Seco Tools Crownloc

Product system overview

Seco Crownloc is an exchangeable-tip drilling family that combines reusable drill bodies with replaceable crowns. The exact Crownloc generation, body, crown diameter, geometry, grade, drilling depth, shank, and coolant configuration determine the usable assembly.

Industries and applications

• Production drilling where replaceable crowns reduce regrinding and drill-body replacement.
• Applications requiring repeatable crown positioning, internal coolant, chip evacuation, and material-specific geometry.
• Repeat holes where crown changes preserve a verified body, generation, diameter range, and drilling depth.

Technical and quote details

• Seco describes Crownloc with an interlocking interface, guided margins, self-centering geometry, and coolant delivery through the crown.
• Crownloc Plus is a newer and distinct branch with revised geometry, coating, and locking-interface features.
• Diameter and tolerance coverage varies by Crownloc branch and exact item.
• Body records must retain generation, diameter range, L/D, shank, locking interface, and coolant form.
• Crown records must retain diameter, geometry, grade, interface generation, and material application.

Selection notes

Keep body and crown identifiers linked with the generation, diameter, L/D, work material, coolant requirement, and current Seco compatibility evidence.

Record Crownloc Plus migration as a reviewed successor relationship rather than an assumed direct replacement.

Variables to validate

• Crownloc and Crownloc Plus should not be assumed cross-compatible.
• Diameter alone does not establish body, crown, geometry, grade, or drilling-depth compatibility.
• Tolerance, coolant, torque, and cutting data must be taken from the exact body-and-crown combination.
