20mm Drill Slot Cutter HSS‑Co8 3‑Flute Short, 19mm Relief, Right‑Hand Cut, DIN 327 - TECWERK

Combining HSS‑Co8 construction, a DIN 327 Type N three‑flute short design and a Weldon shank, this cutter delivers precise and repeatable keyway milling with secure clamping and high wear resistance; order directly via Metav Werkzeuge or consult the technical advisors for application guidance.

TECWERK keyway cutter DIN 327 Type N — 20 mm, HSS‑Co8, Weldon shank, 3‑flute (short)

A TECWERK keyway cutter DIN 327 Type N engineered for accurate slot and keyway milling in steel and cast iron, featuring centre‑cutting geometry and a Weldon shank for dependable tool holding.

• HSS‑Co8 high‑cobalt steel for heat resistance
• DIN 327 Type N three‑flute short design
• Weldon shank with drive flat for secure mounting
• Suitable for steel and cast iron up to ~800 N/mm²

Precision and cycle‑time gains from a centre‑cutting design

The short, centre‑cutting three‑flute geometry provides safe plunge capability and steady axial engagement, translating into shorter machining cycles and consistent slot profiles. Built from HSS‑Co8, the cutter combines toughness with improved hot‑hardness compared with conventional high‑speed steels, which supports higher cutting speeds and reduced wear in serial production. The adherence to DIN 327 guarantees dimensional consistency for repeat setups across different machines, aiding process reliability and first‑pass right manufacturing.

Material suitability and machining advantages

The tool is specified for materials with low to medium tensile strength; the uncoated configuration is effective up to around 800 N/mm², with coated tools extending serviceable range to about 1000 N/mm². Performance is rated very good on steel and cast iron, and conditional on stainless and non‑ferrous alloys; this supports versatile use in workshops that process mixed batches. The combination of a short flute length and cobalt‑alloyed steel reduces chipping risk during interrupted cuts, delivering cleaner keyways and fewer rework cycles.

Secure clamping and handling for repeatable results

A Weldon shank with drive flat and a matching shank diameter of 20 mm provide positive drive and reduced slippage in the tool holder, which is particularly valuable when machining deep keyways or during higher torque passes. The cutter’s effective length of 36 mm and a relief length of 19 mm ensure stable axial support while limiting overhang; this lowers vibration and improves surface finish on both flank and face. The right‑hand cutting direction and three cutting edges balance material removal rate with surface integrity, simplifying toolpath planning for CAM programmes.

Supply reliability and shopfloor confidence

Supplied by a trusted industrial partner, this short slot cutter suits production and maintenance environments seeking durable, ready‑to‑fit tooling with standardised dimensions for quick tool changes. The compact design reduces storage complexity and the Weldon interface supports rapid replacements without additional adaptors. Metav’s distribution combines broad product range and expert advice, helping to integrate this cutter into established machining processes with transparent availability information and straightforward logistics.

FAQ

What materials can this keyway cutter machine effectively?
The cutter is designed for low to medium strength materials; it is very good on steel and cast iron and conditionally suitable for stainless steel and non‑ferrous metals, as described for the TECWERK keyway cutter.

Is the cutter suitable for plunge milling and slotting operations?
Yes, the centre‑cutting geometry enables safe plunge milling and axial engagement, so the slot milling cutter can be used for both face and peripheral milling of keyways.

What clamping interface is provided and why does it matter?
The tool features a Weldon shank with drive flat, ensuring secure positive drive in the toolholder and reducing slippage during high‑torque passes.

How many cutting edges does the tool have and what is the benefit?
The cutter has three cutting edges (three‑flute), which balance material removal rate and surface finish while offering stable cutting forces for repeatable results.

Can this cutter be used at higher cutting speeds?
Constructed from HSS‑Co8, the tool tolerates higher cutting temperatures than standard HSS, allowing elevated cutting speeds and extended tool life in many steel‑machining scenarios.
