How to Thread Nickel-Based Alloys

This pipe tap uses Variable Helix Correction (VHC) technology that provides a specially ground relief geometry in the primary cutting zone, generating a smaller and tightly rolled chip formation.
Proper tooling selection is the key for optimal results in this demanding application.

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.

Cutting Wheel for Heavy Duty Steel and Stainless Steel Jobs

The 1/16 in thick ZIP+ XTRA cutting wheel from Walter Surface Technologies easily cuts through steel or stainless steel in heavy duty applications with an exclusive, patented rib design that reduces friction on the surface for faster and cooler cutting.
The ZIP+ XTRA cutting wheel from Walter Surface Technologies uses an exclusive, patented rib design that reduces friction on the surface for faster and cooler cutting in the most demanding applications.

New Cutting Edge Geometry for Stainless Steels

The chamfer and thread relief geometry of the XTOP tap reduces the torques generated during chamfering operations and at the reversal point. In deep blind hole threads up to 3xD, chips can be optimally guided and sheared off without any problems in reverse motion, even with problem materials. (Photo courtesy of WEXO) (first view)
These special tools have been developed for increasing process reliability when machining problematic materials with higher ductility.

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.
