Why Choose the 18mm Auger Bit for Fence Posts?
First and foremost, the 18mm diameter is the standard size for electric fence insulator holes in timber posts. Furthermore, the 460mm length provides deep reach for accurate, clean holes through thick posts. As a result, insulators seat firmly and securely without splitting the timber. In addition, the auger bit’s self-feeding tip reduces drilling effort and prevents wandering. According to the Australian Government Department of Agriculture, properly installed insulators are critical for effective electric fence performance.
Tips for Using Your Auger Bit
Before drilling, mark your insulator hole positions along the post at consistent heights. Then, drill at a slight downward angle to allow water to drain away from the hole. In addition, clear wood shavings regularly to prevent clogging. Finally, use a slow drill speed to maintain bit life and reduce heat build-up.
