Punch Driver Jonnesway Wybijak 4 x 150 mm M63104, steel shaft, straight punch

Jonnesway Wybijak 4 x 150 mm M63104 is a straight punch driver with a 4 mm diameter steel shaft and a 150 mm working length. Designed for driving pins, dowels and removing rivets, this tool provides a narrow profile for access into tight or recessed areas. The straight steel shaft offers rigidity and accurate force transfer for alignment and disassembly tasks in automotive, mechanical and general workshop applications.

Advantages

The straight steel shaft delivers consistent impact transmission and resists bending under typical workshop loads. Its 4 mm diameter and 150 mm length balance reach and control, allowing precision striking in confined spaces. The hardened tip maintains shape under repeated use and helps prevent mushrooming, while the compact profile reduces interference when working near adjacent components.

Suitable for

• Driving or removing small pins and dowels
• Removing rivets and cold chisel tasks on soft joints
• Aligning holes and positioning components during assembly
• Use in automotive, machinery maintenance and general workshop repairs

Key specifications

• Shaft material: steel
• Shaft diameter: 4 mm
• Working length: 150 mm
• Tool type: straight punch driver
• Tip: hardened for impact use

How to use

Select the punch driver for a shaft diameter appropriate to the pin or rivet to be removed. Position the hardened tip against the head of the fastener or the end of the dowel, ensuring alignment with the axis of the part. Strike the blunt end of the punch with a hammer in controlled blows to drive the pin or dislodge the rivet; for alignment tasks, use light taps until the component moves into the correct position. Maintain a secure grip on the tool and keep the workpiece supported to prevent slips or damage.

Usage recommendations

Wear eye protection when striking metal parts. Avoid using the punch on hardened fasteners beyond its design limits. Inspect the tip for deformation before use and regrind or replace the tool if the tip is mushroomed to reduce the risk of chipping or fragments.
