Total TAC101603 HSS drill bit 16mm 5pcs

5-Piece Large-Diameter Set: Provides multiple 16.0 mm bits for heavy fabrication, M16 bolt clearance holes, and high-torque structural metalwork.

Reduced Shank Design: Machined shank down to 13 mm ensures compatibility with standard 1/2-inch (13 mm) drill chucks without requiring a specialized larger drill press chuck.

135° Split Point Tip: Self-centering point prevents bit wander on smooth or rounded metal surfaces, ensuring precise, clean starts without a center punch.

High-Volume Spiral Flutes: Deep polished helical flutes rapidly lift thick metal swarf out of deep holes to maintain cutting efficiency and control thermal stress.
