TECWERK Countersink DIN 335 C, 90° Ø 6.3 mm, HSS, 3‑flute

The TECWERK Countersink DIN 335 C is a 90° high‑speed steel tool with a cylinder shank, designed for precise countersinking and deburring of drilled holes in metalworking applications.

• HSS construction for high‑temperature resilience
• 90° precision countersink angle
• Three‑flute design for chatter‑free cutting
• Cylinder shank for secure toolholding
• Suitable for steel, cast and non‑ferrous metals

Precision finish that reduces rework and scrap

The DIN 335 C countersink delivers a consistent chamfer thanks to its HSS body and geometrically balanced three‑flute cutting edges. The result is a chatter‑free operation that produces repeatable chamfers and clean edges, reducing the need for secondary finishing. In manual and machine applications alike, a controlled cut geometry minimises radial vibration and ensures holes are ready for countersunk fasteners or cosmetic finishing with fewer rejects. This precision supports higher first‑pass yields and a steadier production flow.

Faster throughput with predictable feed performance

Engineered for efficient material removal, the tool achieves a recommended feed performance of 0.09 mm/rev in steel at feed forces up to 500 N, which translates into reliable cycle times and consistent chamfer profiles on repeated operations. The 90° angle is a standard that mates with common countersunk screw profiles, while the cutter’s balanced flute count helps maintain tool life under continuous use. For workshop planners and production engineers, these metrics enable better process planning and fewer interruptions for tool replacement.

Broad material compatibility for workshop versatility

The tool is suitable for countersinking and deburring in steel, cast materials and non‑ferrous metals, making it a versatile choice for mixed production environments. The HSS material provides good toughness and heat resistance for intermittent and steady cutting, ensuring the cutter copes with the thermal and mechanical demands of everyday workshop tasks. Where discrete batches contain different alloys, a single countersink that handles a range of substrates simplifies tooling inventories and speeds changeovers.

Practical integration into existing tooling systems

With its cylinder shank, the countersink fits standard chucks and collets, easing integration into bench drills and machine spindles without special adaptors. Conforming to DIN 335 C means the geometry and dimensions follow recognised industry norms, supporting interchangeability and predictable results when replacing worn cutters. Supplied individually, the tool is ready for immediate use and simple to store as part of a compact tooling kit, aiding workshop efficiency and stock control.

FAQ

Is this countersink suitable for stainless steel?
Stainless steel is a non‑ferrous alloy family with specific machining demands; the TECWERK countersink is designed primarily for steel, cast and non‑ferrous metals—testing on the intended stainless grade is recommended to confirm performance.

What spindle or chuck types accept the tool?
The cylinder shank accepts standard chucks and collets typically used in bench drills and machining centres, enabling straightforward integration of the TECWERK countersink (SKU 2000865156NW).

How does the three‑flute design help in production?
The three‑flute geometry provides more cutting edges and a balanced load, producing a chatter‑free cut that improves surface finish and reduces rework in repetitive countersinking tasks.

Can the tool be used for both countersinking and deburring?
Yes, the geometry and HSS construction make the cutter suitable for producing precision chamfers and for light deburring of drilled holes in the listed materials.

What feed rate should be used for consistent chamfers?
For steel, a feed of around 0.09 mm/rev at feed forces up to 500 N is indicated as a reliable starting point; adjust feed and spindle speed according to machine rigidity and material to optimise finish.
