25168 - Pferd SL-5 Carbide Burr INOX Cut 1/2" x 1-1/8" - 1/4" Shank

Precision Grinding for Stainless Steel Applications

The Pferd 25168 Carbide Burr represents the pinnacle of German abrasive engineering, specifically tailored for the demanding requirements of working with stainless steel (INOX). Part of Pferd's High Performance Line, this tool addresses the common frustrations associated with grinding austenitic, rust-resistant, and acid-resistant steels. Standard carbide burrs often struggle with the toughness of stainless steel, leading to heat generation, glazing, and rapid tool wear. The 25168 utilizes a specialized INOX cut geometry that features a high cutting volume, allowing for aggressive stock removal while maintaining a cooler grinding temperature.

The tool features an SL-5 shape, which is a tapered cone with a radius end and a 14-degree included angle. This specific profile is exceptionally versatile, allowing operators to grind contours, access tight corners, and work on fillet welds with precision. The 1/2-inch diameter and 1-1/8-inch length of cut provide a substantial working surface area, making it efficient for both heavy material removal and fine detailing. The radius end is particularly useful for blending radii and preventing gouging in sensitive areas.

Technical Superiority and Efficiency

One of the critical technical benefits of the INOX cut is the reduction of thermal stress on the workpiece. Excessive heat during grinding can alter the microstructure of stainless steel and lead to corrosion issues or unsightly discoloration (heat tint). By cutting more efficiently, the Pferd 25168 minimizes dwell time and friction, preserving the integrity of the base material. Furthermore, the precision manufacturing of the tungsten carbide head ensures concentricity, resulting in lower vibration levels. Reduced vibration not only extends the life of the die grinder bearings but also reduces operator fatigue during extended shifts, leading to more consistent and higher-quality finishes.

Designed with a standard 1/4-inch steel shank, this burr is compatible with a wide range of pneumatic and electric drive systems. For optimal performance, it is recommended to use this burr at the manufacturer's suggested RPM ranges, which ensures the teeth engage the material correctly without chattering. Whether used in aerospace, food processing equipment manufacturing, or chemical plant maintenance, the Pferd 25168 delivers reliable, high-performance results on difficult-to-machine stainless alloys.
