TPDB

The TPDB inserts ensure excellent hole quality thanks to high accuracy manufacturing process and strong clamping system.
It is specifically engineered for making deep holes with diameters bigger than Ø10 and deeper than 8 times of the drill diameter (8D). Therefore the TPDB is a reliable alternative to solid and brazed drills.

The TPDB additionally features KORLOY’s proprietary three dimensional chip breakers on the flutes. This system improves chip control and chip flow for an excellent surface finish. Its advanced holder surface treatment and insert coating technology maximize the tool life.
The TPDB also takes advantage of S-shaped cutting edges that have high rigidity and help achieve
vibration-proof drilling with small horse power machines
