What do I need to know about increment borers?
Basic knowledge of an increment bor- er includes knowing: the proper length and core diameter required when purchasing an increment borer; where on the tree to core and how to properly start a borer; how to determine whether a borer is jamming
What is increment boring in trees?
INCREMENT BORERS Increment boring causes injury that is compart- mentalized by the living tree. Compartmentaliza - tion is a boundary- setting process that resists the spread of cell death and infection by microorgan- isms (Shigo 1985; Smith and Sutherland 2001). In healthy, vigorous trees, these boundaries form on
How do you use an increment borer auger?
Continue to apply in- ward pressure and rotate the increment borer as much as possible. Repeat this procedure until the threads engage and the auger tip enters the tree. The auger handle can be turned with both hands using either half -turns (better for hardwoods) or full -turns (better and faster for conifers).
What are increment borer extractors made of?
The extractors are produced in stainless steel with metallic head and special design for easy core extraction of the wood core. . Haglöf Sweden produces the world’s largest assortment of increment borer brands, models and sizes.
How do you age a tree with increment borer?
In order to determine the age of a tree without killing it you need to use a tool called an increment borer. Using the increment borer you get a cylinder of wood that goes from the bark of the tree to the core. You can count the rings on the cylinder to determine the age of the tree.
What is a tree increment borer?
An increment borer is a specialized tool used to extract a section of wood tissue from a living tree with relatively minor injury to the plant itself.
Who invented the increment borer?
Max Pressler... increment borer device was developed by Max Pressler (1815-1886) in the mid- nineteenth century (see Figure 3). As a forester (as well as an economist and inventor) he intended its use for silvicultural growth analysis and assessment of forest crop trees. ...
What is increment instrument?
Details. The increment borer is the classic instrument for fast and reliable results when controlling age, increment growth and soundness of trees. Increment borers are also used for decay check-up, pollution control, wood density, chemical penetration control etc.
How do you clean increment borers?
Keep your borer clean and sharp at all times! Any type of light oil can be used, sprayed directly into the borer bit and wiped with the tissue. Caution! The cutting edge is sharp and to avoid injury, wrap the tissue around for example the extractor tip, when cleaning. Steel wool can be used to remove rust.

How do you determine the age of a tree without cutting it down?
The girth of a tree can be used to estimate its age, as roughly a tree will increase it's girth by 2.5cm in a year. So, simply measure around the trunk of the tree (the girth) at about 1m from the ground. Make sure you measure to the nearest centimetre. Then divide the girth by 2.5 to give an age in years.

