Working principle
The D6R3 ball cutter disperses cutting forces and reduces local stress concentration by contacting the workpiece surface with its spherical cutting head. The spiral design of the blade helps to achieve smooth chip removal and reduce cutting heat accumulation. Combined with a high-speed spindle and stable feed rate, the tool can achieve extremely smooth machining surfaces.
High precision: Ensure consistency and precision of complex surfaces.
Customizable: Adjust the length, number of blades, and coating according to customer needs.
FAQ – Aerospace Carbide Drills & End Mills
Q1: Are these tools suitable for titanium alloys and Inconel?
A1: Yes. Our carbide drills and end mills are designed for aerospace-grade materials such as titanium alloys, nickel-based alloys (Inconel), stainless steels, and composites. Optimized cutting geometry and advanced coatings ensure excellent performance.
Q2: What coating options are available?
A2: We provide TiAlN, AlTiN, nano-composite, and DLC coatings. Each coating enhances wear resistance, reduces friction, and withstands high cutting temperatures in aerospace machining.
Q3: Do you offer internal coolant tools?
A3: Yes. Internal coolant drills and end mills are available, designed for high-pressure coolant supply to improve chip evacuation and extend tool life during deep-hole and high-heat cutting.
Q4: How do your tools compare with international brands (Sandvik, Kennametal, Seco, OSG)?
A4: Our tools deliver comparable cutting life and stability, often with better cost-performance ratio. In many aerospace applications, tool life can be extended by 15–30% compared to standard tools.
Q5: Can I request customized tool dimensions or geometries?
A5: Absolutely. We provide tailored solutions for deep holes, thin-walled parts, and complex aerospace structures, ensuring optimal machining efficiency and precision.
Q6: What is the expected tool life when cutting titanium alloys?
A6: Tool life depends on cutting conditions, but with optimized coatings and internal cooling, our drills and end mills can achieve significantly longer service time compared to conventional tools.
Q7: What certifications do you provide?
A7: Tools can be supplied with material certificates, quality inspection reports, and conformity documents that meet aerospace industry standards.
Q8: How fast can you deliver standard and customized tools?
A8: Standard tools are available from stock. Customized tools usually require 2–4 weeks, depending on specifications.
Q9: Do you support trial orders before mass purchase?
A9: Yes. Trial orders are welcome so customers can evaluate tool performance and stability in their specific aerospace machining environment.
Q10: What are the main advantages of your tools?
Ultra-fine carbide substrate for maximum toughness and hardness
Advanced coatings for high heat resistance
Internal coolant design for aerospace applications
Precision manufacturing for consistent accuracy
Cost-effective compared to imported brands
