PEX - General Type Coated End Mill HRC45 End Mills

Dohre PEX series carbide end mill is manufactured using ultra-fine micro-grain carbide with grain size below 0.8 μm and 10% cobalt content, providing a balanced combination of hardness and toughness.

All milling tools are coated with an ALTIN nano composite coating, which offers excellent heat resistance up to 1100°C. The high aluminum content improves oxidation resistance and red hardness, allowing the cutter to maintain performance during long machining cycles.

With a positive rake angle of 6°, and 35° helix angle, Dohre PEX series end mill ensures smooth chip evacuation and reduced cutting forces. This makes the tools suitable for a wide variety of CNC machining applications.

Dohre PEX series includes Square End Mills, Corner Radius End Mills, and Ball Nose End Mills, each designed for different machining tasks while sharing the same carbide substrate, coating system, and manufacturing standards.

	PEX Square End Mill Designed for slotting, side milling, and finishing operations that require sharp edges and high efficiency. It is ideal for general CNC machining and flat surface finishing.
	PEX Corner Radius End Mill Featuring a reinforced corner radius, this tool improves edge strength and reduces chipping. It is especially suitable for stainless steel machining and mold components where durability and surface consistency are important.
	PEX Ball Nose End Mill Used mainly for 3D contouring, profiling, and curved surface finishing. The ball nose design ensures smooth transitions and high-quality surface finishes in mold and die applications.

Different industries and machining tasks require different end mill geometries. Dohre PEX series offers square end mills, corner radius end mills, and ball nose end mills, allowing users to select the most suitable tool based on industry application and machining purpose.

1. Advanced Tool Design Engineering

Our cutting tools are developed by our experienced engineering team with deep understanding of CNC machining applications. Tool geometry, rake angles, and edge preparation are optimized based on real machining feedback to ensure stable cutting performance and reliable tool life in daily production.

2. 100% Virgin Carbide Material

All PEX Series carbide end mills are produced using 100% virgin ultra-fine grain carbide, ensuring consistent material quality and mechanical properties. This provides a balanced combination of hardness and toughness, which is essential for stable machining and reduced risk of edge failure.

3. High Precision 5-Axis Grinding Machine

Production is manufactured on German Walter 5-axis CNC grinding machines, allowing precise control of cutting edge geometry, helix angle, and flute form. This guarantees sharp cutting edges, accurate dimensions, and smooth chip flow during machining.

4. Controlled Edge Preparation Process

Edge honing is completed using automated equipment with rubber diamond abrasive polishing. The edge preparation value is strictly controlled within ±0.003 mm, ensuring consistency across all tools while improving edge strength and surface finish.

5. Comprehensive Inspection System

Each end mill undergoes multi-stage inspection using Walter Helicheck Plus, combined with high-magnification optical measurement and appearance inspection. For ball nose and corner radius tools, radius accuracy is controlled within 3 μm, ensuring high dimensional reliability.

6. 100% Quality Inspection Before Shipment

Every end mill is 100% inspected before shipment. Dimensional accuracy, cutting edge condition, coating quality, and overall appearance are verified to ensure each tool meets our quality standards and delivers stable performance in actual machining.

7. Certified Quality Management Systems

Our manufacturing process is operated under internationally recognized management standards. The factory is certified to ISO 9001 (Quality Management), ISO 14001 (Environmental Management), and ISO 45001 (Occupational Health and Safety Management).

These certifications ensure stable production processes, consistent product quality, and long-term manufacturing reliability.

8. Authorized Distributors & Market Support

In addition to our main factory in Dongguan and Changzhou in China, we also have factory in Vietnam, providing flexible production capacity and stable lead times for international orders.

To better serve overseas markets, we work with authorized distributors in Iran and Turkey, offering local support, faster communication, and reliable regional supply.
