Haglöf Increment Borers

• 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
• 5.15mm diameter
• 200mm, 300mm, 400mm, 500 and 600mm lengths
• 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
