The RSD Technologies Bur – Conical Radius End (1/2" x 1-3/16" x 3-1/4", SL-4-D) is engineered for machinists who demand aggressive cutting performance without sacrificing control or finish quality. Designed with a precision-ground conical radius profile, this bur is ideal for blending radii, contouring surfaces, and removing material in tight or curved areas where standard shapes fall short. Built to handle tough applications across steel, stainless, cast iron, and other ferrous metals, it delivers consistent results in high-production and maintenance environments alike. The optimized SL-4 double-cut geometry enhances chip control and reduces loading, allowing for smoother operation, less vibration, and improved surface finishes. Whether you're cleaning up welds, breaking edges, or shaping complex geometries, this bur is built to perform under pressure.

Key Features & Benefits:

• Conical Radius End Design – Ideal for smooth blending, contouring, and working on curved or irregular surfaces
• SL-4 Double-Cut Geometry – Promotes fast material removal with reduced chatter and better operator control
• Precision Ground Cutting Edges – Ensures consistent performance and extended tool life
• Versatile Material Application – Effective on steel, stainless steel, cast iron, and other hard metals
• Improved Chip Evacuation – Minimizes loading and heat buildup for cleaner cuts and longer runtime
• Enhanced Surface Finish – Produces smoother results, reducing the need for secondary finishing
• Standard 1/4" Shank (3-1/4" OAL) – Compatible with most die grinders and high-speed tools
• Built for Industrial Use – Reliable performance in demanding shop and field applications

When performance, durability, and finish matter, RSD Technologies burs deliver the edge your operation needs.
