Slot mill DIN 844 Type N, Ø 14 mm — HSS‑Co8 three‑flute slot cutter (TECWERK)

A Slot mill DIN 844 Type N engineered for milling slots and grooves in workshop and industrial applications, offering centre‑cut capability and a Weldon cylindrical shank for reliable clamping.

• HSS‑Co8 for high wear resistance
• Centre‑cut three‑flute, long version
• Weldon cylindrical shank with drive flat
• Very good for steel and cast iron

Durable cutting core for reliable production results

The cutter combines HSS‑Co8 construction with the DIN 844 Type N geometry to deliver a balance of toughness and edge retention. The three‑flute design reduces vibration and clears chips efficiently, which improves surface finish and extends tool life. As a centre‑cutting tool, the slot mill permits plunge starts and precise groove entry, reducing secondary operations and increasing throughput in repetitive machining tasks. The built quality supports stable performance under continuous use.

Material suitability and practical cutting limits

This tool is specified for use on a wide range of materials: steel and cast iron are rated very good for machining, while non‑ferrous metals and stainless steels are conditionally suitable depending on the application and cutting data. The cutter handles uncoated work up to approximately 800 N/mm² tensile strength, with higher limits—about 1,000 N/mm²—achievable when a suitable coating is applied. Right‑hand cutting geometry ensures predictable chip formation and consistent cutting forces for standard milling setups.

Secure clamping and dimensional reliability

A Weldon shank with the drive flat provides positive torque transmission and repeatable seating in tool holders, while the Ø 12 mm shank diameter matches common collet and arbor systems. Nominal diameter tolerances are specified (small diameters with h10 tolerance, others to e8), supporting concentric mounting and minimal runout. These features together reduce chatter, improve concentricity and protect both spindle and cutter from damage during heavy or interrupted cuts.

Extended reach and workshop advantages

The long version offers increased reach for deeper slots or recessed features without sacrificing rigidity. The specified 11.5 mm free length and the three‑cutting‑edge layout balance accessibility with stability, cutting down on tool changes and setup time. This makes the cutter particularly useful for jobs that require precise, repeatable grooves across batches. Combined with a robust shank connection and centre‑cut capability, the design supports efficient workflow and dependable part quality.

FAQ

What materials is this slot mill best suited for?
The TECWERK slot mill in HSS‑Co8 is rated very good for steel and cast iron; non‑ferrous metals and stainless steel are conditionally suitable depending on cutting data.

Can the cutter be used for plunge milling?
Yes, the centre‑cutting geometry allows plunge starts and controlled entry into the material, which is useful for slot starting without pre‑drilling.

What shank diameter and clamping form does it require?
The cutter has a Ø 12 mm cylindrical shank with a Weldon drive flat, designed for secure clamping in compatible holders and arbors.

Are there specific strength limits for workpieces?
Uncoated tool performance is specified up to around 800 N/mm² tensile strength; with an appropriate coating, the tool can be applied up to roughly 1,000 N/mm².

Does the cutter conform to a standard for dimensions?
The tool follows DIN 844 Type N specifications, with defined tolerances for nominal diameters to ensure repeatable mounting and concentricity.
