Description
Increment Borer History
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.
The continued history for Pressler’s invention goes in different directions. One story tells that the skilled craftsman Anders Mattson from Mora, Sweden, visited the exhibition in Paris and noticed the primitive Pressler increment borer on display. Mattson bought the instrument at a cheap price with the intentions of transforming it to an instrument that could be used in and by an upcoming forestry industry. Another story tells that Mattson in Mora was contacted by toolmaker Anders Nilsson, who allegedly asked Mattson to manufacture an increment borer. Facts support both stories: at the historic forestry museum of Siljansfors Mora, Dalecarlia, Sweden, an antique borer marked A. Nilsson, Mora is displayed along with another, as old borer, marked And. Mattson. Both borers are produced in the 1890ies.
Anders Mattson owned the company Mattsons Mekaniska Verkstads AB together with his brothers. One of the brothers, Jannes Mattson, started his own company called Beus & Mattson, in 1895. Beus & Mattson started a manufacturing of increment borers named of Djos.
August Haglöf was an employee at Anders Mattson. Haglöf refined the borer and after his death in 1936, August’s sons, Anders and Erik, took over where he left off. Later on, the Haglöf brothers quit their employments at Mattson AB and started Haglöfs Mek. Verkstad i Mora AB.
In 1968, Beus o Mattson had changed their name to Djos and the borer production moved to Finland. 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. The Haglöf borer brands picked up market shares and in 1981, the American daughter office Haglof Inc opened up in Mississippi, USA. Haglöf increment borers would soon become the leading brand in North America.
One of the most important tools for a dendrochronologist is the increment borer.
Mattson borer
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 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.
Djos borer
In 2010, the classic Djos borer brand was incorporated to the Haglöf Sweden increment borer manufacturing. The Djos borer handles are orange and the borer bit has a special back-threading, preferred by many operators when backing out of the tree.
Djos borers are manufactured in selected lengths and as 3-threaded borers. See separate leaflet for details on the Djos borers.
