Deep Drilling Machines and Services

With the TBT deep hole drilling tools with indexable inserts you get a powerful system designed for high chip volume for use on machining centers and deep hole drilling machines.

Main features:
  1. High efficiency by specifically developed cutting edge geometry for optimal chip formation.
  2. Short downtime resulting from quick exchange of wear parts on the clamped tool.
  3. User-friendly as there is no regrinding and easy inventory of wear parts.
  4. Long tool life due to full coating and edge treatment
  5. Quick availability due to stocked wear parts.

The WP-ELB Series 10 is available in diameters ranging from 12,00 to 28,00 mm.
Drill heads are manufactured in 0,1 mm increments.
By means of adjusting shims, the bore diameter can be fine tuned

For cross drilling a version with extra long drill head and 3 additional guide pads is available as option.

The tool clamping on the machine is the same as with conventional deep hole drilling tools with brazed carbide head. There are all clamping elements available

You get the TBT single-lip drills with indexable inserts fully equipped and ready for use, together with the necessary key to change the wear parts.

The particular advantages of our double-lip drills are the high feed rates attainable in short-chipping materials, compared to the single-lip tools.

Various regrinding devices allow you to regrind your single-lip drill yourself. Our many years of experience in this area have been positively invested in the design and production of our grinding machines, jigs and associated accessories.
