Helical head for 8 inch jointers-details

#This helical cutter head is designed for the replacement of the G-8M cutter head. If your machine is younger than 2004, this cutter head will fit right. If the machine is prior to 1996, it uses a G-8 cutterhead, and you need to replace the pulley with a metric-sized pulley. If it is made from 1996 to 2004, you will need to measure the diameter of the diameter on end of the shaft on the pulley side to confirm. (G-8M head-19mm; G-8 head-3/4")
