8.3mm Countersink 90° HSS 3-Flute Cylindrical Shank, Smooth Cutting - TECWERK

Take advantage of a robust combination of HSS construction, DIN 335 C compliance and a 90° cutting angle for precise countersinking and fast deburring. Order the cutter directly via Metav Werkzeuge or consult the team for process recommendations.

TECWERK Countersink DIN 335C 90° D8.3 HSS — 3‑flute cylindrical shank

A TECWERK Countersink DIN 335C 90° D8.3 designed for clean countersinking and deburring of drilled holes in steels, cast materials and non‑ferrous metals.

• High-speed steel HSS, DIN 335 C standard
• 90° countersink angle for standard chamfers
• Three cutting edges for chatter‑free cutting
• Cylindrical shank for secure clamping

Consistent chamfers that reduce rework

The HSS construction and conformity with DIN 335 C ensure durable cutting geometry that maintains edge integrity under repeated use. With a 90° angle and an 8.3 mm diameter, the tool is tailored for standard chamfers and allows uninterrupted production runs. The predictable geometry minimises the need for manual finishing, so chamfer quality is consistent and component throughput is improved.

Smooth cutting and reliable surface finish across materials

Equipped with three cutting edges, the countersink delivers a chatter‑free cut that reduces vibration and produces a cleaner surface around the bore. Suitable for steel, cast iron and non‑ferrous metals, the cutter handles deburring and countersinking tasks without aggressive radial forces. The balanced cutting action lowers the risk of burr formation and supports repeatable results in mixed‑material batches.

Secure mounting and measurable feed parameters for process control

A cylindrical shank guarantees firm clamping in standard tool holders, providing stable concentricity during rotation. For process planning, a feed in steel up to 500 N can be applied at 0.09 mm/rev, giving a reference for cycle time calculations and machine setup. The tool is primarily intended for countersinking and deburring operations; parameter adjustments can be made according to hole diameter and material hardness to optimise performance.

FAQ

What materials can be processed with this countersink?
The TECWERK countersink is suitable for steel, cast iron and non‑ferrous metals, covering common workshop and production tasks where clean chamfers and deburring are required.

What cutting angle does the tool have and what does that mean?
The tool has a 90° countersink angle; this standard angle produces conventional chamfers for countersunk fasteners and is compatible with typical assembly requirements.

How many flutes does the cutter have and what is the advantage?
With three cutting edges, the cutter provides a balanced, chatter‑free cut that improves surface finish and reduces vibration during countersinking.

Is there a recommended feed rate for steel?
A reference feed in steel up to 500 N is 0.09 mm/rev, which can be used as a starting point for process setup and optimisation.

Which standard does the tool conform to?
The cutter is specified to DIN 335 C, indicating dimensions and profile in line with industry countersink standards.
