3D DIN 6537 Carbide Coolant-Thru Drills

These are German DIN 6537 standard-size coolant-through carbide drills. The 3D depth ratio is the workhorse of through-hole and short-blind-hole drilling. With the shortest flute-to-diameter ratio in the range, the 3D offers maximum rigidity and excellent straightness in steels, cast iron, and aluminium alloys. Ideal for high-feed automotive and general engineering applications where cycle time is critical.

Applications

Short through holes · Stable blind holes · Automotive brackets · General steel and cast-iron parts

Feed-In Method

Run directly after spot or chamfer preparation when the work surface is flat and rigid. Pecking is normally unnecessary with stable coolant flow.

Pilot Hole

Usually not required. Use a short pilot or spotting operation only on angled, cast, or interrupted entry surfaces.

Coolant Requirement

Use internal coolant or high-quality flood coolant at 15-30 bar. Keep filtration fine enough to protect small coolant channels.
