1/8" X 3-3/8" MFD Series Multi-Material Carbide Tip Drill Bit

• Drills Multiple Materials: Engineered to cut through cinder block, marble, roof tile, glass, concrete, sand-lime brick, masonry, asphalt, mortar, plastic, hollow brick, tile, and more, the MFD Series offers unmatched versatility on the job, reducing the need to switch bits between tasks.
• Durable Carbide Tip: Precision diamond-ground carbide tip provides clean, efficient drilling and holds up to repeated use in tough materials.
• Fast, Efficient Performance: Wide helix design promotes rapid chip removal and smooth operation, boosting productivity with every hole.
• Built to Last: Shot-peened surface and optimized carbide geometry with an enlarged point angle deliver superior break resistance and a longer working life.
• Secure 3-Flat Shank: Equipped with a 3-flat shank for a firm grip and reduced slippage in the chuck, ensuring better control and torque transfer during drilling.

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.
