End mill DIN 844 Type HR, 12 mm (HSS‑Co5, Weldon shank) by TECWERK

The end mill DIN 844 Type HR, 12 mm (HSS‑Co5) is a short, four‑flute cutter engineered for precision peripheral milling and slotting in steels and cast iron under workshop and light industrial conditions.

• DIN 844 Type HR – high‑precision geometry
• HSS‑Co5 construction, four flutes
• Weldon shank for secure clamping

Consistent geometry for repeatable machining results

The tool’s DIN 844 compliant profile and Type HR specification deliver a predictable cutting geometry that supports repeatable results in series production. The four flutes provide a balance between material removal rate and surface finish, while the centre cut enables plunge starts without pre‑drilling. The 45° chamfer and the relieved, fine cord‑style profile reduce cutting forces and help maintain dimensional stability on short‑reach operations, so setups run reliably across batches.

Hardwearing material and application performance

Manufactured from HSS‑Co5, the cutter combines toughness and hot‑hardness appropriate for demanding steel work. The tool is rated for machining steels up to approximately 800 N/mm² with the uncoated variant and can handle higher strengths when an appropriate coating is applied. Suitability for cast iron is very good, while non‑ferrous metals are conditionally machinable, making the cutter a cost‑effective choice where a single blank can cover a range of tasks without premature wear.

Practical shank design and handling in the workshop

The Weldon shank and the cylindrical body with drive flat ensure secure clamping in common tool holders and reduce the risk of slippage under higher loads. With an overall length of 83 mm and an effective length of 36 mm, the cutter is optimised for short to medium reach operations; the specified cutting length of 4 mm suits narrow slotting and face work. A relief length of 11.5 mm supports chip evacuation and prevents rubbing on extended engagement, simplifying tool selection for typical slotting or peripheral passes.

Clear benefits for production and maintenance

Using a DIN‑specified, cobalt‑alloy high‑speed steel cutter shortens setup time and reduces trial‑and‑error in tool selection. The combination of HSS‑Co5 construction and precise geometry improves wear resistance and maintains edge integrity longer than standard high‑speed grades in tougher steels, resulting in fewer tool changes and more predictable machining cycles. For workshops seeking dependable performance with straightforward tooling logistics, this cutter represents a pragmatic compromise between endurance and cost‑efficiency.

FAQ

What materials is this cutter best suited for?
The TECWERK end mill DIN 844 Type HR, 12 mm (HSS‑Co5) is very well suited for steel and cast iron; non‑ferrous metals are conditionally machinable with this cutter.

Is the tool coated or uncoated?
This cutter is supplied uncoated in the standard configuration; the HSS‑Co5 substrate is specified for improved hot hardness and toughness.

Can the cutter be used for plunge cutting?
Yes, the centre‑cut geometry enables plunge starts and short‑depth slotting without prior drilling, suitable for many short‑run operations.

How does the Weldon shank benefit clamping reliability?
The Weldon shank with drive flat ensures secure axial and torque transmission in standard holders, reducing slippage under load and simplifying tool changes.

What DIN standard does the tool comply with and why is that important?
Compliance with DIN 844 (Type HR) provides standardised geometry and tolerance expectations, supporting predictable results and interchangeability in industrial workflows.
