The MFD Series (Multi-Function Drill Bit) is built for pros who need versatility and durability in one tool. Designed to handle a wide range of materials, these bits power through cinder block, marble, roof tile, glass, concrete, sand-lime brick, masonry, asphalt, mortar, plastic, and more. A diamond-ground carbide tip ensures precise, efficient drilling, while the wide helix promotes fast chip removal and smooth performance. The shot-peened surface treatment enhances break resistance, making these bits ideal for demanding, repetitive tasks. Each bit also features a 3-flat shank for a secure hold in your chuck, reducing slippage during use. With optimized carbide geometry and an enlarged point angle, MFD Series bits deliver long-lasting reliability across multiple applications—perfect for rotary drilling where performance and flexibility matter most.
