Quarter‑circle profile cutter DIN 6518B Type N R4 mm D14 mm HSS‑Co Weldon by ALPEN‑MAYKESTAG — concave profiling tool with 12 mm shank

A Quarter‑circle profile cutter DIN 6518B Type N R4 mm D14 mm HSS‑Co designed for precision concave milling in construction, alloy and tempered steels with a secure Weldon drive.

• HSS‑Co for high wear resistance
• Concave quarter‑round R4 profile
• 12 mm Weldon shank with drive flat
• Optimised for machining construction steels

Precision profile for repeatable concave contours

The cutter is manufactured from HSS‑Co, a cobalt‑alloyed high‑speed steel that improves hot hardness and wear resistance during demanding milling. With a 14 mm diameter and a 4 mm profile radius, the tool produces uniform quarter‑round contours, making it suitable for decorative and functional profiling where a consistent concave geometry is required. The combination of material and geometry reduces heat‑related wear, extending tool life and supporting steady production runs.

Secure clamping and stable cutting performance

Featuring a 12 mm Weldon shank with a drive flat, the cutter offers reliable torque transmission and reduced slippage in collets and chucks. The tool’s right‑hand cutting direction and four flutes deliver balanced chip evacuation and smooth surface finish when profiling steels. These mechanical properties translate into fewer reworks and predictable cycle times, which supports improved throughput in workshop and small‑batch industrial environments.

Clear material suitability to match application needs

Specified for machining construction, alloy and tempered steels, the cutter is rated very suitable for steel workpieces; suitability for non‑ferrous metals, stainless steel and cast iron is restricted, so feed and speed should be adjusted accordingly. Understanding these limitations helps planners select the cutter where it performs best, avoiding suboptimal tool life on inappropriate materials and ensuring consistent part quality when used within its intended range.

Practical dimensions and handling for workshop use

With an overall length of 60 mm and an effective cutting length of 4 mm, the tool is compact and straightforward to integrate into vertical and horizontal milling setups. The modest projection reduces vibration and improves surface finish on concave profiles. The concave form of the cutter simplifies finishing steps and reduces the need for secondary operations, supporting efficient workflows in toolrooms and production cells.

FAQ

What materials is this quarter‑round cutter best suited for?
The ALPEN‑MAYKESTAG quarter‑round profile cutter is very suitable for steel, while use on non‑ferrous metals, stainless steel and cast iron is possible but limited; adjust feeds and speeds accordingly.

How is the tool clamped and secured in the spindle?
The tool uses a 12 mm Weldon shank with a drive flat, providing secure clamping and reliable torque transmission in standard collets and holders for stable milling.

What does DIN 6518B Type N indicate for this cutter?
DIN 6518B Type N specifies the quarter‑round profile geometry and tolerances; the designation ensures the cutter’s concave profile meets industry standards for repeatable contour milling.

How many cutting edges does the cutter have and what is the benefit?
The cutter has four flutes, which balance cutting forces and chip evacuation to deliver smoother surface finishes on concave profiles and improved tool life.

Can this cutter be used for finishing hardened steels?
The cutter is manufactured from HSS‑Co, optimised for alloy and tempered steels; it is not specified for very hard steels near through‑hardness limits, so application in hardened materials should be verified.
