Quarter‑circle profile cutter DIN 6518B Type N, R3.5 mm, Ø13 mm (ALPEN‑MAYKESTAG)

Quarter‑circle profile cutter DIN 6518B Type N crafted from cobalt‑alloy high‑speed steel for milling concave quarter‑round profiles in structural and tempered steels with a Weldon shank for reliable clamping

• HSS‑Co material for high wear resistance
• Concave R3.5 mm profile for precise quarter rounds
• Weldon shank with 12 mm shaft for secure clamping
• Very good suitability for steel milling

Consistent profile geometry reduces finishing time

The concave profile with a radius of R3.5 mm and a nominal diameter of Ø13 mm delivers repeatable quarter‑round contours that reduce secondary finishing and accelerate assembly processes. With four flutes and a cutting length of 4 mm, the tool produces a fine, regular chip flow that helps maintain dimensional stability across multiple passes. For production environments where component fit and joint appearance matter, the controlled geometry translates into fewer rejects and shorter rework cycles.

Material and application: reliable performance on steels

Manufactured from HSS‑Co, this cutter is optimised for machining construction steels and other carbon or tempered steels, where toughness and edge retention are essential. The composition of the high‑speed cobalt alloy supports elevated temperatures at the cutting edge and extends tool life under interrupted cuts typical in profile milling. Suitability for stainless steel, cast materials and non‑ferrous metals is conditional; selection should be based on workpiece hardness and machining strategy to achieve best results.

Secure clamping and improved runout behaviour

The Weldon shank and 12 mm shaft dimension provide stable seating in toolholders and holders with set screws, reducing slippage during torque‑intensive operations. Stable clamping minimises runout, which in turn preserves surface finish and prolongs cutter life. The solid shank design is particularly advantageous in light‑to‑medium milling centres and in handheld milling set‑ups where reliable axial force transfer is required.

Practical guidance for setup and use in production

The cutter is right‑hand cutting, designed for conventional milling directions and requires appropriate feed and speed settings to match workpiece material and machine rigidity. The overall length of 60 mm offers a balance between accessibility and stiffness for profile work on edges and small radii. For repeatable results, begin with conservative feeds and increase incrementally while monitoring chip formation; tool life and surface quality typically improve when cutting parameters are adapted to the specific steel grade.

FAQ

What materials is this cutter best suited for?
The quarter‑circle profile cutter is made from HSS‑Co and is very well suited for steel machining; suitability for stainless steel (INOX), cast materials and non‑ferrous metals is conditional and depends on workpiece hardness.

What is the exact profile radius of the cutter?
The tool features a 3.5 mm concave radius, giving a precise quarter‑round profile ideal for decorative and functional edge milling.

How is the tool held in the spindle?
This cutter uses a Weldon shank with a 12 mm shaft, designed for secure clamping with set‑screw toolholders to reduce slippage and runout.

How many cutting edges does the cutter have and what is the cutting length?
The cutter is supplied with four flutes and a cutting length of 4 mm, which supports smooth chip evacuation and consistent surface finish.

Can the cutter be used in CNC machining centers?
Yes; the quarter‑round cutter suits CNC and manual milling where the machine provides sufficient rigidity; start with conservative feeds and adjust based on material and machine response.
