Section shape steel used for constructions including hotels, hospitals, factories, offices and bridges is in demand continuously.


KORLOY launches exclusive top solid indexable drill, TPDB-H for drilling of steel-frame structure such as H-Beam, Angle, and Plate etc. according to the importance of section shape steel in the market.


TPDB-H insert with independent shape of double R point cutting edge ensures high quality surface finish even in vibrated machining due to its good centering and less cutting load.


In addition, the exclusive multi-layer PVD coating for drilling of steel-frame structure with high hardness and lubrication and surface treatment technology provide long tool life due to better chip evacuation and less wear on rake face and relief face.


The high helix angled flute of TPDB-H holders increases machining stability and productivity preventing vibration and unexpected fracture from chip blockage in drilling of thick workpieces.


TPDB-H will provide a rising solution for drilling of steel-frame structure.
