TECWERK HSS‑Co5 End Mill D 10 mm – DIN 844 Type HR, 4‑flute (Weldon TW)

The TECWERK HSS‑Co5 End Mill D 10 mm is a DIN 844 Type HR shank cutter engineered for precision milling and finishing of steel and cast iron components.

HSS‑Co5 alloy for high wear resistance
Short 4‑flute design for stable finishing
Weldon TW shank with drive flat for secure clamping
Suitable for steel and cast iron up to ≈800 N/mm²

Better throughput through material‑matched tooling

The tool’s HSS‑Co5 composition offers higher hot hardness compared with conventional high‑speed steels, which translates into improved edge life when machining tougher grades. As a result, the cutter maintains cutting geometry longer under thermal load, reducing the frequency of tool changes and supporting steady production cycles. The specification that uncoated tools are suitable up to approximately 800 N/mm², with higher limits achievable when using coated variants, gives a clear baseline for tool selection and process planning. This makes the cutter a rational choice where cost‑effective endurance is required.

Secure clamping and reduced vibration for consistent surface quality

A short 4‑flute profile combined with the Weldon TW cylindrical shank with drive flat ensures positive torque transmission and low runout in standard toolholders. The D 10 mm geometry with an effective cutting length 30 mm and overall length 72 mm provides a compact, rigid package that minimises deflection during light to medium finishing passes. The presence of a centre cut allows light plunging and positional entry, while the 45° protective chamfer contributes to edge robustness. Together these design elements help achieve repeatable surface finish and dimensional stability on production parts.

Practical integration and material suitability

Manufactured to DIN 844 Type HR dimensions, the cutter is optimised for practical use in workshop and industrial environments. It is right‑hand cutting and presents a fine relieved cord profile that supports clean chip formation. Material suitability is clearly defined: steel (very well suited), cast iron (very well suited) and non‑ferrous metals (conditionally suitable). The tool features a relief zone of 9.5 mm where specified, improving clearance and reducing rubbing in deeper slots. For best results, pair the cutter with appropriate feeds and speeds for HSS‑Co tooling and ensure secure holder clamping to exploit the cutter’s rigidity.
