TECWERK Kegelsenker DIN 334 C – 60° HSS countersink, D 20 mm, 3 flutes

TECWERK Kegelsenker DIN 334 C 60° D.20mm HSS Z.3 is a high‑speed steel countersink designed for clean deburring, precise countersinking and reliable seating in a wide range of metals

• HSS material, DIN 334 C standard
• 60° countersink angle for precise seating
• Three-flute design for burr-free countersinking
• Cylindrical shank, right-hand cutting

Precise seating and clean deburring for consistent assemblies

The 60° geometry, specified to DIN 334 C, delivers precise countersink profiles suitable for standard flat‑head fasteners. Manufactured from HSS (high‑speed steel) and equipped with a three-flute cutting geometry, the tool produces burr‑free edges and reduced chatter when used at appropriate speeds. The three cutting edges distribute cutting forces evenly, which improves surface finish and reduces the need for secondary deburring. The specified feed 0.2 mm/rev in steel (up to 500 N) provides a reliable benchmark for process planning and helps maintain repeatable part quality.

Broad material compatibility and recommended cutting strategy

Engineered for work in steel, cast iron, non‑ferrous and light metals, the countersink achieves best results at low cutting speeds, where HSS retains toughness and resists edge deterioration. Lower spindle speeds reduce thermal load and flank wear, especially when countersinking ductile alloys that can smear. For harder workpiece batches, a conservative speed and the suggested feed value help maintain tool life and part integrity. The tool’s right‑hand cutting orientation matches standard machine tool setups and supports predictable chip flow.

Robust design for efficient workshop use

The cylindrical shank fits standard chucks and collets, simplifying tool changes and enabling straightforward integration into production routines. Right‑hand cutting and the balanced three‑flute layout reduce vibration and promote smooth entry, which is particularly beneficial when countersinking close to finished surfaces. The combination of DIN conformity and HSS construction means the tool tolerates conventional regrinding where relevant, extending service life and lowering total cost of ownership.

Practical tips for secure, repeatable countersinking

For repeatable results, clamp the workpiece securely and pilot with a suitable drill if required to control run‑out. Use cutting fluid for steel and cast iron to reduce heat and improve chip evacuation; air blow or light lubrication works well for aluminium and other non‑ferrous metals. The tool is particularly effective for deburring and creating clean sink holes prior to final assembly, reducing rework time and improving overall product appearance. By selecting the right speed and the stated feed of 0.2 mm/rev in tougher steels, production throughput and component quality are both optimised.

FAQ

What materials can be processed with this countersink?
This TECWERK 60° HSS countersink is suitable for steel, cast iron, non‑ferrous and light metals, providing clean countersinks and deburring across these materials.

Is the tool suitable for production use on a CNC machine?
Yes, the DIN 334 C geometry and cylindrical shank make the tool compatible with standard CNC setups; adhere to lower cutting speeds for optimal life and finish.

What feed and cutting speed are recommended for steel?
A reference feed of 0.2 mm/rev in steel (up to 500 N) is specified; pair this with conservative spindle speeds to reduce heat and wear.

Can the countersink be re‑sharpened?
The HSS construction supports regrinding where appropriate; follow workshop regrinding practices to maintain geometry and balance.

Which shank type does the tool have and how does it fit into chucks?
The tool features a cylindrical shank, designed for secure seating in standard chucks and collets for straightforward tool changes.
