Darex XT3000 Shank Attachment

Darex Drill Sharpener XT3000

An interchangeable chuck attachment for accurately sharpening Morse taper and common shank drills is the latest addition to the Darex XT3000 Xpandable Tool Sharpener system from leading workholding and machining equipment supplier, 1st Machine Tool Accessories Ltd (1st MTA).

Suitable for 3-12 mm (1/8 – 31/64 in) diameter No 0, 1 and 2 Morse taper or common shank drills, the new Darex accessory allows standard or split point tools to be quickly and effectively reground 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 Darex XT3000 is an affordable drill sharpening system that is designed to grow with customers’ individual requirements. It meets or exceeds international aerospace standards for controlling key geometry variation – 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 for sharpening drills up to 21 mm (13/16 in) as standard. The XT3000 is equipped with long-lasting, super abrasive CBN wheels for high speed steel and cobalt drills, or can be supplied with diamond wheels for carbide tooling. Both wheel types are zero-maintenance and will never require dressing throughout their life.

The new chuck attachment is the latest addition to an expanding range of XT3000 optional modules that includes a large capacity unit for drills up to 30 mm diameter (1.182 inch) and a countersink module for regrinding Weldon type or single flute countersink tools. A dedicated step drill unit for sharpening tools with a maximum pilot diameter of 12.7 mm (½ in) and step sizes up to 21 mm (53/64 inch) is also available, along with attachments for sheet metal point (Brad Point) and 90 degree point drills ranging from 3-21 mm (1/8 – 13/16 in) diameter. All accessories are fitted to the XT3000 base by hand and adjusted without the need for any tools. The sharpener is powered by a rugged ¼ hp motor, which is rated for continuous use, and the system’s enclosed design incorporates a vacuum extraction port for clean and safe operation.
