TECWERK Countersink 120° Ø16.5 mm HSS — 3‑flute, 10 mm shank

The TECWERK Countersink 120° Ø16.5 mm HSS is a precision form‑C countersink designed for burr‑free countersinking, deburring and chamfering in steel, cast iron and non‑ferrous materials

• HSS for durable cutting edges
• 120° angle for standard fastener countersinks
• 3‑flute geometry for smooth finishes
• 10 mm cylindrical shank for secure clamping

High productivity through engineered geometry

The countersink has been developed to deliver reproducible burr‑free results even under industrial workloads. Its 3‑flute cutting geometry reduces vibration and spreads cutting forces, which leads to a more consistent chamfer and a reduced risk of surface damage. The use of HSS ensures a resilient cutting edge that withstands intermittent loads, while the Form C profile provides a stable cutting line—together these features support shorter rework times and a steadier process flow, improving throughput on production lines and in busy workshops.

Clean finishes and reduced rework in demanding materials

Thanks to the 120° apex angle and sharp flute design, the tool produces clean countersinks suitable for standard fasteners and chamfers. The combination of right‑hand cutting and the flute geometry is ideal for deburring and gentle material removal, which helps avoid the rapid deterioration of finishes on non‑ferrous components. This results in fewer rejected parts and lower downstream correction costs. For typical workshop scenarios, the tool’s behaviour at low cutting speeds delivers superior surface quality and minimises the need for manual hand‑deburring.

Practical operating guidance for safe, efficient use

The countersink is supplied with a 10 mm cylindrical shank for reliable clamping in common toolholders. For steel workpieces under a cutting force of up to 500 N, the recommended feed is 0.14 mm/rev, which balances cutting efficiency with tool life. Operators should choose modest spindle speeds to exploit the tool’s best performance window; the specified configuration produces the best surface quality when used at lower cutting speeds, particularly on cast iron and light alloys. Correct clamping and steady feeds will extend service life and maintain a consistent hole geometry.

Why workshops and production engineers benefit

Adopting this countersink supports a predictable production process: the robust HSS material and stable cylindrical shank reduce tool change frequency, while the cutter geometry lowers the likelihood of chatter‑related defects. For maintenance shops, toolrooms and small‑batch manufacturers, the tool enables repeatable, high‑quality chamfering without complex setup. Combined with Metav’s supply chain and technical support, this tool contributes to reduced supplier counts and reliable replenishment for everyday operations.

FAQ

What materials can be processed with this countersink?
The TECWERK countersink is suitable for steel, cast iron and non‑ferrous and light metals, as indicated in the product description.

What spindle and feed settings are recommended for steel?
For steel under cutting loads up to 500 N, a feed of 0.14 mm/rev is recommended; modest spindle speeds deliver the best finish.

How does the 3‑flute design affect finishing?
The 3‑flute geometry reduces vibration and produces a smoother, burr‑reduced finish compared with higher‑helix or two‑flute variants.

Is the shank compatible with standard toolholders?
Yes—the 10 mm cylindrical shank is compatible with standard collet and chuck systems used in workshop and production environments.

Which SKU identifies this tool for reordering?
Reorder using SKU 2000865142NW to ensure the correct TECWERK countersink variant is supplied.
