COMP Cams POW355306 Solid Carbide Burr 6" Cylinder with Radius 1/4" Shank

The COMP Cams POW355306 is a solid carbide burr featuring a cylinder with radius (end) profile on a 6" long, 1/4" straight shank. Designed for precision porting, deburring, and material removal, this burr is an essential tool for engine builders and machinists who demand consistent, controlled results on cylinder heads, intake ports, and other performance engine components.

Key Features:

• Solid carbide construction for superior hardness, heat resistance, and edge longevity
• Cylinder with radius end profile — ideal for blending, contouring, and porting curved or radiused surfaces
• 6" shank length provides extended reach for deep port work and hard-to-access areas
• Precise 1/4" straight shank fits standard die grinders and rotary tools
• Suitable for use on cast iron and aluminum engine components
• Delivers a small, controllable cut — ideal for finish grinding and fine detail work

COMP Cams offers one of the most complete lines of solid carbide burrs available, covering a wide variety of shapes, sizes, and cut styles to handle any porting or metal removal task. For finish grinding work on aluminum, apply silicone spray lubricant to the tip periodically to prevent material load-up and maintain cutting efficiency.
