When drilling, the drilled holes must not be repeated again. Otherwise, the drilled holes cannot be rounded, and the inside of the drilled holes will be blocked by paper scraps. * 2. Reasons for the blockage of punch drills: Papers are not tidy and uneven; gaskets are not put in right place or lubrication are not enough etc.; punched papers cannot be punched repeatedly; If the drilling size is small, the pressing rod speed should be slower; the drilling time is too long; the thickness of the drilling paper is too thick. * 3. Please wear work clothes and protective glasses to prevent the skin and eyes from being injured. Heat is generated during the drilling process. When the product is rotating, it is strictly prohibited to touch it by hand. * 4. Straight shank (H): Installed on the machine with screws (need to be screwed). Easy to disassemble. Wide Applications * Widely used in punching tags, photo albums, wall & desk calendars, account books, and handbags. Suitable for ordinary paper, offset paper, coated paper, grease film paper, leather, fabric etc. * The stacking thickness of the offset paper should be 80% of the punching thickness, 60% for base paper, 40% or less for grease film or glazing paper. For example: drill bit with 6mm punching diameter and 50mm punching length (thickness). The total thickness of offset paper to be drilled should be 40mm; the master paper or base paper should be 30mm; and the film or glazing paper should be less than 20mm.
