Solid drills up to 5xD

KOMET KUB Pentron®

The KOMET KUB Pentron®  was developed for continuous solid drilling up to 5xD, even in extreme drilling conditions which were previously limited to 3xD.

This solid drill combines key features such as excellent dimensional accuracy, high performance parameters and deep-hole drilling in one tool.

The KOMET KUB Pentron also achieves up to 20% greater feed and speed rates compared to similar drills.


  • Ideal for extreme machining situations
  • For deep-hole drilling
  • For steels, cast iron, aluminum and stainless materials
  • Diameter range from 0.562" to 1.750" (14.0 to 46.0 mm), 4xD and 5xD

Your PLUS:

  • Longer tool life and outstanding drilling performance due to optimum main body stability and special surface treatment
  • Excellent dimensional accuracy in extremely difficult drilling conditions up to 5xD
  • Simple and cost-effective inventory management thanks to identical internal and external indexable inserts
  • Maximum insert life through four usable cutting edges and the use of modern substrates and coatings
  • Optimum chip removal




Extreme applications in the 5xD range:

Drilling on an acute corner

Drilling on an edge

Drilling through stacked plates

Drilling on a welded seam or on uneven surfaces
