TECWERK 90° Countersink (DIN 335C), 20.5 mm, HSS TiAlN, 3‑flute

A TECWERK 90° Countersink (DIN 335C) designed for clean chamfering and deburring of holes in steel, cast iron and non‑ferrous metals

• DIN 335C 90° chamfer geometry
• TiAlN coating for increased tool life
• Three cutting edges for chatter‑free cut
• Cylindrical shank for secure clamping

Accurate chamfers with industry standard geometry

The TECWERK 90° Countersink (DIN 335C) combines standardised DIN 335 C geometry with a precise 20.5 mm cutting diameter to produce consistent chamfers and deburring results. The 90° angle is ideal for preparing holes for countersunk fasteners and for creating defined edges prior to assembly. The tool’s HSS substrate provides toughness for general steel and cast‑iron work, while a TiAlN coating reduces friction and increases heat resistance during sustained machining. For applications involving stainless or heat‑resistant steels an HSS‑Co variant is available, offering improved hot hardness and wear resistance.

Reduced vibration for cleaner finishes and faster cycles

Engineered with three cutting edges, the design produces a balanced, chatter‑free cut that reduces burr formation and minimises rework. The multiple cutting lips distribute cutting forces evenly, which helps to maintain surface quality at higher feed rates. For reference, a recommended feed in steel up to 500 N is 0.2 mm/rev, providing a guideline for efficient material removal without sacrificing finish. The cylindrical shank ensures secure clamping in standard tool holders, supporting repeatable positioning and rapid tool changes on production lines.

Durable coating and workshop benefits for daily use

The TiAlN coating significantly extends tool life by improving thermal stability and resistance to abrasive wear, which is especially valuable in high‑throughput environments. This durability translates into fewer tool changes, lower downtime and more predictable process costs. As a component of a wider workshop supply strategy, the tool supports efficient deburring and chamfering workflows, reducing manual finishing and improving overall part quality. The combination of standard compliance, robust substrate and coating makes the countersink a dependable choice for metalworking shops and industrial production.
