Flat countersink DIN 373 M10 (HSS) – TECWERK, 180°

A Flat countersink DIN 373 M10 engineered for burr-free recesses for cylinder head screws, hex bolts and nuts across steel, cast iron and non-ferrous metals.

• HSS construction for long tool life
• 180° angle for flat, precise recesses
• Three cutting edges for smooth surface finish
• Cylindrical shank with fixed pilot for guidance

High-precision countersinking that reduces rework

The countersink is made from HSS, offering a good balance between toughness and wear resistance for everyday workshop use. With three cutting edges and a 180° geometry, the tool produces a flat seating surface that significantly reduces burr formation and secondary deburring. The specified feed of 0.2 mm/rev in steel and the recommendation for low cutting speeds ensure stable chip formation and consistent results, making the tool suitable for production runs where repeatability is essential.

Robust design for reliable workshop operation

Built with a cylindrical shank and a fixed pilot, this countersinking tool maintains concentricity and prevents wandering during through-hole operations. The medium grade tailored for through holes balances cost and performance, delivering burr-free and chatter-free countersinks in both ferrous and non-ferrous materials. The sturdy design minimises tool change frequency and helps maintain cycle-time stability on manual and CNC machines alike.

Practical use and integration into production workflows

This countersink is intended for creating recesses for cylinder head screws, hex bolts and nuts and achieves the best results at moderate cutting parameters. For raised efficiency, use the tool immediately after drilling a through hole and avoid excessive spindle speeds to preserve the cutting edge. The construction supports reliable countersinking in cast iron and aluminium alloys, reducing the need for downstream finishing and improving overall process economics.

FAQ

What materials can be processed with this countersink?
The TECWERK Flat countersink DIN 373 M10 is suitable for steel, cast iron and various non-ferrous alloys; it delivers best results when used at lower cutting speeds.

How many cutting edges does the tool have and why does that matter?
The tool has three cutting edges; this geometry improves surface finish and reduces chatter compared with two-edged designs, giving a smoother, burr-reduced recess.

Is the countersink suitable for through-hole countersinking?
Yes, the medium grade is specified for through-hole use and the fixed pilot ensures guided entry and concentricity in through-hole countersinking.

What feed and speed settings are recommended for steel?
A feed of around 0.2 mm/rev in steel (up to 500 N) is recommended, combined with modest spindle speeds to preserve edge life and produce clean chips.

Which fasteners is this countersink designed for?
This countersink is intended for creating recesses for cylinder head screws, hex bolts and nuts; the 180° angle produces a flat seating surface suitable for those head forms.
