Walter USA, LLC’s Walter Titex XD70 is a carbide drill that employs design and manufacturing innovations that bring new levels of productivity to the drilling of extremely deep holes, the company says.
The XD70 (the XD designation stands for “extremely deep”) can produce holes up to 70xD in one operation and does not require pecking. Previous XD technology product offerings topped out at 30xD, the company says.
Along with its design, manufacturing innovations have contributed to the drill’s increase in performance. The company is using a new method of producing solid carbide blanks, making it possible to efficiently manufacture this type of long solid carbide drill. In addition, a special grinding process is also employed.
As is the case with all XD drills, cooling for the XD70 is provided via internal coolant channels. However, despite the great drilling depth, no special coolant equipment, such as an external high-pressure system, is required. A standard cooling unit, such as those available with any machining center, is sufficient.
The XD70 technology is currently being offered as a special tool, in diameters ranging from 5 to 12 mm. Two-tip coatings are available, depending on the workpiece material: TTP for steels and XPL for cast iron.
