The Whole Picture in Holemaking

The exchangeable-tip drill is a good choice for a large range of holes limited by tolerances down to IT9 and often deeper than five times the diameter. CoroDrill 870 represents the new generation of this type of drill and is a reliable choice for many operations and a number of different workpiece types. 
Today’s holemaking techniques need to be more efficient than ever to meet greater demands and closer tolerances. Ultimately, the tool — and its application — matter. For optimal success, it's time to see the whole picture.

How New Spindle Connection Maximizes Metal Removal

From Weakest Link to Machining Superstar: The new KM4X™ design from Kennametal can perform from low-speed/high torque to high-speed/low torque when milling, drilling, and turning a wide range of materials to get the absolute most out of your production equipment.

Gun Drilling in Tool Steel

Toolox 44 has a high hardness of 45 HRC and an excellent machinability thanks to its low carbon content and high homogenity. Mold and die makers sometimes have machining difficulties the first time they use this steel in long hole drilling of cooling channels that are required in the tool. 
Swedish steel maker SSAB explains how progress is being made on long hole drilling in wear resistant and harder mold and die steels as a way to avoid heat treating.

Enhanced Indexable Drilling

Rising costs have caused a dramatic shift in the marketplace from solid carbide tooling to indexable and removable tip tooling. (Photo courtesy of OSG)
As markets reduce the number of machining operations, more complicated indexable drilling geometries are becoming more common. Finite element analysis software allows shops to better understand their processes, providing not only forces and chip shape results, but also stresses and temperatures throughout the cutting process.

Drilling, Tapping and Threading Holes

Take a look at some of the newest equipment and tooling that are helping shops make their holemaking operations more productive and profitable.

Exchangeable-Tip Drill Now Available for Stainless Steel

This design optimizes grade and geometry for steel to ensure hole quality for the intermediate hole-tolerance area of IT9-IT10. The drill is available in diameter range10.00 mm through 26.65 mm (0.394 in through 1.049 in) and lengths up to 8X drill diameter as standard. Each drill body has a unique interface size with matching tips to achieve hole tolerances of H9 through H10.
The CoroDrill 870 from Sandvik Cormant makes holes more efficiently and closer to required specifications required so they are better equipped for subsequent operations.
