TECWERK 75° countersink Ø16.5 mm HSS, 3‑flute, shank Ø10 mm

TECWERK 75° countersink Ø16.5 mm HSS, 3‑flute, shank Ø10 mm is a tool for clean countersinking, deburring and recessing in steel and non‑ferrous metals

• HSS, Form C, 3 cutting edges
• 75° countersink angle for standard fasteners
• 16.5 mm nominal diameter for larger chamfers
• 10 mm cylindrical shank for secure clamping

Consistent, burr‑free holes for reliable assemblies

With its HSS construction and 3‑flute geometry, this countersink delivers a controlled cutting action that reduces tearing and vibration. The 75° angle aligns with common fastener seating profiles, producing reliable contact surfaces and predictable torque behaviour. For production environments where repeatability matters, the tool’s form and flute count ensure burr‑free results even at moderate feed rates, which helps to reduce rework and improve component fit.

Engineered for a range of metals with clear machining guidance

Designed for use on steel, cast iron and a variety of non‑ferrous materials, the tool’s right‑hand cutting geometry and Form C profile permit efficient material removal while limiting chatter. The specified feed in steel (up to 500 N) of 0.14 mm/rev gives a practical reference point for setting machine parameters; following this guidance supports consistent surface finish and extended tool life. For workshop operators unfamiliar with countersink feeds, this value provides a reliable starting point that balances cutting performance and tool wear.

Efficient cutting at lower speeds for improved tool life

The countersink is optimised for lower cutting speeds, which reduces heat generation at the cutting edges and preserves hardness in the HSS substrate. Reduced thermal stress translates into longer service life and steadier dimensional performance over series runs. In contexts where tool changeover time and downtime are costly, this translates into tangible productivity gains and fewer interruptions to workflow.

Simple handling and integration into existing setups

The 10 mm cylindrical shank fits standard collets and drill chucks, enabling quick tool changes and firm retention during operation. The combination of a compact shank and a 16.5 mm cutting diameter makes the tool versatile for both manual and CNC workflows. As a practical benefit, the countersink’s geometry minimises radial runout sensitivity, making it suitable for routine countersinking tasks across maintenance, prototyping and light production lines.
