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.
Move Beyond Standard Tooling
Considering where a standard item’s functionality ends, there are endless possibilities. Yet even when budgets, and in some cases physics, get in the way, the only true limit is one’s imagination.

Digital tools are already here in the form of DROs and one-way communications to mobile devices, but that’s only the beginning. Get ready for some exciting breakthroughs in automation that promise higher productivity, increased safety, greater throughput and less scrap.
Bent Engineering successfully threaded 60 holes in shale gas blocks made of 17-4PH 900H stainless steel. How did they do it?
As the structural steel market looks for ways to make more parts in less time, some shops are finding a better way to manufacture steel beams with bolt holes.
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.
The balanced four-insert design of Walter’s D4120 helps deliver process reliability, enhanced surface finishes, and hole tolerances. Balancing cutting forces between the center and peripheral insert ensures hole-diameter precision.
Hoffmann Group’s Garant Master Steel Deep for deep hole drilling improves process reliability at higher cutting speeds. A design that reduces cutting forces and drill guidance that reduces vibration greatly improves hole quality in various machining applications.
Sandvik Coromant’s CoroDrill 860 with – GM geometry – drills a greater range of materials and applications and lasts much longer than its predecessor, the R840. Suitable for the automotive, general machinery, and oil-and-gas industries, where hole quality is critical.
