Suunto increment borers are used for examining wood quality and measuring growth rates. Suunto Increment Borers Story Suunto increment borers are used for examining wood quality and measuring growth rates. The extent of woodworm or termite damage, impregnation depth etc. can also be measured with these borers, which are made of finest steel. However, these special uses can cause extra wear to the borer bit. Suunto increment borers come core diameter are 5mm and are coated with PTFE to reduce friction heat (an important consideration when growing trees are involved). The PTFE coating also makes the borers easy to extraxt. Both thread styles (two and three threads) are designed to make the borer easy to extract from the wood. **Tips For Increment Borer Care With gloves on, use a "golf tee" to knock out any piece of core stuck in the tip. Never use a nail. When putting your bit back into the handle, never drop it in. Hold handle horizontal and gently slide the bit. Also, put a small piece of cardboard or cork at the bottom of the handle for extra bit protection and to take up any slack to prevent the bit from banging around inside the handle while in transit. At the end of the day, spray lubricant such as WD-40 inside and out of the bit to prevent corroding. Periodically use a rifle cleaning kit for a thorough cleaning.
