Quarter‑round profile cutter DIN 6518B Typ N, R8, D24, HSS‑Co, Weldon – ALPEN‑MAYKESTAG

Quarter‑round profile cutter DIN 6518B Typ N for concave profiling and finishing on steels, featuring a R8 form and a rigid Weldon shank for reliable tool holding

• HSS‑Co for enhanced wear resistance
• Concave R8 quarter‑round profile for finishing cuts
• Weldon shank Ø16 mm with drive flat for rigidity
• Right‑hand cutting with four flutes for smooth chip flow

Consistent performance for steel machining

The HSS‑Co construction combines toughness with heat resistance, enabling prolonged tool life when profiling carbon and alloy steels. The cobalt alloy resists thermal softening during continuous operation, which translates into fewer tool changes and higher machine uptime. The R8 quarter‑round geometry produces precise concave contours while maintaining surface quality, making this cutter suited to serial profiling and fine finishing tasks in job shops and contract machining.

Stable clamping and vibration reduction on the spindle

A Weldon shank with a 16 mm diameter and drive flat provides secure axial and torsional clamping in the tool holder, reducing run‑out and vibration during heavy engagement. With an overall length of 71 mm and a nominal diameter of 24 mm, the tool keeps overhang moderate for typical pocketing and profiling operations, while the cutting length of 4 mm focuses material removal on the intended profile without unnecessary deflection. These dimensions support repeatable setups and tighter tolerances on machined contours.

Optimised geometry for clean chips and fine surfaces

The cutter’s concave R8 form and four flutes ensure balanced cutting forces and improved chip control, which helps achieve a consistent surface finish on radiused grooves and fillets. Classified to DIN 6518 B Typ N, the profile is engineered for shape accuracy and edge stability; the right‑hand cutting direction supports conventional and climb milling strategies depending on fixture and machine dynamics. For users unfamiliar with the term: a quarter‑round profile produces a 90° arc section, ideal for radiused edges and decorative or functional grooves.

Practical applications and material compatibility

Designed primarily for construction and tempered steels, the tool is very well suited to ferrous machining tasks while remaining conditionally suitable for stainless steels, non‑ferrous metals and cast materials in light engagement or finishing passes. The combination of robust cutting grade and compact profile makes it suitable for toolmaking, mould and die finishing, and general workshop profiling where consistent radii and repeatable surface quality are required. Recommendations for cutting data and feeds can be provided to aid integration into production workflows.

FAQ

What materials is this cutter best suited to?
The quarter‑round profile cutter is very well suited to steels, giving the best balance of life and surface finish on carbon and alloy steels; stainless, non‑ferrous and cast materials are conditionally suitable for finishing passes.

How does the Weldon shank benefit machining?
A Weldon shank with a drive flat ensures secure clamping and reduced torsional slip in the holder, improving concentricity and helping the cutter maintain repeatable profiles under load.

What surface finish can be expected from the R8 profile?
The R8 concave profile produces a smooth, radiused groove suitable for visible finishes or functional fillets when used with appropriate feeds and spindle speeds.

How many cutting edges does the tool have and why does it matter?
The cutter has four flutes; this increases chip distribution and smooths cutting forces, which helps achieve a consistent finish and extends tool life in profiling operations.
