3D Internal-Coolant Solid Carbide Drill

General-purpose 3D internal-coolant twist drills, diameters 3–20 mm. Select by diameter, shank diameter, and length; check hole depth and coolant conditions.

Model format

HZ08-3D-IC denotes an 8 mm cutting diameter, 3D catalogue depth class and internal coolant; EC denotes external coolant.

Specification differences

SD denotes shank diameter; different shanks or lengths at the same cutting diameter are distinguished by their actual specifications.

Holemaking selection

Check diameter, coolant type, shank diameter and flute length. The depth class is not the overall or flute length.
