TECWERK countersink DIN 335C 90° Ø20.5mm HSS, 3‑flute

The TECWERK countersink DIN 335C 90° Ø20.5mm is a high‑speed steel chamfering tool designed for precise countersinking and reliable deburring of drilled holes in metalworking and light industrial settings

• HSS, DIN 335C standard
• 90° chamfer angle for countersinking
• Three‑flute design for chatter‑free cutting
• Cylindrical shank for standard tool holders

Consistent chamfers that reduce assembly time

Manufactured from HSS and conforming to DIN 335C, this countersink produces a repeatable 90° chamfer that simplifies subsequent assembly and surface finishing. The defined geometry ensures that fasteners sit flush and that mechanical fits meet tolerance requirements, which reduces the need for manual rework. For workshops and production lines the direct benefit is fewer rejects and a smoother downstream process when working with steel, castings and non‑ferrous metals.

Stable cutting and predictable feed for improved cycle times

The three‑flute configuration gives a balanced cut with a chatter‑free action, which improves surface quality and reduces vibrations compared with unequal‑flute tools. Where data allow, follow the recommended feed of 0.16 mm/rev at cutting forces up to 500 N to achieve the intended material removal and finish. This predictable performance helps planners optimise cycle times and operators to keep processes steady, translating into measurable productivity gains.

Simple integration into existing machining setups

A cylindrical shank provides straightforward mounting in standard chucks and holders, while adherence to DIN 335C means interchangeability across compatible tool inventories. The compact design reduces setup complexity and aids fast tool changes on busy benches. For small to medium enterprises and maintenance shops this means less downtime, easier stock management and a tool that fits into established workflows without additional adaptors.
