Knipex 9R 455 007 7-Piece Roll Pin Punch Set Chrome Vanadium Steel

The Knipex 9R 455 007 is a 7-piece roll pin punch set engineered by Rennsteig — a member of the Knipex Group — for the precise installation and removal of roll pins in demanding professional and shop environments. Each punch is forged from hardened chrome vanadium steel and tempered to a hardness of 54–58 HRC along its entire length, not just at the tip, ensuring exceptional durability and long service life.

Key Features:

• Specialized rounded tip profile seats inside the roll pin bore to prevent deformation and simplify pin removal
• Octagonal body cross-section provides a positive grip when striking with a hammer and prevents the punch from rolling off work surfaces
• Solid-core construction resists mushrooming of the striking head under heavy use
• Tips are individually ground and polished for precision fit and clean engagement
• Complies with DIN 7255 standard
