Countersink DIN 335 C Ø 8.3 mm — 90° HSS TiAlN, 3‑flute (TECWERK)

A Countersink DIN 335 C Ø 8.3 mm for chamfering and deburring holes in steel, castings and non‑ferrous materials, supplied with a cylindrical shank for secure mounting.

• DIN 335 C standardised 90° countersink
• 3-flute design for chatter-free cutting
• TiAlN coating for enhanced wear resistance

Faster, more reliable chamfering with measurable performance

The 3‑flute geometry delivers a chatter‑free cut, reducing vibration and improving surface finish compared with two‑flute designs. This results in fewer reworks and a more predictable process time per hole. The tool meets DIN 335 C specifications and is optimised for a feed of 0.09 mm/rev in steel up to 500 N, giving a clear, verifiable baseline for program setup and cycle time calculations. These measurable values support production planning and help maintain throughput.

Reduced tool wear and longer life for lower operating costs

The TiAlN coating provides superior heat resistance and lubricity compared with uncoated high‑speed steel, extending tool life in intermittent and continuous chamfering operations. Because the substrate is HSS, the tool combines toughness with the coating’s thermal protection, making it suitable for routine use on steel, cast iron and non‑ferrous metals. Longer tool life reduces tooling change frequency and downtime, contributing to a lower total cost of ownership in workshop and light industrial settings.

Secure handling and consistent results on standard spindles

A cylindrical shank ensures a straightforward fit in standard collets and chucks, while the balanced three‑cutter design keeps runout low for repeatable chamfer geometry. The result is uniform countersinks and deburred edges, facilitating faster assembly and better joint quality for subsequent operations such as fastening or sealing. The standardised shank and form make the tool easy to integrate into existing setups without special holders.

Clear guidance for users with varied experience levels

Technical terms are kept simple: HSS denotes high‑speed steel, valued for toughness; TiAlN is a titanium aluminium nitride coating that protects the cutting edge at higher temperatures; DIN 335 C defines the 90° countersink form. These definitions help technicians and purchasers understand why the tool performs as it does and how to match machining parameters to material hardness and machine capability. The documented feed recommendation provides an immediate starting point for process trials.

Versatile use across common workshop materials

Designed primarily for chamfering and deburring, the tool is suitable for through holes and blind holes in typical workshop materials. The combination of three cutting edges, the 90° angle and the TiAlN finish supports clean deburring on cast components and non‑ferrous parts while maintaining edge integrity on mild and medium alloy steels. For applications requiring higher temperature or corrosion resistance machining, consider HSS‑Co grades or alternative tool chemistries as appropriate.

FAQ

What materials is this countersink suitable for?
The TECWERK countersink (DIN 335 C, Ø 8.3 mm, SKU 2000865223NW) is suitable for steel, castings and non‑ferrous metals, as indicated by its HSS substrate and TiAlN coating.

Can this tool be used in a handheld drill or only in machine spindles?
The cylindrical shank allows mounting in common collets and chucks; while bench and machine spindles provide the most consistent results, the countersink can be used in suitable handheld drills if runout and feed are controlled.

How does the TiAlN coating affect performance?
TiAlN increases heat resistance and edge life under higher temperatures, so the coated countersink maintains cutting performance longer than an uncoated HSS cutter in continuous chamfering tasks.

Is the 0.09 mm/rev feed a strict requirement?
The specified feed of 0.09 mm/rev for steel up to 500 N is a recommended starting value for reliable cutting; adjustments may be made based on machine rigidity and workpiece clamping.

What advantage does the three‑flute design offer over two flutes?
Three flutes deliver a steadier cut with reduced vibration, resulting in a chatter‑free finish and more uniform chamfer geometry for repeatable assembly quality.
