Walter Tools DC170 Supreme

Product system overview

DC170 Supreme is Walter's coolant-through solid-carbide drill family for high-performance drilling, with specified length variants from short through deep-hole ratios. Exact designation, diameter, depth ratio, WJ30EJ grade, shank, coolant, and current catalog status must be retained.

Industries and applications

• Production drilling in the ISO P and K material areas identified in Walter literature.
• Interrupted cuts and inclined exits using an exact drill and validated setup.
• Deep-hole drilling through 8xD, 12xD, 16xD, 20xD, 25xD, and 30xD variants with appropriate procedure.

Technical and quote details

• Walter's catalog identifies DC170 Supreme as a 140-degree coolant-through solid-carbide drill family.
• Cited 16xD tools use DIN 6535 HA shanks and WJ30EJ cutting-tool material.
• The family spans many diameter-specific designations rather than one orderable DC170 item.
• Official literature emphasizes land design, coolant grooves, chip evacuation, and stability.
• Diameter, usable depth, overall length, shank, grade, reconditioning strategy, and availability remain item specific.

Selection notes

Store the complete Walter designation, diameter, depth ratio, grade, shank, coolant, holder, and reconditioning status.

Use current Walter item records and holemaking cutting-data documentation before ordering or programming.

Variables to validate

• Depth ratio and diameter are embedded in the designation and cannot be inferred from the family name.
• Productivity comparisons depend on Walter test conditions and are not guaranteed for another machine or setup.
• Deep-hole use requires validated pilot, coolant pressure, runout, chip evacuation, entry, exit, and retraction procedure.
