## Description

Reach deep into engine intake manifolds, cylinder heads and other confined areas with this 5-piece, 4.3 in. long-reach tungsten carbide burr set. Each extended-length rotary burr features a 1/4 in. shank, providing the extra reach needed for professional metal porting, grinding, shaping and deburring in areas where standard bits cannot reach. The double-cut tooth pattern produces smaller chips and a finer finish for increased safety and improved control when working on cast iron, steel and aluminum. Built for demanding applications, these carbide burrs withstand high-speed rotation and resist bending when used with proper contact techniques. Ideal for automotive restoration, engine modification, metal fabrication and heavy-machinery maintenance, this versatile 5-piece kit provides dependable performance for detailed finishing and material removal.

• Universal 1/4 in. shank fits dremel and rotary tools
• 4.3 in. extended shafts reach deep into engine ports
• Double-cut design provides smooth, rapid material removal
