TECWERK Countersink DIN 335C 90° D 8.3 mm HSS — overlong, 3‑flute

TECWERK Countersink DIN 335C 90° D 8.3 mm HSS for reliable countersinking and deburring of through‑holes in steels, cast iron and non‑ferrous metals with an overlong cylindrical shank for deep operations

• HSS construction for robust cutting
• 90° countersink angle for standard seating
• Three‑flute design for rattle‑free cuts
• Overlong cylindrical shank for deep bores

Accurate seating and fewer reworks with standard geometry

The combination of HSS material and the DIN 335C geometry ensures a predictable cutting behaviour and long service life in routine production work. The 90° angle is the recognised standard for creating screw seatings and chamfers that match typical fastener heads, reducing the need for manual finishing. This geometry provides a defined contact surface, which leads to more consistent torque and joint integrity when fasteners are installed. For workshops and small series production, this means fewer rejects and less rework, improving throughput without complex process changes.

Smooth, rattle‑free cutting for improved surface quality

Thanks to the three‑flute arrangement the tool produces a rattle‑free cut, which reduces vibration and enhances surface finish at the countersink. Fewer vibrations also lower tool wear and help maintain concentricity when working in handheld or less rigid setups. The flute design aids chip formation and evacuation, keeping the cutting edges cleaner for longer and delivering a neater bore entrance — a particular advantage when preparing holes for precision assemblies or plated components.

Reach deeper bores with the overlong cylindrical shank

The overlong design with a cylindrical shank enables reliable access to recessed or deep holes without the need for extensions or multiple tool changes. The extended reach helps maintain process continuity on components with countersunk features located well inside assemblies or jigs. Stable clamping of the shank in standard collets or chucks preserves concentricity and reduces run‑out, so the countersink produces uniform results even at depth.

Suitable for a wide range of materials with controlled feed rates

The countersink is specified for use on steel, cast iron and non‑ferrous metals, making it suitable for diverse workshop tasks from mechanical maintenance to light production runs. The tool is optimised for feeds up to 0.09 mm/rev in steel at moderate cutting forces (up to 500 N), which balances material removal with surface quality; for softer non‑ferrous alloys slightly higher feeds are possible, while harder materials require conservative feed and steady spindle speed. This specification helps planners and operators set reliable machining parameters without guesswork.

FAQ

What materials can this countersink be used on?
The TECWERK countersink (DIN 335C, SKU 2000865397NW) is suitable for steel, cast iron and non‑ferrous metals, providing reliable deburring and seating in common workshop materials.

What does the three‑flute design deliver in practice?
A three‑flute arrangement produces a rattle‑free cut with improved surface finish and better chip formation, which helps maintain edge life and reduce vibrations during countersinking.

How deep can the tool reach compared with standard countersinks?
The overlong cylindrical shank allows access to deeper or recessed holes than standard countersinks, reducing the need for tool extensions or additional setups.

Which feed should be used for steel?
The tool specification lists a feed of 0.09 mm/rev for steel under cutting forces up to 500 N; this provides a balance between finish and productivity and can be adjusted slightly for softer or harder materials.
