Review on Bosch Model Table Zero Clearance Insert by Gregory Braddock

This insert is much stronger than the standard Bosch insert for the 4100 series. If you wish it will be a very tight fit as it is slightly oversized and will need to be ground to fit your insert slot. You will also need to drill the slot for the riving knife BEFORE you start cutting the blade. You can use witness chalk if you're obsessed with accuracy, but the riving knife's cut doesn't have to be so narrow. Your zero clearance does its job at the front of the blade.
