Kegelsenker 120° Ø8.3 mm HSS, 3‑flute, 6 mm shank — TECWERK

A Kegelsenker 120° Ø8.3 mm HSS, 3‑flute, 6 mm shank designed for precise deburring, countersinking and recessed seating in steel, cast iron and non‑ferrous alloys for workshop and light industrial use

• HSS, Form C for smooth cuts
• 120° countersink angle for universal seating
• 3 cutting edges for burr-free finishing
• 6 mm cylindrical shank for standard toolholders

Consistent, burr‑free finishing for repeatable results

The HSS construction and Form C geometry deliver a balance of toughness and edge retention, enabling clean material removal with minimal burring. The 3‑flute design distributes cutting forces evenly, producing a uniform chamfer and reduced vibration compared with two‑flute countersinks. For routine workshop tasks this means fewer reworks and a stable surface quality across batches, particularly when machining mild to medium‑strength materials such as steel, cast iron and non‑ferrous metals. The tool’s right‑hand cutting action promotes controlled chip evacuation for a cleaner hole edge.

Simple fitting and compatibility with standard holders

Fitted with a 6 mm shank in cylindrical format, the cutter seats reliably in common collets and drill chucks used on benchtop drilling machines and portable units. The 120° tip angle is a widespread standard for screw seating and countersink operations, which eases tool selection for mixed workflows. This compatibility reduces setup time and supports lean production: a single tool handles deburring, countersinking and seat preparation without frequent tool changes. The cutter’s configuration is particularly favourable when aiming for burr‑free recesses in manual and semi‑automated cells.

Optimised cutting data for efficient machining

The geometry provides stable cutting at modest speeds; best results are achieved at lower cutting speeds with steady feed. A recommended reference is the specified feed in steel of 0.09 mm/rev (up to the referenced cutting resistance), which supports a controlled material removal rate while avoiding thermal overload of the HSS substrate. The three cutting edges offer a greater effective cutting perimeter, which contributes to a smoother finish and can increase tool life under appropriate cutting conditions. This technical balance makes the tool a cost‑effective choice where surface integrity is essential.

Practical handling and maintenance for workshop use

Careful handling and routine inspection keep the countersink performing predictably: monitor edge condition and regrind when the clearance or cutting profile dulls. The solid HSS body allows re‑sharpening on conventional grinding equipment, extending service life and lowering total cost of ownership. For mixed‑material shops the right‑hand cutting action and flute geometry reduce the incidence of built‑up edge, especially when deburring soft aluminium alloys. For unfamiliar applications, consultation with Metav Werkzeuge’s technical advisers helps select optimum speeds and feeds for the material at hand.

FAQ

Which materials is this countersink suitable for?
The Kegelsenker 120° Ø8.3 mm HSS, 3‑flute, 6 mm shank is designed for use in steel, cast iron and common non‑ferrous and light metals, delivering clean seats and effective deburring.

What is the recommended feed and why does it matter?
A reference feed in steel of 0.09 mm/rev is indicated for stable cutting and minimal burring; following this guideline helps the TECWERK countersink preserve edge life and ensure consistent surface quality.

Will the 6 mm shank fit standard chucks and collets?
Yes — the 6 mm cylindrical shank is compatible with typical collets and drill chucks used in workshop and light production environments, making the tool straightforward to integrate.

Can the HSS countersink be re‑sharpened?
The HSS material of this countersink permits re‑sharpening on suitable grinding equipment, which can extend service life and reduce lifetime tooling costs.

What distinguishes Form C geometry in practice?
Form C provides a stable cutting profile with balanced rake and clearance angles, which improves surface finish and reduces the tendency to form burrs compared with more aggressive geometries.
