10.4mm Countersink DIN 335C 90° 3-Flute HSS Cylindrical Shank, Smooth Cutting - TECWERK

Precision chamfers and chatter-free finishes are delivered by the combination of HSS construction, the three-flute geometry and the 90° cutting angle; the cylindrical shank permits secure mounting for repeatable results — Order the TECWERK countersink directly via Metav Werkzeuge or ask our consultants if needed.

Countersink DIN 335 C 90° Ø10.4 mm HSS – 3-flute (TECWERK)

The TECWERK Countersink DIN 335 C 90° Ø10.4 mm HSS, 3‑flute is a precision tool for chamfering and deburring holes in steel, cast iron and non‑ferrous metals, designed for reliable, chatter‑free cutting in workshop and production environments.

• HSS high-speed steel construction
• 90° precision countersink angle
• Three-flute design for chatter-free cut
• Cylindrical shank for standard holders

Improve cycle times with predictable, high-quality chamfers

The three‑cut geometry and high‑speed steel body combine to produce consistent chamfering with minimal vibration. By using a three-flute design the tool delivers a smoother engagement with the workpiece, which reduces feed disruption and delivers reliable edge formation. With a recommended feed of 0.12 mm/rev in steel (at forces up to 500 N), the tool supports steady material removal rates that help keep process times predictable and lessen the need for rework. The DIN standard DIN 335 C designation signals an established geometry, making the tool suitable for repeatable production tasks where cycle stability is essential.

Durable construction for everyday workshop demands

A solid HSS body gives resilient cutting edges that stand up to frequent use, while the cylindrical shank ensures compatibility with standard holders for easy tool changes. This build favours workshops that require durability without complex maintenance regimes; routine inspection and light deburring keep the tool performing. The geometry is optimised for chamfering and deburring holes in steel, cast iron and non‑ferrous metals, yielding clean edges that simplify subsequent assembly or coating operations. Reduced chatter means fewer rejects and a neater part finish, which protects downstream processes and strengthens overall production quality.

Seamless integration and straightforward application guidance

Conformance to the DIN 335 C profile simplifies tool selection and replacement in mixed fleets. The countersink fits conventional toolholders and can be integrated into manual drilling stations or CNC cells where a fixed shank is required. The tool’s specification—90° angle and Ø10.4 mm nominal size—allows concise process planning for chamfer dimensions and seating forms. Clear feed guidance (0.12 mm/rev in steel up to 500 N) aids process engineers in setting reliable parameters, while the three‑edge geometry minimises burr formation and reduces secondary finishing. For procurement and supply continuity, the product is stocked through the Metav supply channel, which acts as a quality filter for European workshop demands.
