TECWERK Countersink DIN 334 C — 25 mm, 60° HSS, 3 flutes

The TECWERK Countersink DIN 334 C is a high-speed steel countersink engineered for precise deburring, countersinking and chamfering of steel, cast iron and non-ferrous materials in production and workshop environments

• HSS construction for robust cutting
• DIN 334 C standard geometry
• 3-flute design for smooth finish
• Cylindrical shank, right-hand cutting

Reduced rework through stable geometry and material selection

The combination of DIN 334 C geometry and HSS (high-speed steel) delivers consistent cone shape and edge stability, which reduces the need for follow-up machining. The three-flute configuration produces a smoother surface than two-flute variants, lowering the risk of chatter and achieving a cleaner bore entry — a practical advantage when working on assemblies that require a flush fastener seat. This stability is particularly valuable in batch production, where repeatability and minimised rework translate directly into time savings and predictable throughput.

Controlled cutting for fragile and mixed materials

Designed for right-hand cutting with a cylindrical shank, the tool is optimised for deburring and finishing operations on steel, cast components and light metals. Best results are reported at lower cutting speeds, which helps avoid heat-related edge dulling and maintains surface integrity on softer alloys. The specified feed guidance—0.2 mm/rev under 500 N in steel—provides a clear baseline for setting machining parameters, enabling process engineers to balance material removal and finish quality without extensive trial runs.

Operational efficiency and tool life in routine workflows

A three-flute countersink offers a favourable trade-off between cutting aggression and finish: faster material evacuation than multi-flute finishing tools, while still delivering a fine edge. The cylindrical shank suits common drill-chuck or holder arrangements and supports quick changeovers on general-purpose spindles. For maintenance, regular inspection of cutting edges and adherence to the recommended low cutting speeds will extend service life and preserve the burr-free performance that prevents additional manual deburring. Economical procurement and predictable performance support continuous production with minimal interruption.

FAQ

What material is the countersink made from?
The countersink is manufactured from high-speed steel (HSS), providing wear resistance and edge retention for general workshop countersinking.

Which angle and diameter does the tool have?
The tool is a 60° countersink with a 25 mm diameter, following DIN 334 C geometry for standardised seating.

Is the tool suitable for aluminium and other light metals?
Yes; the design and material make the countersink suitable for aluminium and similar light metals, delivering clean deburring and chamfering.

What feed rate is recommended for steel applications?
A feed of 0.2 mm per revolution is indicated for steel under the specified cutting load, which helps achieve a smooth finish.

Can the countersink be used for finishing cast components?
The cutter is suitable for cast parts and provides burr-free results when operated at the advised lower cutting speeds.
