Roll Pin Punch is a precision hand punch built for removing roll pins without damaging the pin or the surrounding part. This is a roll pin punch designed for pin removal in repair, assembly, and maintenance work. Model Number: 9R 455 721 KUS. If you work on machinery, equipment, metal parts, or detailed assemblies where a standard flat punch can slip, this size-specific punch gives you a cleaner, more controlled hit.\u003c\/p\u003e\n    \u003cp\u003eWhat matters here is the tip design. Instead of a plain end, the center of the tip has a rounded pilot that fits into the hole created by the roll pin. That keeps the punch centered as you strike it, which helps reduce walking, edge damage, and bent pins. On small pins like 3\/32 in., that extra control is the difference between a quick removal and a frustrating mess.\u003c\/p\u003e\n    \u003cp\u003eThe body is forged from hardened chrome vanadium steel and tempered to 54 to 58 HRC through the entire length, not just at the working end. That matters because repeated hammer blows do not just stress the tip. They travel through the whole tool. Full-length hardening helps the punch hold shape, resist wear, and stand up to regular shop use better than lighter-duty punches that are only hardened at the end.\u003c\/p\u003e\n    \u003cp\u003eRennsteig also built this punch with practical shop details that are easy to appreciate once you use it. The octagonal body gives you a better grip when you are lining up on a small pin, and it helps keep the tool from rolling off a cart or bench. The ground and polished tip improves fit and consistency at the working end, and the core design is made to resist mushrooming at the striking head over time.\u003c\/p\u003e\n    \u003cp\u003eAt 6 in. overall length, this punch gives you enough reach to work in tighter spots while still keeping your hand a safer distance from the hammer face. The slim 3\/32 in. tip diameter makes it a good fit for smaller roll pins where accuracy matters more than brute force. It also complies with DIN 7255, which gives added confidence that the dimensions and form are made to a recognized standard.\u003c\/p\u003e\n    \u003cp\u003eThis punch makes the most sense for mechanics, metalworking shops, equipment maintenance crews, gunsmithing-style bench work, and serious DIY users who need a proper roll pin punch instead of making do with a generic drift. If you regularly remove spring pins and want cleaner starts, better alignment, and longer service life, this is the right kind of simple tool to buy once and keep in the box for years.\u003c\/p\u003e\n  \u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails id=\"product-at-a-glance\" class=\"acc\"\u003e\n  \u003csummary\u003e\u003ch2\u003eAt a Glance\u003c\/h2\u003e\u003c\/summary\u003e\n  \u003cdiv class=\"acc-body\"\u003e\n    \u003cdiv class=\"stats-grid\"\u003e\n      \u003cdiv\u003e\n        \u003cdiv class=\"stat-value\"\u003e3\/32 in.\u003c\/div\u003e\n        \u003cdiv class=\"stat-label\"\u003eTip Diameter\u003c\/div\u003e\n      \u003c\/div\u003e\n      \u003cdiv\u003e\n        \u003cdiv class=\"stat-value\"\u003e6 in.\u003c\/div\u003e\n        \u003cdiv class=\"stat-label\"\u003eOverall Length\u003c\/div\u003e\n      \u003c\/div\u003e\n      \u003cdiv\u003e\n        \u003cdiv class=\"stat-value\"\u003e54-58 HRC\u003c\/div\u003e\n        \u003cdiv class=\"stat-label\"\u003eHardness\u003c\/div\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails id=\"product-benefits-1\" class=\"acc\"\u003e\n  \u003csummary\u003e\u003ch2\u003eStay Centered on Small Roll Pins\u003c\/h2\u003e\u003c\/summary\u003e\n  \u003cdiv class=\"acc-body\"\u003e\n    \u003cdiv class=\"row\"\u003e\n      \u003cdiv class=\"img\"\u003e\n        \u003cimg src=\"https:\/\/cdn.anglera.com\/assets\/74d6ed76-fe0d-4d23-a9db-1f8749ca9ef2\/2026052183_1.jpg\" alt=\"Knipex Rennsteig 9R 455 721 KUS 3\/32 in. x 6 in.
