DIN 844 Type HR End Mill D=18 mm — HSS‑Co5, TiCN‑coated, 4‑flute, Weldon shank (TECWERK)

The DIN 844 Type HR End Mill D=18 mm is a short, robust 4‑flute cutter designed for peripheral and slot milling of steels and cast iron in general industrial production.

• TiCN coating for extended tool life
• HSS‑Co5 substrate for high toughness
• 4‑flute geometry for superior surface finish
• Weldon shank with drive flat for secure clamping

High‑speed stability and material capability for efficient production

Built to the DIN 844 short‑type specification, this cutter combines a HSS‑Co5 substrate with a TiCN coating to balance toughness and surface hardness. The cobalt‑alloyed high‑speed steel increases resistance to thermal softening, while the titanium carbonitride layer reduces wear and helps limit built‑up edge. The result is a tool that maintains cutting performance over extended runs and supports efficient chip evacuation with its four‑flute geometry. Designed for industrial use, the cutter handles general steels very well and is particularly suited to cast iron workpieces, delivering reliable performance in repetitive production environments.

Practical design that improves setup and machining consistency

The short Type HR configuration and the Weldon shank with drive flat ensure a compact, rigid toolholder interface and reduced overhang, which lowers vibration and improves dimensional accuracy. A 45° protection chamfer and a centre‑cutting geometry allow plunge and peripheral milling without compromising edge strength. The tool features a fine, relieved cord profile behind the cutting edge for controlled flank contact and smoother cutting action. Combined, these design elements support stable machining, minimising rework and shortening cycle times in machining centres and rigid milling setups.

Application range, machining notes and recommended use

This cutter is right‑hand cutting and offers an 18 mm diameter with a 42 mm effective cutting length and a 16 mm shank for standard toolholders. It is classified as very well suited for steel and cast iron; non‑ferrous metals, special alloys and stainless steels are workable under specific conditions. For harder or alloyed materials, the TiCN coating increases the tool’s capability up to higher strength levels compared with an uncoated equivalent. For best results, pair the tool with rigid fixturing, appropriate coolant or lubrication per material recommendations, and a verified feed‑rate strategy to preserve edge life and surface quality.

FAQ

What materials is this end mill best suited for?
The TECWERK DIN 844 Type HR end mill is very well suited for steel and cast iron; non‑ferrous metals, special alloys and stainless steel can be machined under appropriate conditions.

Can the tool be used for plunge milling?
Yes. The centre‑cutting geometry allows plunge operations as well as peripheral milling when using the DIN 844 Type HR end mill.

What are the mounting requirements for secure clamping?
Use a suitable toolholder that accepts a 16 mm shank with a Weldon flat; the Weldon shank ensures positive drive and reduced slippage during heavy cuts.
