The Harris Micro-Punch® consists of a razor sharp cutting tip designed to cut, retrieve cored samples from source materials such as tissue, gels, paper, cloth, leaves, paint chips, films or other thin substrates.

It's ideal for tissue processing or forensic applications. Tips are machined from 440c stainless steel that is heat treated to Rockwell Rc 58 hardness and then individually sharpened to a razor edge for a long cutting life. Tips are available in diameters ranging from 0.50 to 3.00mm. Stock sizes: 0.50, 1.00, 1.20, 2.00 and 3.00mm. The plungers consist of a knob-screw assembly made from injected molded, high tech, lubricated plastic to eliminate sticking with a 440c stainless steel ejection rod and spring. Each Harris Micro-Punch® is sold with a protective plastic tip cover and a 6" x 8", 1.5 mm thick, inert, self-healing Harris cutting mat with dual cutting surfaces. Replacement tips, ejection rods and mats can be ordered separately.
