Long Shank Carbide Burr

Long-shank carbide burrs for deep cavities, narrow channels and reach work a standard 6 mm shank cannot: 100, 150, 200 and 300 mm reach classes on 3 mm and 6 mm shanks. Heads keep the same SA–SM geometry codes as the standard range, YG8 grade, controlled braze joints so the head stays true at extended length. Check runout after seating — reach amplifies any collet error. Sources & standards: ISO 9001 quality management · UNSPSC commodity codes · eClass product classification
