The KENNAMETAL 1099448 is a right-hand A-MDUN indexable boring bar designed for precision boring operations in heavy-duty machining applications. With a minimum bore diameter of 33.02mm and an overall length of 304.8mm, this tool is engineered to provide stability and accuracy in deep-hole boring tasks. The 1" shank diameter ensures a secure fit in standard tool holders, while the -3‚° lead angle facilitates efficient chip removal and improved surface finish. The through-coolant feature enhances tool life and performance by directing coolant directly to the cutting edge, reducing heat buildup and minimizing tool wear. This boring bar is compatible with A-MDUN inserts, offering versatility and ease of insert replacement. Ideal for applications requiring precise boring in medium to large diameter holes, the KENNAMETAL 1099448 delivers reliable performance and operational efficiency.
