Walter USA's DC160 X-treme Evo Advance Enables Precision Drilling
The DC160 X-treme Evo Advance solid carbide universal drill from Walter USA is designed for high positioning accuracy with a thinner web at the point and advanced positioning of the margins for hole guidance. A larger chip gash at the tool point is said to improve the tool’s point geometry, thus requiring less torque and feed force and improving tool life. The feature also moves the second margin forward, allowing it to engage sooner and improving the true position of the hole.
The DC160 is a four-margin drill which provides improved stability in uneven entrance and exits as well as cross holes or interruptions, according to Walter. It has an improved TiSiAlCrN/AlTiN multi-layer coating and can be used with or without internal coolant. The tool is available in lengths of 3 to 20 mm at 3×, 8× and 12×Dc; and in lengths of 3 to 25 mm at 5×Dc.
The drill can be used to machine all ISO material groups in a variety of applications such as inclined entries and exits, drilling holes close to the edge of the workpiece, or convex and concave surfaces, the company says.
Reducing cutting fluid use offers the chance for considerable cost savings. Tool life may even improve.
With macros and canned cycles resident in the CNC on most contemporary turning centers, single point turning of OD threads can seem like almost a default process decision. However, for numerous applications, OD thread rolling has inherent advantages as an alternative to cutting threads.
Running rotary milling cutters at the proper speeds and feeds is critical to obtaining long tool life and superior results, and a good place to start is with the manufacturer's recommendations. These formulas and tips provide useful guidelines.
