Instead of a single wheel, this gauge has a heavy-duty pin for chatter-free marking along, across and on end grin. It also contains a secondary pin attachment to use as a mortice gauge. It has another pin that replaces the 4.90mm thick machined flat gauge face so it can be used as a divider/compass. Just like the digital wheel marking gauge, this gauge is made to same high quality standards as all iGaging products with an accuracy of up to 0.0254mm over the 150mm range. Due to its 3-in-1 functionality we recommend this gauge over the wheel marking gauge but you will be happy with either depending on personal preference.
This gauge is perfect for getting your measurements done quickly for marking out with a massive, easy-to-read LCD display that reads in metric, decimalized and fractional imperial in 1/128th graduations. It is IP54-splash water, oil and dust resistant. Very well-made and a pleasure to use.
