About Edge Finders
When drilling holes or cutting metal, using an edge finder helps you to locate the exact position you desire by measuring a pre-set distance from an edge. It allows you to position the centre of the mill spindle over the reference point. Some make a noise when placed in the proper position, while others require you to go slow and work until the dials are both at zero. For those who like a visual reference, there are edge finders that have an LED light that shows where to drill the hole. Another two features to consider include a magnetic tip to hold the finder in place and a titanium coating for rust resistance. If you are creating items often with a lathe or milling machine, you will want to look at an edge finder set. It is comprised of multiple styles so you can quickly change the tip. Purchase an edge finder on eBay to make precise holes or cuts that are less time consuming than measuring multiple times first.
