28mm Quarter-Round Profile Cutter R10, HSS-Co 4-Flute Right-Hand, Weldon 25mm Shank - ALPEN-MAYKESTAG GmbH

Take advantage of the combination of HSS‑Co construction, Weldon shank with drive flat and the concave R10 profile for consistent profile milling of construction and tempered steels. Order the quarter‑circle profile cutter directly via Metav Werkzeuge or ask our consultants if needed.

Quarter‑circle profile cutter DIN 6518B Type N, R10 mm, D28 mm — HSS‑Co, Weldon shank

Quarter‑circle profile cutter for precision concave profiling in structural, engineering and tempered steels with right‑hand cutting and secure Weldon clamping

• HSS‑Co for increased wear resistance
• Weldon shank with drive flat for secure clamping
• Quarter‑circle R10 concave profile cutter
• Very good suitability for steel machining

Precision profile results for production parts

The combination of a concave R10 geometry and a 28 mm diameter provides consistent contour milling for components where profile accuracy matters. The cobalt‑alloy HSS‑Co substrate keeps the cutting edges sharper for longer under intermittent loads, which helps to reduce rework and maintain tolerances in serial production. Where profile form and surface finish are critical, this tool delivers repeatable results when paired with stable fixturing and appropriate feed rates.

Stable clamping and reliable tool engagement

A 25 mm Weldon shank with drive flat offers secure retention in standard three‑jaw and hydraulic chucks, reducing the risk of slippage during high torque operations. With a right‑hand cutting orientation and four flutes, the cutter balances cutting force and surface finish, enabling controlled engagement in both slotting and profiling passes. This stability supports predictable cycle times and decreases vibration‑related tool wear, contributing to improved machine uptime.

Material suitability and machining efficiency

Designed primarily for construction, case‑hardened and tempered steels, the cutter shows very good suitability for steel and conditional suitability for stainless, non‑ferrous metals and cast materials. The four‑cutting‑edge design promotes efficient material removal while maintaining surface quality, which can shorten downstream finishing operations. For applications requiring higher cutting speeds, ensure machine power and workholding match the tool’s capacity to exploit the HSS‑Co advantages.

Practical advantages and workshop integration

With an 85 mm overall length and a 4 mm cutting length, the tool integrates well into compact tool magazines and multi‑operation setups. The concise cutting zone aids chip control and helps prevent excessive tool overhang. For shops consolidating suppliers, this tool’s adherence to DIN 6518B Type N provides compatibility with established tool holders and replacement schedules, smoothing procurement and inventory management across production lines.

FAQ

What materials is this cutter best suited to machine?
The ALPEN‑MAYKESTAG quarter‑circle profile cutter (SKU 4117802018NW) is designed for excellent performance on construction and tempered steels; it is conditionally suitable for stainless steel, non‑ferrous metals and cast materials.

How is the tool clamped in the spindle?
A 25 mm Weldon shank with drive flat provides secure clamping in standard chucks and reduces the risk of slippage under torque when the cutter is used according to recommended feeds and speeds.

What is the profile geometry and where is it used?
The tool features a concave quarter‑circle profile with R10, ideal for producing rounded grooves, fillets and decorative or functional concave contours in structural components.

Is a coating applied to the cutter for additional wear resistance?
No specific coating is indicated for this cutter; wear resistance is provided by the HSS‑Co material itself, which suits intermittent heavy‑duty cutting in steels.

How many flutes does the cutter have and what does this mean for cutting?
The cutter has four flutes, which balance chip evacuation and surface finish; this configuration supports efficient material removal while maintaining a good finished surface quality.
