Knipex 9R400022 22 Pc Punch and Chisel Set

The Knipex 9R400022 is a 22-piece punch and chisel set for shop, maintenance and repair work. The set covers cold chisels, center punches and pin punches, so it handles metal cutting, marking and pin driving.

Key Features:

• Octagonal shafts are easier to grip when striking with a hammer and keep the tool from rolling off a work surface
• Material core design helps prevent mushrooming of the striking head
• Hardened to 54 to 58 HRC along the full length of each tool, not just at the tip
• Complies with the DIN 7255 standard
• Chisels have a hand-ground edge made to cut and shear cold metal
• Striking heads are turned and chamfered, and all edges are rounded to protect the workpiece

Typical uses: Center punches mark a drill point precisely and guide the drill bit. They also make permanent location marks when disassembling engine parts. Pin punches drive pins out of holes and help install them.

The set is sold under the Rennsteig name, which is part of the Knipex Group.
