- When sourcing stone drill bits for hard rock wholesale, it's crucial to consider factors such as the type of rock, drilling depth, and expected workload. Suppliers often offer a range of sizes and designs to accommodate various drilling machines and projects. It's also essential to ensure that the bits are compatible with the existing drilling equipment and meet safety standards.
- Another popular shank type is the hex shank. Hex shanks have six flat sides that allow for a secure grip in a drill chuck, preventing slippage during use. This type of shank is commonly found on impact drivers and other power tools that require extra torque. The flat sides also make hex shanks easy to change out quickly, saving time on the job.
