3mm Keyway Milling Cutter HSS-Co8 3-Flute Short 49mm Overall, DIN 327 - TECWERK

Take advantage of the combination of HSS‑Co8 hardness, a three‑flute geometry and a secure 6 mm Weldon shank for reliable keyway and slot machining; order the slot milling cutter directly via Metav Werkzeuge or ask our consultants if needed.

Slot milling cutter DIN 327 Type N, 3 mm – short, HSS‑Co8 by TECWERK

A Slot milling cutter DIN 327 Type N, 3 mm engineered for precise keyway and slot milling in steel and cast iron, suited to both face and peripheral cutting.

• HSS‑Co8 construction for long tool life
• Three‑flute design for stable cutting
• 6 mm Weldon shank for secure clamping

Precision and performance for demanding slot machining

The short slot milling cutter is made from HSS‑Co8, delivering a balance of toughness and wear resistance that benefits repetitive production tasks. The three‑flute geometry reduces vibration and improves chip removal on narrow slots, while the centre cutting capability allows plunge entry for accurate keyway starts. Specified to DIN 327, the tool supports machining of materials with low to medium strength up to approximately 800 N/mm² with an uncoated cutter and up to 1000 N/mm² when a coating is applied, offering clarity on expected performance in mixed production environments.

Reduced setup time and repeatable results on keyways

A 6 mm shank with a drive flat (Weldon) ensures secure clamping in standard collets and tool holders, lowering the risk of slippage during peripheral milling and deep keyway cuts. The compact overall length reduces deflection in tight fixturing, increasing precision and surface finish consistency. The right‑hand cutting direction and dedicated short profile mean faster indexing and less need for rework, translating into measurable productivity gains on small‑bore and compact components.

Versatility in workshop applications with clear material guidance

Designed specifically for keyway and slot operations, the cutter performs very well on steel and cast iron and is conditionally suitable for non‑ferrous metals and some stainless steels. The tool’s geometry is optimised for both face and peripheral milling of deeper keyways, giving a straightforward solution where a repeatable slot profile is required. Where material hardness approaches the upper guidance, consider a coated variant to extend service life; the manufacture’s specifications indicate the limits and help plan maintenance intervals for uninterrupted production.

FAQ

What materials is this slot milling cutter suitable for?
The slot milling cutter (TECWERK, DIN 327 Type N, SKU 2000866176NW) is specified as very good for steel and cast iron, and conditionally suitable for non‑ferrous metals and some stainless steels.

Can this cutter be used for plunge machining?
Yes, the centre cutting geometry allows plunge entries for accurate keyway starts, enabling both face and peripheral milling operations.

What clamping system is recommended for secure holding?
A 6 mm shank with a drive flat (Weldon) is provided for secure clamping in standard collets and Weldon‑style tool holders, improving repeatability during production runs.

Is the tool suited to high‑hardness steels?
The tool is designed for low to medium strength materials up to around 800 N/mm² uncoated; for higher strengths up to 1000 N/mm², a coated variant is recommended to increase tool life.

How many cutting edges does the cutter have and what advantage does that give?
The three‑flute configuration delivers stable cutting with improved chip evacuation and reduced vibration compared with fewer‑flute designs.
