TECWERK 90° Conical Countersink (DIN 335 C), 25 mm HSS — extra‑long, 3‑flute

TECWERK 90° Conical Countersink (25 mm) for reliable deburring, chamfering and countersinking of holes in steel, cast iron and non‑ferrous metals

• HSS construction, DIN 335 C compliant
• 90° three‑flute geometry for smooth finish
• Extra‑long cylindrical shank for deep reach
• Chatter‑free cutting action for consistent edges
• Suitable for steel, cast iron and non‑ferrous metals

High‑performance countersinking for steady production flow

The conical cutter is manufactured from HSS and conforms to DIN 335 C, delivering a robust combination of hardness and toughness that suits industrial use. The three‑flute design reduces vibration and enables a chatter‑free cut, which directly lowers the risk of rework and scrap in serial production. Feed guidance is concise and practical: with a recommended feed of 0.2 mm/rev in steel up to 500 N the tool achieves a clean chamfer and fast cycle times, improving throughput without sacrificing finish.

Versatile material compatibility and application benefits

Engineered for multi‑material use, the tool handles steel, cast iron and non‑ferrous metals with consistent results. The 90° cutting angle produces standard chamfers suitable for countersunk fasteners and deburring operations, while the extra‑long cylindrical shank provides access to deeper bore features and recessed areas. In workshops and production environments where varied materials are processed, this conical countersink reduces tool changes and simplifies setup, supporting smoother process planning and less downtime.

Precision, handling and tool life in daily use

The combination of HSS material quality and the three‑flute geometry not only improves surface quality but also distributes cutting forces more evenly, which helps to prolong service life under typical workshop loads. The cylindrical shank fits standard chucks and holders, ensuring secure clamping and repeatable concentricity. For users seeking measurable quality improvements, this countersink contributes to accurate chamfer dimensions and reliable edge preparation, supporting both manual finishing and CNC pre‑process operations.
