The Indexable Insert Drills are suitable for the length to diameter ratio below 3 in drilling process. Generally speaking, the diameter of holes are from 20mm to 30mm, also from 16mm to 350mm in shallow drilling.The short-hole drill is now available in sizes from 01 to 09, for producing holes 12.00 to 63.00 mm in diameter.The Indexable Insert Drills are high efficiency machine tools, in comparative advanced drilling tests, which has higher productivity than a solid-carbide drills.

The drills delivers a high penetration rate at a low machining cost per hole. Besides drilling high-quality holes with high reliability, it provides high machining security through its unique cutting action and advanced chip-evacuation design.

The Indexable Insert Drills have the advantage of high toughness of steel shank and excellence wear resistance of Carbide Inserts, which has the high efficiency and general purposes and long and reliable tool life.
