9 sold in last 24 hours
- Accurate Wood Sampling: Designed for extracting core samples from trees, treated poles, lumber, and timbers to assess growth rate, age, internal condition, and chemical penetration.
- Large Core Diameter: 0.200" (5.15mm) core size ideal for qualitative analysis and larger sample needs.
- 12" Bit Length: Suitable for medium to large trees, offering a maximum penetration depth of 12 inches.
- 2-Thread Design: Features two cutting threads originating 180° apart for controlled penetration and consistent performance.
- Durable & Efficient: Teflon-coated Swedish steel bit resists rust and resin build-up, reduces friction, and extends tool life.
- Versatile Forestry Tool: Trusted by professionals for general forestry and wood preservation applications.
- User Consideration: Penetration ease depends on wood hardness, friction, and user strength.

Teflon coating protects bit against rust and resin build-up and reduces friction. How to select the correct Increment Borer for your needs. Three factors to consider when ordering an increment borer are bit length, core diameter and thread style. Borer Bit Length depends on the size of the trees you will be boring. Length is measured from the tip of the threads to the end of the round section of the borer bit. This is the maximum depth the bit will penetrate. Core Diameter of the wood sample is determined by the inside diameter of the opening at the threaded end of the bit. 0.169” is commonly used for general forestry use, 0.200” for wood preserving testing and 0.500” for large amounts of wood for qualitative analysis. 2- or 3-Thread style is a matter of personal preference. A 2-thread borer has two threads on the cutting edge of the bit, each originating 180° apart. A 3-thread borer has three threads, each originating 120° apart. The higher thread pitch of the 3-thread borer will penetrate deeper per revolution than a 2-thread. A 3-thread will also produce less friction because more steel is in contact with the wood. The ease at which a borer penetrates wood depends on wood hardness, friction properties and capability/strength of the user.
