Rotary Burr 8×65 mm WRC S6, Cross-Cut Ball Head for Precision Milling

Brief Overview

This 8×65 mm rotary milling burr is engineered for tool production facilities and precision machining operations requiring consistent, high-quality surface finishes. The WRC series designation indicates a cross-cut ball-head design—ideal for both roughing and finishing work on various construction geometries. The robust 6 mm shank accepts standard rotary tool collets, making it compatible with most pneumatic and electric rotary platforms. If your operation regularly works with smaller geometries, consider complementary smaller-diameter cross-cut burrs or the comparable 8×63 mm finishing alternative for expanded capability across your burr inventory.

Key Features

• Cross-cut flute geometry: Multi-directional diagonal fluting creates aggressive cutting action with excellent chip evacuation
• Oval/ball-shaped cutting head: Optimal for contouring, finishing, and detailed material removal on curved and complex surfaces
• 8 mm working diameter: Balanced size for precision work—larger than micro-burrs, smaller than coarse roughing tools
• 65 mm total length: Extended reach for recessed or deep-cavity machining without tool interference
• Polished metal finish: Protective shank engraving ensures traceability; uniform metallic surface resists corrosion
• 6 mm shank diameter: Standard collet compatibility across industrial rotary tool ecosystems
• Precision manufactured: Flute uniformity guarantees repeatable cutting performance and predictable surface quality

Business Advantages

• High-volume tool production: Essential consumable for job shops, tool & die facilities, and precision manufacturing environments
• Versatile application range: Cross-cut design handles both ferrous and non-ferrous materials, from aluminum to steel and composites
• Smooth surface guarantee: Image-documented flute pattern delivers the glass-like finishes that command premium pricing in finishing work
• Bulk stocking opportunity: Standard size in the mid-range burr portfolio—drives repeat orders and customer loyalty
• Cost-effective per-unit: Competitive pricing on consumable rotary tooling increases distributor margin and customer lifetime value

Applications

• Precision contouring: Ideal for shaping, profiling, and detailed edge work on prototype and production components
• Tool & die finishing: Delivers the smooth surfaces required for injection molds, dies, and gauges
• Material removal on complex geometries: Cross-cut design excels on curved surfaces, cavities, and internal passages
• Surface preparation: Removes burrs, parting lines, and machining artifacts with minimal vibration
• Production consistency: Uniform flute geometry ensures batch-to-batch repeatability

Why This Burr in Your Inventory

The 8×65 mm WRC sits in the sweet spot between delicate micro-work and heavy stock removal. Its cross-cut fluting is the workhorse pattern for shops that demand both speed and finish quality. The extended 65 mm length opens up deeper cavity work without tool collision—a genuine advantage over shorter alternatives. Stock it as a core line item; your high-volume customers will order it regularly.
