Walter DC170 Supreme
Walter DC170 Supreme is a coolant-through solid-carbide high-performance drill designed primarily for ISO P steel and ISO K cast-iron applications. Walter positions the family for high productivity, stable guidance, interrupted cuts, and inclined exits across general engineering, automotive, energy, and tool-and-mold work.
Product system overview
Walter DC170 Supreme is a coolant-through solid-carbide high-performance drill designed primarily for ISO P steel and ISO K cast-iron applications. Walter positions the family for high productivity, stable guidance, interrupted cuts, and inclined exits across general engineering, automotive, energy, and tool-and-mold work.
Industries and applications
- Use DC170 Supreme for production drilling in steels and cast irons where coolant-through delivery, hole quality, and tool-life consistency are priorities.
- Walter identifies interrupted cuts and inclined exits as supported application conditions, subject to the exact drill, setup, and cutting data.
- The family can run with emulsion or oil; coolant pressure, filtration, runout, holder condition, and pilot strategy remain application-dependent.
Published technical profile
- Tool architecture: solid-carbide drill with internal coolant channels and a geometry intended to maintain circumferential guidance.
- Primary material groups: ISO P steels and ISO K cast irons in Walter public product material.
- Application conditions: Walter identifies interrupted cuts and inclined exits among the family use cases.
- Available depths and dimensions vary by item; public product records include multiple diameter and drilling-depth combinations rather than one universal range.
- Walter reports higher productivity and longer tool life than conventional solid-carbide drills in its published product messaging; actual gains require a controlled application trial.
Selection notes
Shortlist DC170 Supreme for stable high-output steel or cast-iron drilling, particularly where interrupted conditions or inclined exits make guidance important.
Validate the exact Walter item against hole diameter, depth, tolerance, coolant, holder, machine power, and expected regrind or replacement strategy.
Variables to validate
- DC170 Supreme is a family of item-specific drills; diameter, usable depth, overall length, shank, point geometry, and grade must be taken from the selected product record.
- Manufacturer performance percentages are comparative claims under Walter test conditions and should not be treated as guaranteed shop-floor results.
- Machine condition, holder runout, coolant quality, entry and exit geometry, and work-material variation can materially change performance.
