Haglof Increment Borer 200mm 3-thread

Description

High quality Swedish made increment borers to extract cores of wood from trees to determine growth rate, age, chemical penetration and soundness. Teflon coated bit reduces friction and protects against rust and resin build-up. Available in 2-thread or 3-thread. We strongly recommend using 2-thread borers for Australian hardwoods and 3-thread borers for softwoods – 2-thread borers provide easier penetration in tough timbers. 200mm, 5.15mm diameter, 3-thread
