16.5mm Countersink 90° HSS-Co TiAlN, 3 Unequal Spiral Flutes, Cylindrical Shank, For Steel/Aluminium/Brass/Plastics - TECWERK

Benefit from high‑precision, rattle‑free chamfering thanks to the combination of HSS‑Co construction and TiAlN coating, which delivers long tool life and markedly lower feed and radial forces; order the countersink directly via Metav Werkzeuge or ask our consultants if technical advice is required.

TECWERK Countersink DIN 335C 90° D16.5 mm — HSS‑Co, TiAlN, 3‑flute

The TECWERK Countersink DIN 335C 90° D16.5 mm is a spiral‑fluted, high‑performance countersink designed for precise chamfering and deburring across steel, stainless and heat‑resistant steels, aluminium, brass and plastics

• TiAlN coating for extended tool life
• Spiral flutes for smooth, rattle‑free finishing
• 90° countersink angle for standard chamfers
• Cylindrical shank, right‑hand cut for stable clamping

Consistent, burr‑free chamfers for assembly reliability

The spiralised, unequal convex cutting edges and 90° geometry produce clean, round countersinks that reduce chatter and eliminate burrs, improving part fit‑up and assembly repeatability. Built from HSS‑Co with a TiAlN surface layer, the tool maintains edge integrity under higher temperatures and during longer cycles. This results in fewer reworks and a steadier production flow where precise chamfer quality is essential.

Lower forces and smoother feeds for efficient machining

Optimised cutting geometry reduces thrust and radial loads, with reported reductions of about 60% in feed force and 50% in radial force. Lower cutting forces translate to less tool deflection and reduced strain on fixtures and workholding, enabling faster, more consistent processing. The specified feed parameter for steel — 0.135 mm/rev at up to 800 N — offers a practical starting point for set‑up and helps to balance surface finish with cycle time.

Durable coating and material choices for long service life

The combination of a cobalt‑alloy high‑speed steel substrate and a TiAlN coating gives a reliable toughness‑to‑wear resistance ratio. TiAlN forms a hard, thermally stable layer that resists adhesion and oxidation at elevated cutting temperatures, making the tool suitable for mixed‑material shops and prolonged use. For operations where tool change intervals matter, this construction supports higher productivity with fewer interruptions.

Practical compatibility and secure clamping for workshop use

With a cylindrical shank and right‑hand cutting direction, the countersink is compatible with standard collets and drilling chucks, offering secure clamping for predictable concentricity. The spiral flute design aids chip evacuation during countersinking and deburring in aluminium and plastics as well as ferrous materials. The tool conforms to DIN 335 C (Form C) norms and is particularly suited to production environments requiring repeatable chamfer geometry and minimal manual finishing.

FAQ

Which materials can be processed with this countersink?
The TECWERK countersink is suitable for steel, stainless and heat‑resistant steels, aluminium, brass and various plastics, as stated in the product data.

What is the recommended feed for steels?
A practical reference from the tool data is 0.135 mm per revolution at loads up to 800 N; adjust according to machine rigidity and workpiece material.

How does the TiAlN coating benefit performance?
TiAlN provides thermal stability and reduced adhesion at the cutting edge, extending life under higher speeds and temperatures compared with uncoated high‑speed steel.

Is the shank compatible with common holders?
Yes; the cylindrical shank is suitable for standard collets and chucks, offering stable clamping and concentricity for accurate chamfers.

What is the article number for ordering or referencing?
The article number (SKU) for this countersink is 2000865294NW and the tool is supplied by TECWERK
