TECWERK End Mill DIN 844 Type HR – HSS-Co5, Ø 6 mm, Cutting Length 19 mm

The TECWERK end mill DIN 844 Type HR, Ø 6 mm, is a short four-flute cutter designed for precision milling in steel and cast iron applications, offering centre-cut capability and a Weldon shank for secure clamping.

• HSS-Co5 high-alloy cutting steel
• Short four-flute design for rigidity
• Weldon shank with drive flat
• Centre-cut and 45° entry chamfer

Outstanding material performance for robust steels

The HSS‑Co5 composition provides increased hot hardness and wear resistance compared with standard high-speed steels, which translates into longer tool life under elevated cutting temperatures. This cutter is specified to machine steels up to approx. 800 N/mm² with an uncoated tool and up to approx. 1200 N/mm² when a suitable coating is applied, making it a dependable choice for demanding shop-floor tasks. The standardised construction to DIN 844 ensures consistent geometry across batches, supporting process repeatability and easier tool qualification.

Secure clamping and clean chip control for consistent finishes

A Weldon shank with a drive flat provides a positive mechanical grip in the holder, reducing the risk of slippage during interrupted cuts and heavy engagements. The four‑flute short design increases radial support and minimises deflection, producing a finer surface finish on shoulders and profiles. The tool’s centre‑cut geometry allows limited plunge milling, while the 45° chamfer at the cutter tip eases entry and reduces burr formation. Together these features improve machining stability and reduce the need for secondary finishing.

Practical application guidance for workshop and CNC use

Designed as a compact, high‑rigidity cutter, the short version is particularly suitable for operations where chatter must be avoided and where space limits tool overhang. The 6 mm nominal diameter and 19 mm cutting length strike a balance between reach and stiffness, optimising axial engagement for slotting and side milling in structural parts. The relief‑ground fine profile delivers controlled chip formation, and the cylindrical shank with drive flat simplifies holder selection and repeatable set-up on both manual milling machines and CNC centres.

FAQ

What materials is this cutter best suited for?
The TECWERK end mill is very well suited to steel and cast iron; it is conditionally suitable for non‑ferrous materials, with highest performance on structural steels up to the stated strength classes.

Can the tool perform plunge milling?
Yes, the centre‑cut geometry enables limited plunge milling; however, the tool is optimised for short, rigid engagements and side milling for the best surface results.

How does the Weldon shank benefit the machining process?
A Weldon shank with drive flat offers secure mechanical clamping in standard holders, which reduces slippage and helps maintain repeatable tool position during interrupted cutting.

Is a coating required for harder materials?
For workpieces approaching the upper strength range, a suitable coating extends tool life and raises the effective machining capacity to about 1200 N/mm² compared with the uncoated tool performance.

What standards and size options does the cutter follow?
The cutter complies with DIN 844 dimensions and geometry; this particular item offers a 6 mm diameter and a 19 mm cutting length, making it suitable for compact machining tasks.
