90° Countersink DIN 335C, D 6.3 mm, HSS Nano — TECWERK

The 90° Countersink DIN 335C, D 6.3 mm HSS Nano is a high-performance three-flute countersink designed for fast, low-force chamfering and deburring across a wide range of metals and plastics

• HSS with Nano coating for high wear resistance
• 90° angle for standardised chamfering
• Three cutting edges for smooth, quiet operation
• Reduced feed force and up to 60% longer life

High efficiency through optimised geometry and coating

The tool combines a HSS substrate with a specialised Nano-coating and carefully tuned chipspace parameters to reduce friction and heat buildup during countersinking. This results in a reduced feed force, smoother tool engagement and measurable productivity gains: the design supports up to 60% longer tool life and can achieve up to 30% faster countersinking under compatible conditions. For production environments, these gains mean fewer tool changes and more consistent cycle times, supporting a reliable machining flow.

Consistent chamfers with quiet, stable running

Built to the DIN 335 C form with three cutting edges, the cutter provides an extremely smooth, quiet run and improved surface finish compared with two-flute alternatives. The combination of right-hand cutting, a variable relief, and a well-sized chip room ensures controlled chip formation and minimised vibration. These characteristics help maintain drilling accuracy and deliver repeatable chamfer geometry on series parts, reducing rework and inspection effort.

Broad material capability for workshop versatility

The countersink is suitable for machining a variety of materials, including steel, stainless and heat-resistant steels, aluminium, brass and plastics, making it a versatile choice for mixed-production shops. The tool’s material compatibility and thermal stability from the coating preserve cutting edges longer when working harder alloys, while still offering clean results on softer metals and engineering plastics. This flexibility allows consolidation of tooling stock without compromising performance.

Practical handling and operating guidance

Key practical features include a cylindrical shank with three clamping flats (applicable from nominal Ø 8.3 mm), right-hand cutting direction and optimised relief geometry for reliable chip evacuation. The specified operating guideline indicates a feed in steel up to 800 N: 0.15 mm/rev, which helps to balance tool life and surface quality. The cutter’s design reduces the required thrust during entry, easing use on handheld or machine-mounted countersinking operations and lowering mechanical stress on fixtures.

FAQ

What materials can this countersink process reliably?
The countersink is specified for steel, stainless and heat-resistant steels, aluminium, brass and plastics, so the TECWERK 90° countersink suits mixed-workshop applications where a single tool must handle varied substrates.

What operating feed is recommended for steel?
The product data states a guideline of 0.15 mm/rev for operation in steel at up to 800 N, a parameter intended to balance tool life and surface finish under typical countersinking loads.

What benefits does the Nano coating provide?
The Nano coating increases wear resistance and hot hardness, promoting longer tool life and more consistent chamfer quality under elevated temperatures and higher cutting forces.

Is the cutter compatible with standard machine holders and fixtures?
Yes, the cutter follows DIN 335 C form and features a cylindrical shank; from nominal Ø 8.3 mm it comes with three clamping flats to ensure secure clamping in standard holders.

How does the three-flute design affect performance?
The three cutting edges deliver steadier cutting forces, improved surface finish and a notably smoother, quieter run compared with two-edge designs, supporting higher feed rates and reduced vibration.
