Countersink 120° Ø16.5 mm HSS, 3‑flute (Shank Ø10 mm) — TECWERK

Countersink 120° Ø16.5 mm HSS, 3‑flute for burr‑free chamfering, deburring and countersinking in a wide range of metals

• HSS, Form C for robust edge life
• 120° cutting angle for precise countersinks
• Three flutes for smooth, burr‑free results
• Cylindrical shank Ø10 mm, right‑hand cutting

Faster, cleaner countersinking that reduces secondary work

The combination of HSS material with a 120° cutting geometry and 3 flutes produces consistently centred, smooth chamfers. This results in significantly fewer secondary finishing steps and reduced rework in batch production. The three‑flute design promotes uniform chip formation and evacuation, improving surface quality on the workpiece. In practical terms, the tool lowers cycle time per hole while maintaining the dimensional integrity required for accurate seating of fasteners and bearing faces.

Built for stable machining and repeatable results

A cylindrical shank Ø10 mm and a right‑hand cutting orientation provide secure clamping and dependable chip flow under standard clamping conditions. The tool is manufactured to Form C standards to balance toughness and sharpness, yielding long tool life under moderate cutting forces. The technical data specifies a recommended feed in steel of 0.14 mm/rev, which, together with a low cutting speed strategy, helps avoid work hardening and reduces thermal stress on the cutting edge. These parameters support reproducible finish quality in serial production.

Broad applicability across common workshop materials

This countersink is suitable for steel, cast iron and non‑ferrous metals, delivering the best results when used at lower surface speeds. Its geometry and material make it well suited to tasks such as deburring, chamfering and preparing holes for countersunk fasteners in both repair and production environments. The design supports use in conventional drilling machines and machining centres; clamping in a standard chuck or collet is straightforward, enabling flexible integration into existing workflows without special tooling investments.

FAQ

Which materials can be processed with this countersink? The countersink is suitable for steel, cast iron and non‑ferrous metals, providing clean chamfers and deburring for common workshop substrates.

What are the key dimensions and how are they held? The tool has a cutting diameter of Ø16.5 mm and a shank diameter of Ø10 mm; it is intended for standard chuck or collet clamping in drilling machines and machining centres.

What feed and speed recommendations apply? Use a relatively low cutting speed with a feed close to 0.14 mm/rev in steel for optimal edge life and minimal burr formation; adjust feed for softer materials accordingly.

Will the tool deliver burr‑free results on through‑holes? Yes—thanks to the three‑flute geometry and Form C design, the tool produces smooth chip formation and markedly reduced burrs on through and blind holes.

Which SKU should be ordered for this item? Order SKU 2000865142NW for the Countersink 120° Ø16.5 mm HSS, 3‑flute from TECWERK; this ensures the specified geometry and material properties.
