Internal Grooving Tool Holder

An Internal Grooving Tool Holder is a specialized cutting tool holder designed to create grooves within the internal diameter of a workpiece, such as inside a bore or a pipe. Unlike external grooving, this operation requires the tool holder to access confined spaces, making its design crucial for stability and reach. These holders are engineered to securely clamp and support small grooving inserts, ensuring precise groove dimensions and a good surface finish inside the bore.

Due to the limited space, internal grooving tool holders often feature slender shanks and optimized head designs to provide sufficient clearance and minimize the risk of collision with the workpiece. They come in various sizes and configurations to accommodate different bore diameters and groove specifications, ranging from small diameter internal grooves to larger ones. ¹ Some internal grooving tool holders may also incorporate features for internal coolant delivery, which aids in chip evacuation and improves tool life in these challenging machining environments.

Choosing the correct internal grooving tool holder is vital for achieving accurate and efficient internal grooving operations. Factors like the bore diameter, the required groove width and depth, and the material of the workpiece all play a significant role in the selection process. A well-designed internal grooving tool holder contributes to increased productivity, improved groove quality, and reduced tool breakage when working within the constraints of an internal bore.
