Haglof Increment Borers:

All Haglof Borers feature a cutting tip that reduces chipping and loss of shape. Easily retrieves core samples from trees and wood to determine growth rate, age, tree soundness, and other necessary information. Tough Teflon® coating reduces friction and resists rust and resin build-up, allowing for easier boring and longer bit life.

About Increment Borers :

• Increment borers are used to extract core samples from trees and treated wood products.
• They allow determination of growth rate, tree age,
  tree soundness and the penetration of chemical treatments.
• Borer length is measured from the tip to the end of the round section of the bit and represents the maximum depth of penetration.
• Replacement parts are specific to the brand of borer. They are not interchangeable with other brands.
• The inside diameter of the opening at the treaded end of the bit determines the diameter of the core sample. Both .169″ and .200″ are commonly used for forestry. .500″ is available by special order.
• A three-thread borer has three threads on the cutting edge while a two-thread borer has two threads on the cutting edge. A three-thread borer will penetrate deeper per revolution than a two-thread Borer. Choosing between the two is a matter of personal preference.
