DIN 6537 Standard Sizes · Coolant-Thru Drill Depth Ratio
3D DIN 6537 Carbide Coolant-Thru Drills
These are German DIN 6537 standard-size coolant-through carbide drills. 3D — универсальный вариант для сквозных и коротких глухих отверстий. Самая жесткая серия в линейке: высокая прямолинейность в стали, чугуне и алюминии, стабильная подача и эффективный отвод стружки через внутренние каналы.
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.
