The Darex XT-3000 Auto automatic drill sharpening machine has been introduced in the UK by 1st Machine Tool Accessories (1st MTA). It is said to bridge the gap between a manually operated machine and a fully automated CNC sharpening system.

XT-3000 Auto automatic drill sharpening machine

The automation attachment is factory fitted to a new unit but can also be retrofitted by 1st MTA to existing Darex XT-3000s in the field.

It allows the user to align standard conical drills, push the start button and step away. The auto sharpening system regrinds the bits without any further operator intervention, displaying relevant information on an LCD screen. Drills in the diameter range 3–21mm can be processed, although with an adapter bits up to 30mm can be sharpened.

Key features and benefits

  • The unit can be used by shop-floor staff to sharpen worn drill bits rapidly and consistently, saving the cost of buying replacements, so manufacturers will see a fast return on investment, according to 1st MTA.
  • The high level of repeatability is achieved whatever the skill level of the operator.
  • Many types of right- and left-hand twist drills can be sharpened for machining metals and non-metallic materials, and adapters are available for step drills, countersinks, brad points and 90° points.
  • The unit has the ability to count how many sharpenings it has completed and displays the number on the screen, allowing timely maintenance to avoid unscheduled downtime.
