Cutting Tool FANAR POGLEBIACZ DIN 335-C 10.4 HSSE countersink

FANAR POGLEBIACZ DIN 335-C 10.4 HSSE countersink is a solid high-speed steel cutting tool designed to perform precision deburring and countersinking on metal components. Produced to DIN 335-C geometry, this countersink provides a consistent chamfer and clean surface finish for holes created by drills or reamers. The 10.4 mm diameter is suitable for small to medium hole preparations where accurate seat and edge rounding are required in machining and finishing processes.

Advantages

The HSSE material ensures high wear resistance and thermal stability during repeated cutting operations, extending tool life under typical machining conditions. The standardized DIN 335-C geometry delivers predictable cutting behaviour and compatibility with fixtures and tooling systems that expect this profile. The 10.4 mm size offers a balance between rigidity and accessibility for use in confined or batch-production environments.

Suitable for

• Deburring and countersinking of holes in steel and non-ferrous metals
• Preparation of holes for fastener seating
• Machine tool and drill-press operations requiring DIN 335-C geometry
• Finishing operations in metalworking workshops and production lines

Key specifications

• Material: HSSE high-speed steel
• Geometry: DIN 335-C standard profile
• Working diameter: 10.4 mm
• Intended use: countersinking and deburring of drilled holes
• Compatibility: suitable for drill chuck or machine tool mounting

How to use

Mount the countersink in a compatible drill chuck, collet, or machine spindle ensuring concentric alignment. Select appropriate spindle speed and feed for the workpiece material to avoid overheating: lower speeds for stainless steels and higher speeds for softer non-ferrous metals. Advance the tool gently into the hole until the desired chamfer depth and edge break are achieved, then retract while the spindle is running to minimize burr formation. Inspect the chamfer and repeat if necessary, using coolant or cutting fluid when recommended for the material.

Usage recommendations

For optimal results, use appropriate cutting fluid with ferrous materials, maintain correct spindle speeds to reduce wear, and inspect the cutting edge regularly. Replace the tool when roundness or cutting performance degrades to preserve hole quality and prevent damage to workpieces.
