Product Description
Brief Overview
This 4mm rotary burr features a precisely engineered WRC profile with dense diagonal cross-cut spiral flutes, designed for finishing operations that demand superior surface quality. The compact 4mm head paired with a 50mm total length makes this tool ideal for detail work, deburring, and shaping in precision machining environments. If you require larger capacity options, consider our 6mm cross-cut rotary burr or alternative 4mm profile for expanded application flexibility.
Key Features
- 4mm head diameter with oval/ball-shaped cutting profile for smooth, controlled material removal
- Dense spiral cross-cut flutes produce a fine, consistent finished surface on workpieces
- 50mm total length (16mm cutting head, 50mm shank length) — compact proportions suited to precision work
- S6 shank — standard mounting for rotary tool chucks and flexible shaft systems
- All-metal construction — carbide or high-speed steel composition ensures durability and heat resistance
- Polished steel shank — smooth engagement and reduced friction during operation
Business Advantages for Resellers
High-Margin Addition to Your Inventory: Rotary burrs are frequently reordered consumables in tool production shops and precision machining facilities. Stock this compact 4mm profile alongside larger diameters to capture repeat orders from the same customer base.
Accessibility for Entry-Level Operations: The 4mm size opens doors to smaller job shops, dental labs, and electronics manufacturers who require precision burrs but lack the investment budget for larger tool sets. Lower unit cost means faster turnover and customer acquisition.
Complement to Larger Tool Assortments: Bundle this burr with 6mm, 8mm, and 10mm variants to create attractive multi-tool packages for resellers targeting workshops upgrading their finishing capabilities.

Why Distributors Choose This Profile
The WRC cross-cut design delivers a superior finish compared to standard single-flute burrs, reducing secondary finishing steps and accelerating job completion. The 4mm size fills a critical gap in precision shops that need control and finesse over raw cutting speed, making it a natural repeat purchase for customers already committed to quality workmanship.
Stock this alongside larger 6mm and 8mm rotary burrs to build a complete portfolio and maximize your shop's finishing capabilities.
