Kegelsenker EUC DIN 335 C, 90° – HSS three‑flute precision countersink by MAPAL

Kegelsenker EUC DIN 335C 90Grad D.10,4mm HSS spezial 3-Fl.schaft Z.3 BECK is a precision 90° countersink designed for fast, low‑force chamfering in a range of metals

• HSS special coating
• DIN 335 C compliance
• 90° precision countersink
• Reduces axial force by 50%

Faster chamfering with significantly reduced cutting forces

The specially engineered geometry delivers a measurable improvement in machining efficiency. Thanks to the EUC (extreme unequal pitch) and the three‑flute layout, the tool lowers axial force by approximately 50% and radial force by about 25%, which reduces required feed effort and diminishes chatter. This results in more consistent chamfers and less operator fatigue during prolonged runs. The combination of HSS base material and a special coating extends tool life under demanding conditions while maintaining sharp cutting edges.

Consistent, burr‑free chamfers through optimised cutting geometry

Precision in the cutting edge preparation and the optimised geometry enable reliable results on successive parts. The 90° angle conforms to standard chamfering requirements, while the radial relief grinding reduces rubbing and heat build‑up at the cutting zone. The resulting surface finish is cleaner and often requires less post‑processing, making the tool suitable for batch production where repeatability and reduced secondary operations are priorities.

Broad material suitability and practical machining data

The countersink is suitable for machining steel, cast iron and non‑ferrous metals, delivering predictable behaviour across these material classes. For steel the recommended feed is 0.1 mm/rev when cutting forces approach the indicated guideline, ensuring stable cutting without overloading the spindle. The right‑hand cutting action and DIN standard compliance facilitate integration into existing setups and tool libraries, while the precision execution supports tight tolerances in finish operations.

Durable design that supports productivity and process reliability

Constructed from HSS with a targeted special coating, the tool balances wear resistance and cutting performance. The radial relief and carefully prepared cutting edges reduce the likelihood of built‑up edge and limit vibration, which together contribute to longer times between tool changes and steadier component quality. The combination of these technical choices supports continuous production and helps to lower scrap rates in routine chamfering tasks.

FAQ

What materials can this countersink process effectively?
The countersink is suitable for steel, cast iron and non‑ferrous metals, delivering stable chamfering across these materials thanks to its HSS construction and special coating.

How does the EUC geometry benefit machining?
The EUC (extreme unequal pitch) reduces vibration and chatter, which lowers axial and radial forces and results in smoother cutting and improved surface quality.

What feed rate is recommended for steel?
For steel, a guideline feed of 0.1 mm/rev is recommended under cutting forces up to the specified guideline to maintain stable performance.

Is the tool compliant with industry standards?
Yes, the design follows DIN 335 C and the standard 90° countersink geometry for compatibility with common chamfering requirements.
