A 90 Deg Indexable Spot Drill is a specific type of cutting tool used in machining operations to create precise spot holes or divots on a workpiece surface. It has a cutting edge that forms a 90-degree angle, creating a flat-bottomed conical depression when cutting into the workpiece surface. Its indexable design and cutting geometry ensure accurate hole placement and efficient machining operations in various manufacturing and machining applications. They typically leaves a clean and flat-bottomed spot, which is advantageous for precise hole location and subsequent machining operations. 90 Deg Indexable Spot Drill is a specialized cutting tool designed for creating precise spot holes or divots on workpiece surfaces.
