Description

Ball-End Rotary Burr, 12mm Head Diameter, 56mm Overall Length, S6 Shank

Brief Overview

This 12mm ball-end rotary burr is engineered for precision internal profiling, corner deburring, and cavity finishing in tool production and precision machining operations. The spherical cutting head, coupled with closely-spaced helical flutes, delivers smooth surface finishes on complex geometries and internal corners. The 6mm S6 shank accommodates standard rotary tool holders and flexible shaft systems. Pair this with smaller ball-end burrs for detail work or larger format burrs for production runs to build a complete internal profiling toolkit for your customers.

Key Features

  • Spherical cutting head: Optimized for internal corner profiling and rounded edge deburring
  • Helical flute geometry: Ensures smooth material removal and superior surface finish without chatter
  • Compact 56mm overall length: Ideal for accessing confined cavities and deep internal profiles
  • 6mm S6 shank: Direct compatibility with rotary tool chucks and flexible shaft adapters
  • Precision-ground construction: Maintains consistent geometry across production runs

Business Advantages for Resellers

  • High-volume production appeal: Tool manufacturers and precision job shops rely on these burrs for cavity finishing and corner detail work—steady repeat orders
  • Complementary sizing: Stock alongside smaller and larger ball-end formats to offer customers complete internal profiling solutions
  • Margin-friendly pricing: Compact size and specialized profile support healthy markups while remaining cost-competitive against premium imported alternatives
  • Diverse customer base: Automotive tooling, jewelry production, plastic/composite machining, and general precision work all require internal profiling capability

Application Context

This ball-end rotary burr excels at:

  • Rounding and finishing internal sharp corners
  • Deburring slots, cavities, and confined geometric features
  • Profiling complex internal shapes without edge chipping
  • Creating smooth transitions in precision molds and dies

The compact 56mm length provides access to deep internal features while the 12mm head diameter balances cutting capacity with maneuverability in tight workspaces.
