SDS Plus drill bits are specifically designed to be effective for drilling into tough and hard materials such as concrete, masonry, stone, and brick. These drill bits offer several key features that enhance their drilling performance and efficiency in challenging applications:
Specialized Shank Design: The SDS Plus shank design is a key feature that sets these drill bits apart. The shank features grooves that allow for quick and secure insertion into the SDS Plus chuck of a rotary hammer drill. This design provides efficient power transfer and reduces slippage during drilling, ensuring maximum force is applied to the bit.
Tungsten Carbide Tip: SDS Plus drill bits often have a tip made from tungsten carbide, a hard and durable material that is well-suited for drilling into tough materials. Tungsten carbide tips can withstand high levels of heat and abrasion, allowing them to maintain their sharpness and cutting effectiveness even when drilling into hard surfaces.
Flute Design: The flutes on SDS Plus drill bits are engineered for effective debris removal. They help to quickly channel dust and debris away from the drilling area, preventing clogging and allowing for efficient drilling progress.
Reinforced Core: Many SDS Plus drill bits feature a reinforced core that adds strength and stability to the bit. This helps prevent bending or breaking, especially when drilling through thick or dense materials.
Spiral or Helix Design: The spiral or helix design of SDS Plus drill bits aids in smooth and efficient drilling. It allows for improved chip evacuation and reduces the amount of heat generated during drilling.
Hammer Action Compatibility: SDS Plus drill bits are designed to be used with rotary hammer drills that have a hammering or pneumatic action. This hammer action, combined with the drill's rotation, helps the bit penetrate tough materials effectively.
Vibration Damping: Many high-quality SDS Plus drill bits incorporate features to reduce vibration and impact stress on both the bit and the tool. This contributes to better operator comfort and longer tool life.
Variety of Sizes and Lengths: SDS Plus drill bits are available in a range of sizes and lengths to accommodate different drilling depths and hole diameters, making them versatile for various applications.
Multiple Cutting Edges: Some SDS Plus drill bits have multiple cutting edges, which can help distribute the cutting load and enhance drilling efficiency.
Durability and Longevity: The combination of tungsten carbide tips, reinforced cores, and other high-quality materials makes SDS Plus drill bits durable and capable of withstanding the demands of drilling into tough materials.
The combination of these features makes SDS Plus drill bits well-suited for heavy-duty drilling tasks in challenging materials, providing efficient drilling performance and helping to reduce wear on both the bit and the drill.
