H HSS Tapered Reamer

The H HSS Tapered Reamer is a High-Speed Steel (HSS) Tapered Reamer specifically identified as the HSS Tapered Reamer H. This tool is used in the process of repairing cracks in castings, particularly in thick metal, by reaming the drilled hole prior to tapping for “H” series ductile iron plugs.

The H HSS Tapered Reamer is a High-Speed Steel (HSS) Tapered Reamer designed for preparing holes in castings for the installation of “H” series ductile iron plugs. Identified as the HSS Tapered Reamer H, this tool is particularly useful when repairing cracks in areas with substantial metal thickness.

In the casting repair process, this reamer is used after a pilot hole has been drilled (a 1 1/32 inch drill is specified for “H” plugs) and before the hole is threaded with a tap (the corresponding HSS Tapered Tap is Part # 407-5310-80). The purpose of reaming with a tapered reamer, especially in thicker metal sections, is to ensure a more accurate and appropriately sized hole for tapping, which helps to extend the life of the tapered tap.

The H HSS Tapered Reamer is specifically designed for use with the “H” series of ductile iron plugs, which includes the H Solid plug (452-2610-80), the H-2 Drilled plug (452-2610-82), and the H-4 Drilled plug (452-2610-84). The “H” plug has a small end diameter of 1.084 inches.

The reaming step with this tool is part of a larger sequence for casting repair, which typically involves drilling the initial hole, reaming it with the HSS Tapered Reamer, tapping the hole with the corresponding tap (407-5310-80), installing the ductile iron plug, cutting off any excess plug material, and peening, with our specially designed peening hammer kit (412-5911-00), the remaining plug to ensure a secure and sealed repair. It is recommended to use a quality tapping fluid, such as Irontite Tap-O (468-9920-08), during the tapping stage to facilitate smooth thread cutting.

The H HSS Tapered Reamer is a listed product from Irontite, essential for achieving durable and reliable repairs using the “H” series ductile iron plugs in various casting applications.
