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.

After several thousand extractions the summer of 2023 and prior. This Increment Borer produces clean cores, no need to sharpen it, or you might wreck it. Id rate this tool as excelent.Ive tested 12'' 16'' 18'' and 20'' in .200'' over several years. Been getting consistant results. I have an 18'' .169" diameter, but I havent tested that yet. Too busy.The one problem weve been having in the .200'' Haglofs, Is when backing the bit out of the bole. Certain softer trees Doug Fir, True Firs, and any rot! require backward presure to extract the bit from the bole. You have to turn it counter clockwise and use your body weight to get it out of the tree. Its a bit awkward, and relies heavily on the locking latch.I friend pointed out, maybe from an engineering standpoint, the back threads could be increased in depth. or something in the bit design improved. thats wy we are looking at Matson, and other old bit designs.I have no Idea. Im just reporting my experience, one I know others share.

I expected the borer to last more than one field trip but the cap came off the spoon and I wasn’t able to keep using the borer. Once back home I was able to fix it.

I have a geology minor and i use my increment borer to test trees for salinity to support my hypothesis

This is a specialty tool that requires knowledge for use but it is simple and works great. Great for coring treated wood to test treatment penetration.
