Drilling Tools

Drilling tools are end-cutting tools designed for producing holes in a workpiece. The shank of a drilling tool incorporates flutes, or grooves, that allow for the entrance of fluids, along with ejecting the cut ships from the workpiece. Drilling tools vary widely, to accommodate the properties of the workpiece along with the radius and depth of hole desired. Some subcategories of drilling tools include twist drills, straight flute drills, crankshaft drills, extension drills, step drills, oil hole drills, three- and four-fluted drills, and combination drill-and-countersink.

Why are Three-Flute Drills Better?

The idea of adding a third cutting edge to drills for higher feed rates is nothing new, but the challenging chip evacuation made them suitable for only a few applications, such as machining cast iron. So how has this supposed slow seller made it into the top league of high performance tools for steel machining? A new design has harnessed the advantages of the three-flute drill for long-chipping steels and stainless steel materials.
