Why the Four-Facet Split Point Boosts Drilling Accuracy
The four-facet split point on our jobber drills is like having a drill bit with sharpened senses—it helps the bit start squarely on the workpiece without wandering. Think of it like boot grips on ice; the edges bite in better so the bit doesn’t slip around when you first start. This means you get cleaner holes faster, with less frustration, especially on harder metals where precision is key.
