TECWERK HSS‑Co5 end mill (DIN 844) — 16 mm, 42 mm effective length

The TECWERK HSS‑Co5 end mill for general machining offers a short Type HR design with a Weldon shank and centre-cut geometry, suited to machining steel and cast iron in demanding workshop and production environments

• HSS‑Co5 for enhanced heat resistance and toughness
• Four‑flute geometry for smooth finishing and chip control
• Weldon shank with drive flat for secure clamping
• Centre‑cutting for plunge and slotting operations

Reliable cutting performance for steels and cast components

The short Type HR geometry, manufactured from HSS‑Co5, is designed to maintain cutting strength at elevated temperatures, which directly benefits tool life and process stability when machining medium‑strength steels. Conformity to DIN 844 ensures repeatable dimensions and predictable performance across batches. The combination of cobalt‑alloyed high‑speed steel and a four‑cutting‑edge layout delivers a balanced trade‑off between wear resistance and edge toughness, making this tool a dependable choice where consistent cycle times and reduced rework are priorities.

Secure clamping and accurate depth control for productive set‑ups

A Weldon shank with drive flat provides a robust connection to standard tool holders, reducing slippage during heavy cuts and supporting higher axial loads. The tool’s 16 mm diameter and 42 mm effective length give a compact, rigid package that reduces chatter and improves dimensional stability compared with longer end mills. The centre‑cutting capability permits controlled plunging, so interrupted cuts and slotting operations are possible without auxiliary pre‑drilling — a practical advantage that shortens process steps on the shop floor.

Geometry tuned for surface quality and chip evacuation

The four‑edge configuration combined with a precision‑ground flute profile promotes even chip formation and evacuation, leading to a superior surface finish on workpieces. A 45° chamfer at the cutting edge reduces burr formation at entry and helps guide the workpiece into the cut, while the honed fine flute profile contributes to robust edge support, especially in cast materials. Together these features reduce secondary finishing time and support predictable part tolerances in serial production.

Practical suitability and workshop integration

With an overall length of 92 mm and a 16 mm shank diameter, the tool integrates easily into standard toolholding systems. Material suitability data indicates very good performance on steel and cast iron, with conditional use on non‑ferrous alloys, making the cutter versatile for workshops that handle mixed batches. The right‑hand cutting orientation aligns with conventional milling spindle setups, allowing immediate use with common CAM strategies and minimising programming complexity when replacing existing cutters.

FAQ

Is this cutter suitable for plunge cutting and slotting?
The TECWERK HSS‑Co5 end mill has a centre‑cutting geometry, allowing controlled plunging and slotting operations without pre‑drilling in many applications.

Which materials is this cutter best suited to machine?
This cutter provides very good performance on steel and cast iron; non‑ferrous metals are conditionally suitable according to the tool’s geometry and uncoated state.

What does DIN 844 signify for this tool?
DIN 844 indicates standardised dimensions and tolerances for HSS end mills, ensuring consistent fit and predictable performance across similar cutters.

Does the Weldon shank improve clamping security?
Yes, the Weldon shank with drive flat is designed to reduce slippage under axial and radial load, improving stability in repetitive machining tasks.

What maximum material strength can be machined with this tool?
As supplied uncoated, the tool is intended for materials up to approximately 800 N/mm²; coating would extend applicability to higher tensile strengths if used.
