head to handle linkage. Comfortable handle grip contours, a non-slip grip insert, spring handle actuation and a thumb-operated handle latch ensure a natural fit and feel for comfortable one hand operation anywhere on the job.
