Description
The BBT087L is a carbide tipped boring bit — 8mm diameter, 70mm overall length, 60-degree tip — in left-hand rotation. The 70mm length accommodates deeper boring requirements or machines with more clearance between the spindle and workpiece than the 57mm standard (BBT085L). Used for 8mm dowel holes and hardware bores in CNC multi-spindle boring operations. For 57mm length left-hand, see BBT085L. For right-hand 70mm, see BBT087R. For brad point 8mm 70mm left, see BBP087L.
