Countersink Set DIN 335 C – 90° EUC, HSS, 6.3–25 mm (MAPAL)

Countersink Set DIN 335 C for precision deburring and countersinking in common workshop materials, designed to reduce feed forces and minimise chatter while maintaining consistent hole quality

• HSS with special coating
• 90° precision countersinks
• Reduces axial force by 50%
• Suitable for steel, cast iron and non‑ferrous metals

Higher throughput through lowered cutting forces

The Countersink Set DIN 335 C delivers measurable efficiency gains in series and repair work. Constructed from HSS with a special coating, the geometry and extremely unequal pitch (EUC) reduce axial force by 50% and radial force by 25%, which translates into noticeably lower feed effort and reduced tendency to chatter. Three precisely prepared cutting edges ensure smooth chip flow and predictable material removal. For production managers and workshop engineers, these characteristics mean fewer tool changes, less rework and a more reliable process window when preparing countersinks and deburring holes.

Reliable performance across common workshop materials

Engineered for use on steel, cast iron and non‑ferrous metals, the countersinks combine a cylindrical shank and right‑hand cutting action for straightforward integration with standard toolholders and drills. The cutting geometry is radially relieved, which improves surface finish and reduces side loads during operation; this is particularly beneficial when machining less rigid setups or thin‑walled assemblies. The set covers the practical diameter range of 6.3–25 mm, providing a compact selection for most maintenance and production tasks. Packaged in a sturdy plastic box, the tools are easy to store and identify between jobs.

Precision design that reduces rework and supports consistent results

Compliance with DIN 335 C and a precision execution ensure repeatable countersink angles and uniform chamfers, improving assembly fit and screw engagement. The combination of prepared cutting edges, the new geometry and 3 cutting edges gives a clean, burr‑minimised finish that reduces downstream deburring. The result is improved assembly reliability and a cleaner appearance without additional manual finishing. For quality officers and workshop supervisors, the set represents a pragmatic balance between durability, process stability and finishing quality.

FAQ

What materials can be processed with this countersink set?
The Countersink Set DIN 335 C is specified for steel, cast iron and non‑ferrous metals, as noted in the product data.

How does the EUC geometry benefit machining?
Extremely unequal pitch (EUC) in the design of the Countersink Set reduces harmonic vibrations, lowering radial loads and improving surface finish during countersinking.

What improvements in feed force can be expected?
Tests and tool geometry show the set reduces axial force by around 50% and radial force by approximately 25%, which eases feed demands and reduces chatter.

Is the set suitable for production or only for maintenance work?
The precision execution and HSS construction make the set suitable for both production environments and workshop maintenance where consistent countersink quality is required.

How is the set delivered and stored?
The tools are supplied in a plastic box, providing organised storage and protection between uses.
