In response to increased industry demands for precision, Walter USA LLC has expanded its high-performance line of Titex X-treme DM micro drills with the addition of products in the 16xD and 30xD drilling depth ranges. In addition, diameters of 2 to 2.95mm are now available for all drilling depths in these product ranges. Formerly the 2mm diameter was available only in sizes smaller than 25xD.
Whether automotive, aerospace, die and mold, or general metalworking, industries increasingly require a multitude of drilled holes with diameters smaller than 3mm. Sometimes drilling depths of up to and over 30xD are required. Typical applications include drilled holes for lubrication, cooling, venting, and nozzle bores.
Walter has reportedly succeeded in bringing the superior performance of its Titex X-treme DM family into the micro drill range due to a series of features that are typically not found in small diameter drills. First, these new Walter micro drills have internal cooling, just like the larger members of the X-treme family. Furthermore, their optimized point geometry with special cutting edge preparation and precisely dimensioned flute geometry ensure superior chip formation and, therefore, very high process reliability. The polished surface of the flutes also supports excellent chip evacuation.
The X-treme DM micro drills have a wide field of application, including the P, K, M and N ISO material groups. Importantly, the new DM micro drills allow the drilling process to take place without pecking. Pecking would cause additional load change and make the process unsafe.
Conditioning of the cutting edge, such as a honing or chamfering, to make it stronger and less susceptible to chipping. A chamfer is a bevel on the tool’s cutting edge; the angle is measured from the cutting face downward and generally varies from 25° to 45°. Honing is the process of rounding or blunting the cutting edge with abrasives, either manually or mechanically.
Any manufacturing process in which metal is processed or machined such that the workpiece is given a new shape. Broadly defined, the term includes processes such as design and layout, heat-treating, material handling and inspection.
The MC377 Advance, with protective chamfer, corner radii, and center cutting edge, can be used for chrome-nickel and steel materials, as well as titanium. The MD377 Supreme is a solid carbide milling cutter with a corner radius and central internal coolant engineered for titanium machining.
The MC128 Advance boasts a wide diameter range of 1/4 -3/4 in. (2-25 mm) with a TiAIN coating for universal use. WJ30TF grade is available for ISO materials P, M, K, and S. The MC128 Advance is well suited for die and mold work as well as general metalworking. The MD128 Supreme provides 64% more…
With this new tool, V or D-style inserts with just two cutting edges and lower stability (ISO VBMT, VCMT, DCMT) are replaced with triangular cutting inserts with three cutting edges and high stability. These three-edged inserts allow for a 50° undercut angle, ideal for profiling operations. Since…
The Walter MD838 Supreme (conical version) has an effective radius of 250-1000 mm, a corner radius of 0.5 - 4.0 mm and is available in diameters of 6-16 mm. Walter also offers a version of this tool with ConeFit exchangeable head. The MD839 Supreme (tangential version) has an effective radius of…
High tool life is achieved thru WEP10C coated cermet grade with multilayer TiCN TiAlN PVD coating and fine cermet micro grain. The combination of edge preparation and grade also ensures dimensional stability over long periods of time, which boosts productivity in mass production
The unique TiAlN-Al2O3 multilayer coating system makes the WSP45G both hard and tough, and thus extremely resistant to abrasive wear and high temperatures, with controlled residual stresses and less flank wear, all boosting tool life. A special mechanical post-treatment improves hairline crack…
Enhancements to the Xtra·tec XT M5130 milling cutter, including a new clearance angle of 7° have added to this universal tool's existing benefits of high performance, high surface quality, exceptional reliability and safety, and outstanding versatility. The M5130 handles a wide array of…
Accure·tec adaptors are ideally suited for the Walter Xtra·Tec® XT milling cutter range. This makes the system highly versatile. For example, for components with deep cavities in aircraft construction and aerospace industry in general, as well as the automotive, energy, die/mold, and general…
The Xtra·tec XT M5012 is highly cost-effective thanks to inserts being offered in a fully ground configuration for maximum precision, or fully sintered configuration for maximum cost efficiency. The bodies are offered in either ScrewFit or shell mount and with two pitches for different applications.
The M5137 Xtra·tec® XT boasts reduced process costs thanks to its Tiger·tec® coating and six cutting edges per indexable insert. This translates to simple tool selection and low cutting material costs, and highly cost-effective operation due to low unit costs.
