TECWERK Countersink Set DIN 335 C – 90° | HSS TiN | 6.3–25 mm, 5-piece

TECWERK Countersink Set DIN 335 C – 90° | HSS TiN | 6.3–25 mm, 5-piece is a compact kit for precision countersinking and deburring of drilled holes in production and workshop environments

• DIN 335 C standard for consistent chamfers
• Three cutting edges for smooth surface finish
• Hardened HSS bodies with TiN coating
• Compact plastic case for orderly storage

Consistent chamfers that reduce rework and improve assembly

The kit follows DIN 335 C, providing a standardised 90° countersink geometry that yields reliable, repeatable chamfers. The three-flute design produces a smooth finish that minimises manual deburring, cutting down on secondary operations and rework. With sizes spanning 6.3–25 mm, the set covers common bore diameters used in general fabrication and maintenance. The emphasis here is on predictable results and reduced cycle times, which supports steady throughput on the shop floor.

Durable cutting performance for extended tool life

Constructed from HSS and treated with a TiN coating, the cutters combine toughness with enhanced surface hardness to resist wear. The coating reduces friction at the cutting edge, which helps maintain edge geometry longer and sustains cutting quality across repeated cycles. This translates into fewer tool changes, lower tooling costs over time and more consistent part quality — key considerations for procurement and production planners aiming for efficiency and reliability.

Practical kit to keep the workshop organised

Supplied as a neat 5-piece kit in a plastic case, the set is designed for easy selection and secure storage. Each cutter is sized for rapid identification, supporting quick tool changes and minimal downtime. The compact box fits on a tool trolley or in a workstation drawer, making it straightforward to keep countersinks at hand for both on-the-spot repairs and planned machining operations.

Simple integration with standard drilling workflows

The cutters are intended to be used after drilling operations, pairing well with a standard twist drill to finish the bore. The tool geometry and flute count favour smooth chip evacuation during countersinking, helping to avoid edge break-out and ensuring a clean chamfer ready for fastening or surface treatment. For teams seeking predictable assembly fit and finish, this set provides a practical, standards-based solution.

FAQ

What sizes are included in the set?
The TECWERK countersink set contains cutters covering the 6.3–25 mm range to match common drilled-hole diameters.

What is the countersink angle and why does it matter?
A 90° countersink angle is used for standard chamfers and screw seating; the set’s compliance with DIN 335 C ensures consistent angle control for repeatable assembly results.

What material and coating are used on the cutters?
The cutters are made from HSS and feature a TiN coating, which enhances wear resistance and helps prolong tool life under regular use.

Can these countersinks be used directly after drilling with a twist drill?
Yes, the cutters are intended to be used following drilling with a twist drill to finish the bore and remove burrs, improving fit and surface preparation.

Is the kit suitable for workshop storage and mobile use?
The set is supplied in a compact plastic case for secure storage and easy transport between workstations.
