Through-hardened jawsDurable gripping surfacesFor corded or cordless reversible or non-reversible power drills

Self-tightening mechanism automatically increases the grip in proportion to the increase in torque during the drilling and avoids the tool slipping a clockwise rotationPrecision tested and certified to 0.0016" T.I.R max at half capacity

Precision tested and certified to 0.0016 in T.I.R. maximum at half capacityFor use on CNC machining centers in drilling, boring, counter-boring and milling operations requiring heavy penetrationFurnished with spanner wrench to allow the application of...
