3mm Rotary Milling Burr, RBF Type, S3 Profile

Brief Overview

This 3mm rotary milling burr delivers precision finishing and material removal for tool production, machining, and deburring applications. The RBF profile combines a tapered cutting head with helical cross-cut flutes, designed to produce smooth, accurate finishes on workpieces across multiple construction forms and materials. For shops requiring a complete range of rotary cutting tools, consider pairing this with larger 6mm and 8mm RBF burrs to cover diverse job specifications.

Key Features

• Compact 3mm Shank: Fits standard rotary tool chucks and flexible shaft assemblies
• 38mm Total Length: Suitable for precision work in confined spaces and detailed machining
• Cross-Cut Helical Flutes: Multi-directional cutting teeth ensure smooth material removal and reduce chatter
• Tapered Head Profile: Concentrates cutting force at the tip for controlled finishing passes
• Bright Steel Construction: Hard metal composition for durability across extended production runs
• Rounded Tip Design: Prevents sharp edge damage to workpiece surfaces and extends tool life

Business Advantages for Resellers

• High-Volume Production Tool: Essential consumable for tool shops, job shops, and precision manufacturers
• Repeatable Orders: Shops typically stock multiple units; single-unit packaging allows flexible inventory management
• Competitive Margin: Low material cost with strong markup potential on bulk orders
• Turnover Driver: Small-size precision tools generate consistent repeat purchases from active shops
• Quality Assurance: Consistent RBF geometry ensures customer satisfaction and fewer returns
