End mill DIN 844 Type NR Ø16 mm, HSS‑Co5, Weldon shank — TECWERK

The End mill DIN 844 Type NR Ø16 mm is a short, multi‑flute cutter designed for reliable milling of steels and castings, featuring a Weldon shank for positive drive and a centre-cut for limited plunging.

• HSS‑Co5 for enhanced heat resistance
• Centre‑cut for controlled plunge milling
• Weldon shank with drive flat for secure clamping
• Very good suitability for steel and castings

High‑performance design for stable short‑run milling

The cutter’s combination of HSS‑Co5 material and a short design delivers notable rigidity and thermal resistance during intermittent cuts. The 4‑flute configuration balances surface finish and chip evacuation on interrupted surfaces, while the 42 mm effective length limits overhang to reduce vibration. Conformance to DIN 844 ensures consistent geometry across batches, which benefits machining repeatability and tool change standardisation on production lines. These design choices translate into fewer rejects and steadier cycle times where short to medium runs are required.

Material capability and recommended applications

Engineered for components up to approximately 800 N/mm² with an uncoated cutter (and up to 1000 N/mm² with suitable coating), this tool is very suitable for steel and castings and conditionally suitable for non‑ferrous metals. The centre‑cut geometry permits plunge or helical entry into the workpiece, enabling pocketing and repair tasks without pre‑drilling. In practice, the cutter is appropriate for roughing and light finishing of medium‑strength structural steels and cast parts where tool robustness and dependable chip formation are priorities.

Secure clamping and machining economy

The Weldon shank with drive flat provides secure torque transmission and simplifies mounting in Weldon holders, reducing slippage under heavy engagement. The Ø16 mm shank and body dimensions suit standard toolholders, keeping runout low and surface quality consistent. The 45° protective chamfer and relief‑ground flute profile contribute to controlled cutting edges and lower burr formation. Together these features reduce downtime from retightening or regripping and support predictable tool life, supporting cost‑effective production.

Practical handling and what the specifications mean for the workshop

Operators will appreciate that the cutter’s relief dimensions and helical profile aid chip evacuation, while the right‑hand cutting orientation matches conventional milling setups. The 15 mm relief (freischliff) helps maintain cutting geometry near the shank and improves stability when working close to shoulders. For optimised results, use toolholders rated for short overhangs and monitor cutting parameters to match material hardness; the cobalt content in HSS‑Co5 enhances wear resistance compared with standard high‑speed steels, giving a reliable balance between toughness and hot‑hardness for everyday shop use.

FAQ

Is this cutter suitable for plunge milling?
The cutter’s centre‑cut geometry allows controlled plunge and helical entries; the short, multi‑flute design supports pocketing and limited plunging operations with the TECWERK end mill (SKU 2000866430NW).

Which materials should be prioritised with this tool?
This cutter is very suitable for steel and castings and conditionally suitable for non‑ferrous metals; it is intended for components up to about 800 N/mm² with an uncoated tool, as specified for the TECWERK Type NR cutter.

What clamping system is recommended?
Use a Weldon holder or appropriate collet adaptor for the Weldon shank to ensure positive drive and minimise slippage; maintaining short overhang is advised for best stability.

How does the HSS‑Co5 alloy influence tool life?
The cobalt‑alloyed HSS‑Co5 provides improved hot‑hardness and wear resistance compared with standard HSS, which helps sustain cutting edge hardness under higher temperatures and extends practical tool life in intermittent cutting.

Can this cutter be used for finishing passes?
The 4‑flute geometry balances removal rate and surface quality; after optimising feeds and speeds it can perform light finishing passes, although final surface specification will depend on machine rigidity and fixture stability.
