Countersink 75° Ø8.3 mm HSS — 3‑flute, 6 mm shank | TECWERK

The Countersink 75° Ø8.3 mm HSS is a precision countersinking tool designed for burr‑free chamfering, deburring and spot countersinking across steels, cast materials and non‑ferrous metals.

• HSS construction for high wear resistance
• 75° angle for standard, precise chamfers
• 3 flutes for smooth, burr‑reduced cutting
• 6 mm cylindrical shank for secure mounting

Consistent, burr‑free finish for demanding workpieces

Built from high‑speed steel (HSS) and manufactured in Form C with three cutting edges, this countersink produces consistent chamfers and reduces rework. The 75° geometry is a standard angle for countersinking and creates reliable seatings for fasteners and rivets. Right‑hand cutting and the three‑flute design combine to give a burr‑reduced finish, while the tool’s construction favours best results at low cutting speed, helping to preserve edge life and maintain surface integrity on hardened or thin materials.

Stable mounting and predictable machining parameters

A 6 mm cylindrical shank ensures stable clamping in standard collets or chucks, reducing run‑out and vibration during operation. The tool’s specified feed in steel — 0.09 mm/rev at up to 500 N — provides a practical guideline for setting up machining cycles: at these parameters the cutter achieves smooth material removal and a controlled cutting force. The right‑hand cut orientation simplifies integration into existing production routines and reduces the need for specialised cycle programming.

Versatile application across common workshop materials

This countersink is engineered for burr‑free countersinking, deburring and spot chamfering in steel, cast iron, non‑ferrous and light metals, making it suitable for general workshop and maintenance tasks as well as production use. The tool’s HSS composition balances toughness and edge retention, offering good service life in intermittent operations and where low cutting speeds are preferred. For operations that demand a clean finish without secondary deburring, the cutter delivers a practical efficiency gain and improves downstream assembly quality.

FAQ

Which materials can be processed with this countersink?
The countersink is suitable for steel, cast iron, non‑ferrous and light metals, delivering burr‑reduced results for chamfering and deburring tasks.

What are the tool’s main dimensions and mounting details?
The cutter has a diameter of 8.3 mm and a 6 mm cylindrical shank for secure mounting; the SKU is 2000865132NW for reference.

How many flutes does the tool have and what advantage do they provide?
With three flutes, the tool reduces chatter and produces a smoother, burr‑reduced finish compared with two‑flute designs.

Which cutting parameters are recommended for steel workpieces?
A practical feed guideline is 0.09 mm/rev in steel up to 500 N, with best results achieved at low cutting speeds to extend edge life.

Is the tool suited for precision assembly prep and countersunk fasteners?
Yes — the 75° countersink geometry is ideal for creating standard seats for fasteners and provides consistent seating for assembly operations.
