Countersink DIN 335 C 90° Ø12.4 mm HSS, 3‑flute — TECWERK

Countersink DIN 335 C 90° Ø12.4 mm HSS, 3‑flute — a precision countersink for clean deburring and chamfering of drilled holes in steel, cast parts and non‑ferrous metals

• HSS according to DIN 335 C
• Three flutes for chatter‑free cutting
• 90° countersink geometry
• Cylindrical shank for secure clamping
• Suitable for steel, cast and non‑ferrous metals

Precision and productivity in every chamfer

The TECWERK DIN 335 C countersink combines a high‑speed steel (HSS) body with a defined 90° cutting angle to deliver repeatable chamfers and deburring operations. The three‑flute geometry reduces vibration and produces a chatter‑free cut, which directly improves hole quality and reduces rework. For workshops seeking consistent finish and reduced cycle time, the tool’s geometry translates directly into faster set‑ups and fewer rejected parts, while the cylindrical shank ensures reliable clamping in standard tool holders.

Material capability and machining guidance

Designed for countersinking and deburring in steel, castings and non‑ferrous metals, the tool’s material and geometry allow for controlled material removal across a range of substrates. The data indicates a suggested feed in steel (up to 500 N) of 0.14 mm per revolution, which balances cutting force and surface finish. When machining softer alloys, modest adjustments to feed or spindle speed will preserve edge life; when processing harder workpieces, the HSS construction maintains edge stability under typical workshop conditions.

Practical benefits for workshop workflows

The tool’s standard designation (DIN 335 C) and conventional cylindrical shank mean straightforward integration into existing tool inventories without special holders. The combination of HSS and the three‑cutting‑edge design results in a smooth finish that minimises secondary operations, delivering clear economic benefits such as reduced handling time and improved throughput. This makes the countersink particularly suitable for production cells and repair shops where consistent, high‑quality chamfers are required with minimal adjustment.

Handling and performance notes

Tool life and surface quality benefit from appropriate machining parameters and secure toolholding. The three‑flute profile aids chip evacuation and reduces the likelihood of scoring on the component edge, while the 90° angle produces a standard chamfer compatible with common fastener seats. For best results, inspect the tool before use for runout and ensure the holder maintains concentricity; the tool’s design supports predictable, repeatable performance across small to medium batch sizes.

FAQ

What materials can this countersink machine for? The TECWERK countersink is suitable for steel, cast parts and non‑ferrous metals, as specified for the DIN 335 C design.

How does the three‑flute design affect cutting behaviour? The three‑flute geometry provides a chatter‑free cut and improved chip evacuation, which enhances surface finish and reduces the need for secondary deburring with the TECWERK tool.

Is the tool compatible with standard holders? Yes — the cylindrical shank conforms to conventional holders and enables straightforward integration into existing setups.
