8D DIN 6537 Carbide Coolant-Thru Drills
These are German DIN 6537 standard-size coolant-through carbide drills. 8D adressiert Tiefbohranwendungen mit Spanstau und Wärmeaufbau. Innenkühlung hält die Temperatur und spült Späne — gleichbleibende Qualität in Stahl, Edelstahl und Gusseisen.
For buyers checking Gühring 8D drill price, this page gives a factory-direct DIN 6537 size table, visible reference prices, pilot-hole guidance, coolant requirements, and RFQ data for evaluating a cost-effective alternative.

Applications
Deep holes in steel · Ductile iron components · Stainless manifolds · Oil and coolant galleries
Feed-In Method
Use a pilot hole, enter at low RPM/feed, then switch to full speed after the drill is supported. Avoid dwell in the hole.
Pilot Hole
Recommended. Pilot diameter should match the drill tolerance closely and guide at least 1.5-2D.
Coolant Requirement
Internal coolant at 30-50 bar with clean filtration is strongly recommended for chip evacuation.

Process Notes
What to Confirm Before Running 8D
Feed-In
Use a pilot hole, enter at low RPM/feed, then switch to full speed after the drill is supported. Avoid dwell in the hole.
Pilot Hole
Recommended. Pilot diameter should match the drill tolerance closely and guide at least 1.5-2D.
Cooling
Internal coolant at 30-50 bar with clean filtration is strongly recommended for chip evacuation.
RFQ Data
Include machine model, toolholder, coolant pressure, material hardness, hole depth, and whether the hole is blind or through.
