TECWERK Countersink Set DIN 335 C – HSS TiAlN, 90°

The TECWERK Countersink Set DIN 335 C is a workshop-grade countersinking solution designed for clean countersinking and deburring of drilled holes in metalworking and maintenance environments.

• DIN 335 C, 3-flute geometry
• 90° countersink angle for standard screws
• HSS with TiAlN coating for longer life
• Supplied in a durable plastic storage box

Consistent seatings through proven geometry

The cutters follow DIN 335 C with a 3-flute design and a 90° chamfer angle, delivering repeatable, flat-bottomed seats for standard fasteners. The three cutting edges balance chip formation and contact area, which reduces chatter and improves surface finish compared with two-flute variants. This geometric choice translates into fewer rejected parts and less time spent on manual rework, supporting steady production quality in everyday workshop operations.

Extended lifespan and higher cutting performance

Manufactured from HSS and finished with TiAlN, the tools combine toughness with increased heat resistance. The coating raises thermal stability and reduces abrasive wear, allowing higher cutting speeds and longer intervals between tool changes. As a result, the set sustains cutting performance during repeated operations, improving uptime and lowering total tooling consumption for routine countersinking tasks in industrial and service-shop settings.

Organised kit for efficient workshop use

The set arrives in a dedicated plastic box that keeps each cutter accessible and protected. Clear organisation minimises search time at the bench and reduces handling-related damage during storage. The compact storage solution supports mobile toolkits, service vans and bench drawers alike, helping to maintain a tidy workspace and to speed up job preparation and tool changes on site.

Practical coverage for common hole sizes

Covering a practical diameter range, the cutters enable accurate deburring and chamfering across multiple hole sizes while adhering to the DIN standard for countersinks. The set’s consistent cutting geometry and coating ensure uniform chamfer edges without excessive material removal, which preserves component tolerances and avoids weakening fastener seats. This makes the kit suitable for routine assembly prep and maintenance tasks where consistent, standardised countersinks are required.

FAQ

What angle do the countersinks have?
The set uses a 90° countersink angle, which is specified for flat countersinking and seating of standard fasteners with the TECWERK Countersink Set (SKU 2000865219NW).

How does the TiAlN coating benefit the cutters?
The TiAlN coating increases surface hardness and heat resistance on the HSS cutters, reducing wear and permitting higher cutting speeds during repeated countersinking operations.

Which cutting geometry is used and why?
A 3-flute geometry according to DIN 335 C is employed to balance chip evacuation and cutting contact, resulting in smoother chamfers and reduced vibration compared with fewer-flute designs.

Is a storage solution included with the set?
Yes, the set is supplied in a durable plastic box to keep the cutters organised, protected and quickly available for workshop use.

What is included in the set?
The kit contains five HSS countersinks with TiAlN coating, covering a diameter range of 6.3–25 mm with a 90° angle, compliant with DIN 335 C for reliable countersinking
