TECWERK Countersink DIN 335C Ø4.3 mm — HSS, 3 flutes, 90°

A TECWERK HSS countersink for precision countersinking and deburring of holes in steel, cast iron and non‑ferrous metals

• HSS construction for high wear resistance
• 90° countersink angle for standard chamfers
• Three flutes for chatter‑free cutting
• Cylindrical shank for conventional toolholders

Consistent chamfers that improve assembly quality

The 90° countersink geometry produces standard chamfers for reliable screw seating and clean edge preparation. Made of HSS, the tool maintains cutting integrity under typical workshop loads and offers predictable tool life. The specification DIN 335 C denotes the standardised form and tolerances, making the component easy to replace and integrate in industrial workflows. As a result, users benefit from improved part fit and reduced rework during assembly.

Faster, smoother cutting with reduced surface defects

Equipped with three flutes, the design delivers a chatter‑free cutting action that lowers the risk of vibration marks and burnishing on hole edges. The flute geometry spreads the cutting forces, enabling a steady feed — measured here as 0.07 mm/rev at a feed force up to 500 N in steel — which helps to maintain cycle‑time predictability. In practice, this means fewer rejects and a smoother production process when countersinking or deburring holes before final finishing or coating.

Straightforward fitting and versatile material use

The cylindrical shank fits common drill chucks and toolholders for easy mounting, allowing quick tool changes during busy shifts. The cutter is specified for use on steel, cast iron and non‑ferrous metals, offering one‑tool versatility across typical workshop substrates. The three‑cutting‑edge concept also supports controlled burr formation, simplifying downstream finishing. For shops consolidating tooling, this countersink reduces the need for multiple specialised deburring tools.

Practical guidance for workshop integration

The tool’s standardised form and robust HSS composition make it suitable for routine maintenance and production tasks where dependable chamfers are required. When selecting cutting speeds and feeds, adhere to material‑specific recommendations and the stated feed rate as a starting point to balance surface quality and tool life.
