Haglof Increment Borers Haglof Sweden manufactures the world’s largest assortment of increment borer brands, models and sizes. Haglof Sweden increment borers have blue handles in grip friendly plastic material and a metallic lock. The borer bits are made from hardened steel with PTFE-coating for protection and reduced friction. The extractors are produced in stainless steel with metallic head and special shaped tip for easy extraction of the wood core. • LENGTHS are available from 100mm or 4" up to 1000mm or 39". To obtain optimal penetration depth, the borer bit should be approximately half to three quarter of the tree diameter. • CORE DIAMETERS: Haglof standard core diameters are 4.3 mm and 5.15 mm (0.169" and 0.200"). 10 and 12 mm diameter borers are available in assorted lengths. These borers are often used to measure wood fibre lengths and quantitative analyses where large samples are necessary. • THREADING: Most Haglof borers are available with either 2- or 3-threads on the borer bit. 2-threaded borers are suitable for hardwood as they penetrate the tree with less friction. 3-threaded borers engage the wood faster. 3-threaded borers are the most common threading option. • SPECIAL coating is available for selected borer bits in lengths 100mm/4" 150mm/6" 200mm/8" and 250mm/10". • A COMPLETE increment borer includes handle, borer bit and extractor in selected length and model. Borer bits and extractors can be purchased separately. Haglof Sweden borers are optimized for growth and quality control in trees and used in management, planning and for scientific studies, such as: • Average age of a stand or exact age of individual trees • Forest health and to predict future growth • Calculate site index of a stand • Environmental control, soil fertility and fertilization effects • Disease, insect attacks, and the structural condition of the tree • Quality control by examining wood density • Control of the environment outside the tree, such as water and soil quality through laboratory analysis of the tree core • Chemical studies to determine suitability for different purposes and to check impregnation depth When boring a tree, the core sample and bit should be removed from the tree as soon as possible. The tree instantly starts a process to close the hole in the stem. The wood will expand if left inside the borer bit. Clean your borer, and especially the threading of the borer bit and the extractor regularly, and preferably after each working day. Use thin oil to clean and a clean tissue or rag. Be careful since the edges are sharp. • Never store your increment borer wet and dirty. • Never drill with the extractor inserted in the borer bit. The extractor should be inserted when you are ready with the drilling. • If you suspect that a tree may contain nails or other metallic parts, if the tree is rotten, decayed or contains dead wood, it is recommended not to use the increment borer in this tree. • Apply some beeswax on the borer bit tip for next use - this can improve and make the drilling easier. Do not attempt to extend the borer handle with a stick or other tools, or to use a drilling machine or other equipment together with the increment borer or parts of it. Doing so will make all product warranties void. Increment borers are precision instruments and crafted for manual operation. The borer is adjusted to fit exactly in its handle and extractor, with all proportions optimized for this purpose.
