Replaceable-Tip Drill: 10.5 to 10.99 mm Dia, 54.86 mm Max Depth, 11.11 mm Straight-Cylindrical Shank MPN:2250679

Through-hole laps with a diameter of one inch and length of eight and half inches are ideal for polishing small cylindrical surfaces or bores which require a precise surface finish like aerospace industry's engine piston rings or precision molds in the plastic injection molding industry. The through-hole lap provides a smoother surface than other manual polishing methods resulting in less friction and longer-lasting products reducing maintenance costs for industries such as automotive and aviation. It is cost-effective compared to grinding, laps result in better consistency, improved parallelism tolerance plus the tool's ability to accommodate intricate shapes in internal diameters providing a faster process improving overall productivity resulting from its efficiency. The industries which heavily rely on precision surface finishing of small cylindrical components like aerospace, mold making for plastics and metallurgy would benefit considerably from this tool.
