Multiple cutting edges on an SDS Plus drill bit have several beneficial effects on its drilling performance and efficiency, especially when drilling into tough materials like concrete, masonry, and stone. These cutting edges, often referred to as flutes or grooves, contribute to the overall effectiveness of the drill bit in the following ways:
Faster Drilling Speed: The presence of multiple cutting edges allows the drill bit to engage with the material more efficiently, resulting in a faster drilling speed. With each rotation of the drill bit, multiple cutting edges simultaneously chip away at the material, reducing the time required to create a hole.
Improved Chip Removal: The flutes or grooves created by the multiple cutting edges help facilitate the removal of debris, dust, and fragments from the drilling area. This prevents clogging and ensures smoother progress, reducing the risk of overheating and enhancing the overall drilling process.
Reduced Friction and Heat: The distribution of cutting load across multiple edges helps distribute the heat generated during drilling. This reduces the heat concentration on a single point, which can lead to less friction, longer tool life, and reduced wear on both the drill bit and the rotary hammer drill.
Enhanced Stability: The presence of multiple cutting edges helps stabilize the drill bit during drilling. As each edge engages with the material, it helps prevent wobbling or wandering, resulting in a more accurate and precise drilling process.
Optimized Cutting Action: Multiple cutting edges allow the drill bit to engage the material from different angles, optimizing the cutting action and reducing the amount of force required for drilling. This can lead to less strain on the drill and the operator.
Smaller Chipping and Splintering: When drilling into brittle materials like concrete or masonry, the presence of multiple cutting edges can help reduce chipping and splintering around the hole's edges, resulting in cleaner and neater holes.
Versatility: Multiple cutting edges make SDS Plus drill bits versatile for a range of drilling applications. They can be effective for drilling into various materials and hole sizes, providing adaptability to different tasks.
