TECWERK Countersink Set DIN 335 C, 90° — HSS‑Co, 6-piece

The TECWERK Countersink Set provides a compact solution for precision countersinking and deburring tasks in general workshop and industrial environments, designed to meet DIN 335 C requirements.

• DIN 335 C conformity
• 90° countersink angle
• HSS‑Co for improved wear resistance
• 6.3–20.5 mm diameter coverage

Precision that meets standards and reduces rework

The set is built to DIN 335 C tolerances and a 90° countersink geometry, ensuring a predictable chamfer suitable for many fastener head types. The combination of standard compliance and a three‑cutting‑edge design delivers a smooth finish on drilled holes and reduces the need for subsequent manual deburring. This translates into fewer rejects and lower rework times, supporting leaner production processes and consistent assembly quality.

Material choice for longer tool life and thermal stability

Manufactured from HSS‑Co (cobalt high‑speed steel), the cutters offer enhanced thermal stability and improved wear resistance compared with conventional high‑speed steels. The cobalt content helps maintain cutting edge integrity under higher temperatures, which means prolonged life under frequent or demanding use. For workshops seeking a balance between performance and replacement intervals, this alloy provides an economical step up in durability without moving into more specialised tool grades.

Versatile range and organised workshop handling

Covering a diameter span of 6.3–20.5 mm within a single 6‑piece set reduces changeovers and simplifies tool selection for everyday countersinking and deburring tasks. The cutters are supplied in a sturdy plastic case for organised storage and secure transport between job sites or within the toolroom. This practical kit suits maintenance departments and general workshops that require a ready set of sizes to deal with varied hole diameters while keeping bench space and tool management efficient.
