DIN 6537 Standard Sizes · Coolant-Thru Drill Depth Ratio
15D DIN 6537 Carbide Coolant-Thru Drills
These are German DIN 6537 standard-size coolant-through carbide drills. Im Bereich klassischer Tiefbohrverfahren — mit geringerem Aufwand als BTA. Für Kurbelwellen-Ölbohrungen, lange Schrauben und Wärmetauscher. Voller Innenkühlungsquerschnitt nötig.
Applications
Crankshaft oil passages · Long tie bolts · Heat-exchanger plates · Deep mould cooling features
Feed-In Method
Use a dedicated pilot hole, low runout holder, and controlled feed-in. Once guided, run steady feed with no dwell.
Pilot Hole
Required. Pilot hole quality controls entry accuracy and tool life at this depth ratio.
Coolant Requirement
Internal coolant at 50-70 bar with stable flow is recommended; verify filtration for small diameters.
