Solid Drilling Tools

Solid drilling tools, (without pre-bore) with indexable inserts, usually called U-Drills are mounted with centre cutting and peripheral cutting inserts with helical flutes. In most of the cases, they are two insert designs: single tip, with diagonally opposite cutting edges called as Spade Drills and for bigger diameters they can be configured with more than two inserts. These drills are also designed combining boring, facing & chamfering operation in one tool.
