Square Shoulder End Mill

As a China manufacturer and supplier, wangdefu's 90° right angle Square Shoulder End Mill is ideal for engine blocks, machine beds, mold cavities and composite parts to ensure stability, precision and multi-material adaptability. High-precision, high-efficiency milling solutions for automotive, aerospace, tooling and general machinery applications.

What are the advantages of our knives?

Precision 90° Geometry + Reinforced Structure

Strict 90° main angle, precision tool body and insert positioning ensure shoulder perpendicularity ≤30μm and flatness ≤0.008mm.

Forged high-strength alloy steel body, heat-treated for rigidity. Dovetail or wedge-style insert locking ensures stable clamping and prevents deflection under deep cuts and interrupted milling.

Multi-Flute & Optimized Geometry

Tooth pitch options: L (coarse), M (medium), H (fine). Fine pitch increases feed efficiency; coarse pitch improves chip evacuation.

30°–45° helix angle with dual positive rake reduces cutting resistance by 30%, unequal tooth spacing suppresses vibration.

Square double-sided inserts provide 8 cutting edges; finishing edges achieve Ra ≤1.6μm, some precision variants reach Ra ≤0.8μm.

All-Material Compatibility + Enhanced Coatings

Inserts available in carbide, ceramic, CBN. Carbide suitable for steel, cast iron, aluminum; ceramic and CBN specialized for hardened steel and cold cast iron.

Coatings: TiAlN, TiCN, or CVD MT-TiCN+Al₂O₃, providing high-temperature resistance, anti-adhesion, and tool life >40% longer.

Multi-Function Integration + Flexible Adaptation

Combines face milling, edge milling, slotting, and plunge milling in one tool, reducing tool changes and setups, improving efficiency 68–140%.

Wide, deep helical flutes ensure smooth chip evacuation. Supports internal/external cooling.

Compatible with BT, HSK, Capto spindles, CNC mills, machining centers, and automated production lines. Indexable design lowers insert replacement costs.

Core Product Specifications

Where can we use our Milling Tools?

Automotive Manufacturing: Engine block steps and transmission housing mounting surfaces. Using a Quality Square Shoulder End Mill from Wangdefu, single-pass 90° shoulder formation can achieve perpendicularity ≤0.015mm, reduce machining time by 50%, and maintain scrap rate <0.5%. Trusted by manufacturers and suppliers in China for high-efficiency production.

Mold Manufacturing: 45 steel mold sidewalls and internal mold inserts rough/finish milling. Dry cutting tool life up to 3 hours, 3× longer than conventional tools, with no secondary polishing required. Many Chinese mold factories rely on Wangdefu tools for consistent precision and reliability.

Aerospace: Edge milling of composite components and step surfaces of metal structural parts. Multi-flute design ensures high material removal and stability under long overhangs, burr-free and delamination-free. Suitable for factories and suppliers needing high-performance machining solutions.

General Machinery: Step surfaces and right-angle grooves in pump bodies, valve bodies, and gearboxes. Integrates multiple operations, reducing production cost >30%, widely adopted by machine manufacturers and suppliers in China.

Recommended Cutting Parameters

Tip: For thin-walled or deep cavity parts, reduce feed and depth. Adjust parameters according to machine rigidity and workpiece structure. Contact Wangdefu technical team for custom solutions for difficult materials.
