TECWERK end mill DIN 844 HR, 16 mm — HSS‑Co PM, ALCRONA, 4‑flute, Weldon shank

The TECWERK end mill DIN 844 HR, 16 mm is a short, high‑stiffness HSS‑Co PM four‑flute cutter with an ALCRONA coating, designed for precision milling of high‑strength steels and inox components

• Short HSS‑Co PM end mill with Weldon shank
• ALCRONA coating for enhanced wear resistance
• 4‑flute geometry with centre cut
• Suitable for steels up to 1400 N/mm²

Reliable cutting performance for high‑strength steels

The combination of HSS‑Co PM construction and an ALCRONA coating delivers a balance of toughness and wear resistance that is well suited to elevated cutting stresses. The powder‑metallurgy HSS core provides a homogeneous microstructure for consistent edge behaviour, while the coating reduces adhesive wear and prolongs life under intermittent contact. This configuration enables stable machining of materials up to approximately 1400 N/mm², translating into fewer tool changes and increased process uptime for production and repair shops.

Stiffness and chip control optimised by geometry and relief

A short design with a conical flute root improves bending resistance compared with longer variants, reducing chatter and improving surface finish in shoulder milling and finishing passes. The 4‑flute geometry supports higher feed rates and better surface integrity by increasing cutting edge overlap, while the centre‑cut capability permits limited plunging without pre‑drilling. The cutter’s 45° chamfer provides a protected cutting edge for interrupted cuts, and the specified relief dimensions contribute to reliable chip evacuation in interrupted and continuous cuts.

Practical mounting, dimensions and intended applications

Mounting is via a Weldon shank / cylindrical shank with drive flat, ensuring secure clamping in Weldon holders or suitable end mill arbors; the shank diameter is 16 mm matching the tool diameter. Key dimensions—overall length 92 mm, effective length 42 mm, and cutting length 4 mm—define the working envelope and make the tool particularly suitable for short‑reach finishing, pocketing and face milling on compact components. Right‑hand cutting direction and DIN 844 Type HR classification indicate an industry standard geometry for reliable integration with existing tool sets.

Material suitability and user guidance

Material suitability is specified to help select the tool for the correct task: very good performance on steels and stainless steels, good performance on cast materials, and conditional suitability for non‑ferrous metals and high‑strength special alloys. Conditional suitability indicates that process parameters (feeds, speeds and cooling) must be adapted and test cuts carried out before production runs. Operators are advised to favour low‑to‑moderate cutting speeds and to verify coolant strategies when machining stainless or high‑alloy steels to avoid work‑hardening and excessive heat buildup.

FAQ

Which materials are best machined with this cutter?
The TECWERK end mill DIN 844 HR (SKU 2000866063NW) is specified as very good for steels and stainless steels, very good for cast materials and conditionally suitable for non‑ferrous metals and special alloys; process tests are recommended for the conditional materials.

Can this cutter be used for plunge milling?
Yes — the tool features a centre‑cut geometry that allows limited plunging and spot drilling without pre‑drilling, aided by the four‑flute design and short cutting length for controlled entry.

What are the mounting and dimensional details?
Mounting is via a Weldon / cylindrical shank with drive flat; diameter and shank are 16 mm, overall length 92 mm, effective length 42 mm and cutting length 4 mm.

How does the ALCRONA coating help in machining?
The ALCRONA coating reduces adhesive wear and improves thermal stability at the cutting edge when combined with the HSS‑Co PM substrate, extending tool life under demanding intermittent cutting conditions.

What does DIN 844 Type HR mean and when is the short version used?
DIN 844 Type HR denotes a short‑length end mill profile optimised for stiffness and finish. The short version is preferred for shoulder milling, finishing passes and applications where reduced stick‑out improves stability and surface quality.
