Kitagawa Europe Ltd is introducing the Darex XT3000 Xpandable Tool Sharpener, a modular regrinding system geared to the needs of machine shop users.
Designed as an affordable drill sharpener that will grow with customers' requirements, the XT3000 base unit quickly and accurately regrinds 3-21mm (1/8-13/16 inch) diameter standard or split point tools at any angle between 118 and 150 degrees. It also enables each drill's tip profile to be controlled precisely, including the required relief angle and split point configuration.
The unit meets or exceeds international aerospace standards for controlling key geometry variation - thereby ensuring precise drill performance. It also incorporates roller bearings for consistent accuracy over an extended service life and is supplied with two stainless steel chucks as standard. The XT3000 is equipped with long-lasting, super-abrasive CBN wheels for sharpening high-speed steel (HSS) and cobalt drills, or it can be supplied with diamond wheels for carbide tooling. Both wheel types are zero-maintenance and will never require dressing throughout their life.
The base unit¹s capabilities can be extended through the use of a series of easily fitted optional modules. These include a large-capacity unit for drills up to 30mm diameter (1.182 inch) and a countersink module for regrinding Weldon type or single-flute countersink tools.
A dedicated step drill unit sharpens tools with a maximum pilot diameter of 12.7mm (1/2 inch) and step sizes up to 21mm (0.826 inch). Further modules are available for sheet metal point (Brad Point) and 90-degree point drills ranging from 3-21mm (1/8-13/16 inch) diameter.
All adjustments and the attachment of modules to the XT3000 base unit are made by hand, without the need for any tools. The sharpener is powered by a rugged 1/4HP motor, which is rated for continuous use, and the system's enclosed design incorporates a vacuum extraction port for clean and safe operation.
