5D DIN 6537 Carbide Coolant-Thru Drills
These are German DIN 6537 standard-size coolant-through carbide drills. The 5D ratio extends reach without sacrificing the self-centering stability that defines solid carbide tooling. A versatile choice for components that require deeper holes than a 3D can reach — flanges, manifold bodies, hydraulic blocks — while still supporting aggressive feed rates with internal coolant.

Applications
Hydraulic manifolds · Flange holes · Pump housings · Medium-depth production drilling
Feed-In Method
Enter at reduced feed for the first 1-2D, then increase to production feed once the margins are fully guided.
Pilot Hole
Recommended for tight tolerance holes, angled entry, or unstable fixturing. A pilot about 1-2D deep improves straightness.
Coolant Requirement
Internal coolant at 20-40 bar is recommended to keep chips moving through the longer flute.

Process Notes
What to Confirm Before Running 5D
Feed-In
Enter at reduced feed for the first 1-2D, then increase to production feed once the margins are fully guided.
Pilot Hole
Recommended for tight tolerance holes, angled entry, or unstable fixturing. A pilot about 1-2D deep improves straightness.
Cooling
Internal coolant at 20-40 bar is recommended to keep chips moving through the longer flute.
RFQ Data
Send diameter, hole depth, coolant pressure, material, tolerance target, and required delivery date.
