The Pen Reamer, model 316-2, manufactured by Bahco is a hand-operated reamer designed for use in fine and precision drilling. It has a length of 150 millimeters and is made of hard, shock-resistant high speed steel with a plastic coating on the exterior. The long, slim design of the reamer makes it capable of reaching narrow, hard-to-reach areas, where it can easily create or enlarge holes in a variety of materials such as wood, plastic, metal, and more. Additionally, the Pen Reamer's plastic coating provides an easier and more comfortable grip on the reamer, allowing for more efficient and accurate drilling.
