Designed specifically for use with Hougen's "12,000-Series" annular cutters, this pilot tool is essential for precision hole cutting in materials with diameters ranging from 7/16" to 9/16" (12 - 15mm). With a depth of 2", it not only ensures accurate alignment of the cutter with the center of the hole but also facilitates coolant flow to the cutting teeth, enhancing the cutting process. Additionally, it efficiently ejects the slug at the end of the cut, making it a versatile and indispensable tool for any professional or DIY enthusiast engaged in hole cutting applications.
