5mm x 70mm Carbide Tipped Boring Bit — 60° Point, Right-Hand

Description

The BBT057R is a carbide tipped boring bit — 5mm diameter, 70mm length, 60-degree tip — in right-hand rotation. The extended 70mm length over the 57mm standard (BBT055R) accommodates deeper boring operations or machines with longer clearance requirements between the boring head spindle and the panel surface. Right-hand rotation pairs with left-hand bits across the boring head to balance lateral forces. For 57mm right-hand, see BBT055R. For 70mm left-hand, see BBT057L. For brad point 70mm right-hand, see BBP057R.
