Product Description

Egg Shape Tungsten Carbide Bur, Aluminum Cut - 1/4" Shank

Black Hawk Abrasives Egg Shape Tungsten Carbide Bur, Aluminum Cut with 1/4" Shank is designed for vibration-free precision cutting, fast stock removal, and long useable life. These carbide rotary burrs feature precision ground flutes cut from premium tungsten carbide using five axis CNC machines. The flutes are affixed to the 1/4” shank during a soldering and sintering process that uses silver, which preserves the cobalt content thus increasing each burrs lateral strength and durability.
These die grinder bits are SE oval shape with nonferrous cut flute. SE oval/egg shape burs can be used for a wide variety of applications but excel at contouring, especially in confined, hard to reach areas. Aluma cut means the flutes are designed with a single, wide flute to ensure fast stock removal with ease and minimal loading. Aluminum cut rotary files like these are the ideal choice for softer materials such as aluminum, brass, copper, carbon fiber, magnesium, zinc, plastic, and many other non-ferrous materials.
These tungsten carbide burrs with 1/4-inch shank diameter attach to pencil grinders, die grinders or rotary grinders (electric or pneumatic).
