Suitable for

• Removing cylinder pins, spring pins and small dowels
• Driving out rivets in tight or confined spaces
• Locksmith and precision mechanical disassembly
• Maintenance, repair and assembly tasks requiring targeted impact

Key specifications

• Tool type: Handheld cylinder punch
• Material: Hardened steel striking tip and shank for wear resistance
• Design: Single-piece construction for durability
• Size class: Compact length suitable for confined spaces
• Intended use: Driving out cylindrical fasteners such as pins, rivets and dowels

How to use

Position the punch tip centrally on the end of the pin, rivet or dowel to be removed. Use a hammer with controlled strikes to drive the fastener out, keeping the punch aligned with the axis of the pin to avoid bending or damage. For pins seated deeply, use progressive strikes and verify alignment frequently. After use, inspect the striking surface and shank for deformation before storing.

Usage recommendations

Use personal protective equipment such as safety glasses and gloves when striking. Match punch size and tip diameter to the fastener to minimize surface damage. Avoid using the punch on hardened pins that exceed the tool's material hardness to prevent tip mushrooming; replace or regrind the tip if deformation is detected.
