6.3mm 120° Countersink HSS 3-Flute Cylindrical Shank, Right-Hand Cutting - TECWERK

Take advantage of a robust HSS design and 3-flute geometry for clean, burr-free chamfering; the conical 120° form limits rework and performs best at lower cutting speeds, while the Ø5 mm shank ensures secure mounting—order directly via Metav Werkzeuge or consult our specialists for application guidance.

TECWERK 120° Conical Countersink Ø6.3 mm, HSS, 3-flute, Shank Ø5 mm

The TECWERK 120° Conical Countersink is a high-speed steel countersink for burr-free chamfering, deburring and spot countersinking across steel, cast parts and non-ferrous light metals.

• HSS, 3-flute conical geometry
• 120° countersink angle
• Cylindrical shank Ø5 mm
• Right-hand cutting for clean edges

Efficient, burr-free chamfering that reduces rework

The TECWERK 120° Conical Countersink combines a 120° cone with a 3-flute layout crafted from HSS to produce consistently burr-free chamfers. This geometry enables a gradual material engagement that lowers cutting forces and minimises edge rollover, reducing the need for secondary operations. The tool is optimised for low cutting speeds; in steel up to 500 N a recommended feed of 0.09 mm/rev gives smooth results and extends tool life, which improves overall process efficiency.

Broad material compatibility to simplify tooling

Designed for use on steel, cast components and non-ferrous metals, the countersink handles a range of workshop tasks from deburring to spot chamfering. The Ø6.3 mm tip diameter provides a defined chamfer size while the cutting-edge geometry copes well with alloys and light metals without tearing. Selecting a lower spindle speed helps control heat and preserves cutting-edge geometry, ensuring consistent surface quality across different materials and reducing scrap rates.

Stable mounting and chip control for reproducible results

A cylindrical shank Ø5 mm offers reliable seating in standard collets and chucks, improving concentricity and reducing vibration. The Form C profile and right-hand cutting direction combine to create smooth chip evacuation and minimize chatter on portable or benchtop machines. This stability supports repeatable chamfer depth and finish, helping to keep cycle times predictable and production flows uninterrupted.

FAQ

What materials is this countersink suitable for?
The TECWERK 120° Conical Countersink is suitable for steel, cast parts and a range of non-ferrous light metals, offering burr-free chamfering across these materials.

What shank size is required for mounting?
A collet or chuck that accepts a Ø5 mm shank is required to mount this countersink securely for consistent concentricity and reduced vibration.

What cutting angle does the tool provide?
The tool features a 120° countersink angle, delivering a standard chamfer profile commonly used for deburring and countersinking applications.

Is there a recommended feed for steel applications?
For steel up to 500 N the recommended feed is 0.09 mm/rev, which balances surface finish and tool life when used at appropriately low cutting speeds.

Can this countersink be used at high spindle speeds?
Best results are achieved at low cutting speed to control heat and preserve edge geometry; high speeds may reduce tool life and compromise finish.
