COMP Cams POW353756 Carbide Burr 6" Ball Aluminum Cut Rotary Tool Bit

The COMP Cams POW353756 is a 6" Ball-Cut Carbide Burr designed specifically for aluminum cutting and porting applications. Featuring an aluminum cut (AL cut) tooth geometry, this burr is engineered to remove material efficiently from aluminum and other soft metals without clogging or loading up — a common problem when using standard double-cut burrs on non-ferrous materials.

Key Features:

• AL Cut (Aluminum Cut) Geometry: Single-flute spiral tooth pattern optimized for aluminum, magnesium, copper, and other soft/non-ferrous metals
• Ball Profile: Spherical head shape ideal for contour work, blending ports, and accessing curved or concave surfaces
• 6" Overall Length: Extended reach for deep porting and hard-to-access areas in cylinder heads and intake manifolds
• Solid Carbide Construction: Provides long tool life, resistance to heat buildup, and consistent cutting performance
• 1/4" Shank: Compatible with standard die grinders, rotary tools, and porting equipment

This carbide burr is a trusted tool among engine builders and performance enthusiasts performing cylinder head porting, intake manifold work, and custom fabrication on aluminum components. The aluminum-cut geometry prevents material from welding to the cutting edges, delivering smooth, clean material removal on every pass.
