Cross‑hole countersink 20–25 mm, 90° – HSS‑Co, TECWERK

The Cross‑hole countersink 20–25 mm, 90° HSS‑Co is a cylindrical‑shank countersink engineered for burr‑free countersinking and reliable deburring across steel, cast iron and non‑ferrous alloys

• Cobalt HSS construction for long tool life
• 90° countersink angle for standard chamfers
• 12 mm cylindrical shank for stable clamping
• Chip evacuation via hole prevents clogging

Consistent burr‑free chamfers even on demanding materials

The cobalt high‑speed steel construction delivers a shearing cut that produces clean edges with minimal burring. The 90° geometry yields standard chamfers suitable for fastening preparations and aesthetic finishing alike, while the tool’s material selection balances wear resistance with toughness. This combination reduces the need for secondary manual finishing and supports stable, repeatable edge quality across mixed production runs.

Predictable chip control for steady machining cycles

Thanks to the through‑hole design, chip evacuation is guided away from the work interface, which prevents chips from jamming between tool and component. In practice this lowers the risk of chatter and surface marks and contributes to uninterrupted process flow. The tool delivers recommended performance at a feed of 0.2 mm/rev under cutting forces up to 500 N, making it suited to controlled, low‑speed countersinking strategies that favour surface integrity.

Secure mounting and compact overall length for better handling

A 12 mm shank provides a compact and robust clamping interface, promoting concentric stability during rotation and reducing run‑out at the holder. The 102 mm overall length gives a practical balance between accessibility in deeper set‑ups and rigidity for precision work. The cylindrical shank geometry supports consistent concentricity, which is beneficial where precise alignment and repeatability are required.

Clear application profile and recommended machining approach

Designed for burr‑free countersinking and deburring of steel, cast iron, and light non‑ferrous metals such as brass and aluminium, the tool performs best at lower cutting speeds where the HSS‑Co grade exhibits optimal toughness. A shearing‑type flute geometry aids chip formation, so operators should prioritise steady feeds and monitor cutting conditions to extend tool life and secure consistent edge quality.

FAQ

What materials can be machined with this countersink?
The cross‑hole countersink is suited to steel, cast iron and non‑ferrous/light metals, providing burr‑free countersinking and effective deburring in these materials.

What makes the chip evacuation effective?
The tool’s through‑hole guides chips away from the cutting zone; this chip evacuation reduces clogging and helps maintain a stable surface finish during countersinking.

What shank size does the tool have?
The countersink features a 12 mm shank, which offers a stable clamping interface for improved concentricity and reduced run‑out.

Which feed and cutting force are recommended?
For steel, the data indicates a feed of 0.2 mm/rev at cutting forces up to 500 N to obtain the best surface results and tool life.

Is the cutting material suitable for demanding operations?
Yes, the HSS‑Co grade combines hardness and toughness, making the countersink appropriate for controlled, low‑speed machining where a shearing action is preferred.
