Designed specifically for use with Hougen's "12,000-Series" annular cutters, this pilot tool is essential for achieving precision in hole cutting applications. With a depth of 1 inch, it is compatible with cutters ranging from 7/16" to 9/16" in diameter, ensuring optimal alignment and functionality. The pilot serves three crucial purposes: it aligns the cutter with the center of the hole, facilitates coolant flow to the cutting teeth for enhanced performance, and efficiently ejects the slug at the end of the cut. This tool is a reliable addition to any toolkit, enhancing both the efficiency and effectiveness of your cutting tasks.
