TECWERK 90° Countersink DIN 335C Ø8 mm HSS, 3 flutes

The TECWERK 90° Countersink DIN 335C Ø8 mm HSS, 3 flutes is a precision chamfering tool for countersinking and deburring holes in steel, cast parts and non‑ferrous metals

• HSS material, DIN 335C conformity
• Three cutting edges for rattle‑free cutting
• 90° countersink angle for standard chamfers
• Cylindrical shank for secure clamping

Precision results with robust HSS construction

The HSS composition and DIN 335C specification ensure consistent performance in industrial workshops. The tool’s hardened high‑speed steel retains edge geometry under heat and load, delivering repeatable chamfers and clean deburred edges. This reliability translates into fewer reworks and less tool change downtime, increasing throughput in small and medium‑scale production environments. The combination of standard compliance and material quality supports predictable process planning and component interchangeability.

Smooth cutting and accurate feed control

Equipped with three cutting edges, the countersink produces a rattle‑free, balanced cut that reduces chatter and improves surface finish. The geometry permits a controlled feed: in steel, the tool is specified for a feed of 0.09 mm/rev at a clamping force reference up to 500 N, which helps operators match machining parameters to material and machine capability. The 90° angle creates standard chamfers for bolt seating and deburring tasks, while the cylindrical shank allows straightforward mounting in conventional drill chucks and holders.

Versatile application and workflow benefits

Designed for chamfering and deburring holes in steel, cast materials and non‑ferrous metals, the tool integrates into general workshop and production cells where economical, precise finishing is required. The three‑flute design speeds chip removal and reduces re‑cutting, supporting cleaner hole edges and improved assembly fit. When paired with a stable clamping setup, the countersink offers long tool life and consistent edge quality, making it suitable for both occasional maintenance work and repetitive production routines.

FAQ

What materials can this countersink process?
The TECWERK 90° countersink is designed for use on steel, cast materials and non‑ferrous metals, offering clean chamfers and efficient deburring in typical workshop applications.

How does the three‑flute design affect performance?
Three cutting edges provide a balanced, rattle‑free cut that improves surface finish and chip evacuation compared with two‑flute variants, reducing vibration and enhancing chamfer quality.

What feed should be used in steel?
For machining steel with the TECWERK countersink, a reference feed of 0.09 mm per revolution is indicated at a clamping condition up to 500 N to maintain stable cutting and finish.
