Hole Enlarging Drill Bits These bits are designed to enlarge existing holes to the required diameter for hardware, fittings, or components. For precise parameters, please refer to the second picture of the variant. Key benefits - Enlarge holes to fit larger bolts, screws, pins, or fittings without starting over - Produce clean, accurately sized holes with minimal rework - Streamline projects by using a single bit for hole enlargement instead of multiple tools - Variant specific details such as diameter and shank are shown in the second image Core attributes - Function: enlarges existing holes to the final size needed - Compatibility: parameters and exact fit are variant dependent; see the second image for specifics - Size: exact diameter and other size-related details vary by variant; check the second image for precise numbers - Material and performance: detailed material information and performance characteristics are provided in the variant second image Use scenarios - Scenario 1: Rework an existing mounting hole in a metal or wooden frame to accommodate a larger bolt or pin during repair or retrofit - Scenario 2: Create a clearance hole for electrical conduits, grommets, or tubing during equipment installation or cabinet wiring - Scenario 3: Modify furniture, cabinetry, or machinery housings to fit new hardware or connectors that require a bigger hole Usage guidance - Use appropriate drilling speed and feed according to the material - For metal drilling, apply suitable lubrication to reduce heat and wear - Secure the workpiece and wear appropriate eye protection during operation Note - See the second picture for the precise parameters of the variant you choose, including diameter, shank, and other measurements.
