TECWERK Countersink 120° Ø6.3 mm — HSS, 3-flute, shank Ø5 mm

A TECWERK Countersink 120° Ø6.3 mm engineered for burr-free countersinking, deburring and spot chamfering across steel, cast and non‑ferrous light metals.

• 120° chamfer angle for standard countersinking
• High-speed steel, Form C, 3 flutes
• 5 mm cylindrical shank for standard holders
• Optimised for low cutting speed for best finish

Precision performance for consistent seating and deburring

The TECWERK Countersink 120° Ø6.3 mm HSS delivers reliable geometry and a consistent chamfer angle, ensuring fast, repeatable results in assembly work. Manufactured in HSS and executed in Form C with 3 flutes, the tool is designed to cut cleanly and resist wear during intermittent use. The 120° angle provides a standard chamfer suitable for most countersunk fasteners while the burr‑free cut reduces subsequent finishing operations. The result is improved process efficiency and fewer rejects in repetitive production or workshop tasks.

Compatibility and high‑quality surface finish in mixed materials

The tool combines a 6.3 mm cutting diameter with a 5 mm cylindrical shank for use in common collets and chucks. Right‑hand cutting geometry and three cutting edges produce uniform chips and minimise vibration, which is especially beneficial when working with steel, cast iron, non‑ferrous and light metals. Because the design favours lower cutting speeds, surface integrity is improved and chatter is reduced; this leads to fewer reworks and more reliable seating for fasteners and rivets in multi‑material assemblies.

Practical guidance on feeds and working conditions

For effective results the countersink is recommended to be used at reduced surface speeds; the tool achieves best finishes at a low cutting speed and a recommended feed in steel up to 0.09 mm/rev (at moderate cutting forces up to 500 N). The cylindrical shank facilitates quick tool changes and steady clamping, while the right‑hand cut allows conventional spindle rotation. These parameters make the tool suitable for manual bench work and machine setups where consistent, burr‑free chamfers are required without excessive cycle times.

FAQ

What materials can this countersink machine reliably handle?
The countersink is suitable for steel, cast iron, and a range of non‑ferrous and light metals, delivering burr‑reduced chamfers across mixed material jobs.

What are the key dimensions and how is it mounted?
The tool has a 6.3 mm cutting diameter and a 5 mm cylindrical shank; it mounts in standard 5 mm collets or chucks for fast changes and steady clamping.

Is the tool optimised for high spindle speeds?
No. The geometry is optimised for low cutting speed, which improves surface finish and reduces chatter when chamfering and deburring.

What feed should be used when countersinking steel?
A recommended feed in steel (up to 500 N cutting force) is 0.09 mm per revolution, balancing chip evacuation and surface quality.

Does the countersink suit machine and manual workshop use?
Yes. The combination of a 5 mm shank and three cutting edges makes the tool compatible with machine spindles and manual toolholders for routine workshop countersinking.