When was the increment borer invented?
Increment borers have a long history dating back to The World Expo in Paris 1889. The German inventor’s last name Pressler is sometimes still used as a synonymous word to increment borer. Other names are Mora borer, tree borer or Haglöf borer.
What is Haglöf borers made of?
Haglöf 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.
When did Haglöf buy Mattson Borers?
In 1992 , Haglöf Sweden purchased the original And. Mattson borer brand, along with a borer stock and production machinery. Instead of closing down this traditional precision instrument, we decided to continue and develop the production. The Mattson borers maintain their brand specifics and are available in assorted lengths and dimensions. Mattson borer have a non-coated polished steel finish and brass details on handle and extractor. If you are looking for small core diameter borer, Mattson borer no 10-200-1001 is available with 200 mm length and 3.5mm core diameter. The classic Mattson borer ”no 905” is a best seller designed to withstand tough hardwood.
Where are Djos borers made?
The Djos borers were produced and marketed under the name Suunto. Some of the production equipment and the brand Djos was accredited to Haglöfs Mekaniska. In the early 1970ies, Ingvar Haglöf took over his family business and the increment borer production and moved it to the northern parts of Sweden.
What is the difference between a 2-threaded and 3-threaded borer?
2-threaded borers are recommended when drilling in hardwood, with a slower penetration in the wood and less friction and stress onto the material. 3-threaded borers will penetrate the wood faster and is suitable for most types of wood.
Where is the Tree Ring Lab?
Ingvar Haglöf, former CEO and founder of Haglöf Sweden, was in 2013 honored with a unique gift from the Tree Ring Lab: a section from a 3500 year old Bristle Cone-pine with the annual rings clearly visible. Haglöf Sweden had in turn the pleasure of presenting a custom made board to the Tree Ring Lab at the inauguration of their brand new laboratory building. The board contained some of the ancient industrial history concerning increment borers, as well as some antique borers.
What is an increment borer?
Increment borers are tidy instruments that consist of a handle (that serves double duty as a case), a bit and an extractor. (Figure 4.7). The bit is locked onto the handle, making a “T”-shaped instrument, then twisted into the tree (Figure 4.8). Once the bit has reached a little more than half-way through the trunk’s diameter, the extractor, a thin metal sleeve, is used to retrieve the core sample as described in the next section, “ Field Techniques for Increment Boring .”
How to determine a tree's age?
An instrument called an increment borer extracts a small, pencil-sized piece of wood, or core sample, from the trunk of the tree. A mini-auger is drilled by hand from the bark to the center (pith) of the tree. The resulting core sample extracted from the hole displays the tree’s annual rings (or increments of growth) at that point in the tree (Figure 4.6). The tree then “pitches” the hole over, filling the small cavity with resin.
Do you have to cut away brush to use a tree borer?
(At the base of the tree, one would constantly hit the ground or roots of the tree.) Brush and other vegetation do not have to be cut away in order to operate the borer. There is generally room to avoid oddities in the tree’s trunk – branch whorls, cankers, etc.
Do trees have rings?
Ring counts are not foolproof! For example, many tropical trees and diffuse-porous hardwoods have annual rings that are nearly indistinguishable. Trees may also produce “false rings” during years of unusual weather conditions (e.g. drought followed by high rain, lammas years), or indistinct (missing) rings in years of extreme drought or defoliation. The older the tree, the more opportunities there are for abnormalities. Therefore, it is important to remember that core samples provide only estimates of tree age.
What is an increment borer?
An increment borer is the primary tool used to collect samples for dendrochronological analyses. These are precision instruments and users should be trained in their proper use, care, and maintenance. In this paper, I describe the various parts of an increment borer and how to keep these in working condition. I provide details on how to sharpen an increment borer, properly core a tree, check for core compression ( "jamming "), extract the core, and store the core for transport. I provide tips on how to clear a jammed borer and remove a borer stuck in a tree. An important topic concerns the effects of boring on trees. The majority of studies indicate that conifers are minimally affected by both fungal decay and discoloration, whereas certain hardwood species can sustain major internal damage. Plugging the holes created by coring is unnecessary. Keywords: increment borers, increment borer maintenance, damage from increment borers, field methods.
Where was the increment borer invented?
INTRODUCTION The increment borer was developed in Germany
Why should the tip of an auger be sharpened?
The tip of the extractor should also be kept sharpened to ensure it slides smoothly under the core upon insertion. When
Why should you put a Teflon auger in the handle?
storing or transporting, the auger should be care- fully and slowly inserted into the handle to prevent excessive contact with the threads of the handle. This ensures the threaded tip of the auger and the threads inside the handle stay sharp. To ensure the auger surface stays smooth, coarse abrasive paper should not be used on its exterior during cleaning. The Teflon® coating, however, will wear off slow-
How long should a borer be for a tree?
mm (39 in.) can be specially ordered. The length required for a particular study should be carefully evaluated before purchasing. For example, if soft- wood trees less than 300 mm (12 in.) in diameter are to be studied, you should purchase a 350 mm (14 in.) borer. This will allow you to core straight through the tree and obtain a core that represents the complete diameter of the tree.
What is required to turn the larger di-di-di?

Why is my wood core ragged?
wood cells rather than slicing them cleanly, caus- ing the core to appear ragged. A dull tip will also cause more friction upon the core, causing break- age, twisting, and possible "jamming" inside the borer. "Jamming" occurs when the outer wood on
