12D DIN 6537 Carbide Coolant-Thru Drills
These are German DIN 6537 standard-size coolant-through carbide drills. Für Ölgalerien, Zugstangen und tiefe Bohrungen in Schmiede- und Gussteilen. Erfordert steife Aufspannung und geringes Bohrunterlauf — IKZ ist bei dieser Tiefe unverzichtbar.

Applications
Oil galleries · Tie-rod holes · Forged steel parts · Cast housings with long oil passages
Feed-In Method
Start in a prepared pilot hole. Feed carefully through entry, run continuous internal coolant, and avoid peck cycles unless chips prove unstable.
Pilot Hole
Required for reliable entry and straightness. Use a short, high-accuracy pilot drill before the 12D tool.
Coolant Requirement
Internal coolant at 40-60 bar is required. Confirm pump flow and filtration before production.

Process Notes
What to Confirm Before Running 12D
Feed-In
Start in a prepared pilot hole. Feed carefully through entry, run continuous internal coolant, and avoid peck cycles unless chips prove unstable.
Pilot Hole
Required for reliable entry and straightness. Use a short, high-accuracy pilot drill before the 12D tool.
Cooling
Internal coolant at 40-60 bar is required. Confirm pump flow and filtration before production.
RFQ Data
Share drawing, required straightness, coolant pressure, fixture condition, material grade, and batch quantity.
