Description
The increment borer is a classic instrument for fast and reliable results when evaluating age, increment and soundness of trees. Increment borers are also used for decay check-up, pollution control, wood density, chemical penetration control etc.
Haglöf increment borers are available in a wide variety of sizes, lengths, models, variants and core diameters for all types of wood and trees. Haglöf borers are produced with high quality steel with PTFE one-coat on the borer bit to protect against rust and resin and to reduce friction.
The solid Haglöf borer bit with a barrel shaped tip ensures an easy start and removal from the tree. The extractor is made with stainless steel and metal knobs. The many options of sizes and models of our Haglöf Sweden increment borers guarantee the exact right borer for each specific application.

Length
Borers are available from 100 mm or 4” up to 1000 mm or 39”.
For optimal penetration depth, the borer bit should be approximately one half to three quarters of the tree’s diameter.
Core Diameter
Standard core diameters are 4.3 mm or 5.15 mm (0.169” and 0.200”).
10 and 12 mm diameter borers are available in assorted lengths and are mainly used for quantitative analyses where large samples are necessary.
Threading
Borers are available as either 2 or 3-threaed borer bit. 2-threaded borers are recommended for hardwood. 3-threaded borers are the most popular, since they will be easier to work with and engage faster in the wood.
Borer tip
The borer tip with thread has an unique convex arc-shape to easily penetrate and cut the tree fibre.
Coating
The increment borer bits are treated and protected with PTFE-coating which reduces friction and protects against corrosion.
Extractor
The extractors are made of stainless steel and designed to extra easily pull out wooden cores.
Complete increment borer
A complete increment borer includes the handle, a borer bit and an extractor in selected length and model. Borer bits and extractors can be purchased separately.
