Chasse-goupille Bahco 3659-1.4

The Bahco 3659-1.4 drift punch is a compact alignment and pin-driving tool designed for precision tasks. Constructed from durable steel with a stainless steel handle, it measures 85 mm in length and weighs approximately 10 g. Its small size and balanced weight make it suitable for fine manual work where controlled force and accuracy are required.

Advantages

This drift punch offers corrosion-resistant stainless steel handling combined with a hardened steel shaft for wear resistance and reliable performance. Its lightweight construction reduces hand fatigue during repetitive tasks while the compact 85 mm length enables access to confined spaces. The tool's slender profile supports precise alignment of pins, rivets and small fasteners without excess material removal.

Suitable for

• Precision alignment of pins and dowels in mechanical assemblies
• Driving small nails and pins in woodworking and light metalwork
• Removal or repositioning of retaining pins and cotter pins
• Accessing tight or recessed areas where a full-size punch is impractical

Key specifications

• Overall length: 85 mm
• Weight: approx. 10 g
• Material: hardened steel shaft with stainless steel handle
• Tip type: drift punch (slender alignment tip)

How to use

Hold the drift punch by the stainless steel handle and position the tip against the pin, nail or component to be aligned. Apply controlled taps with a hammer or mallet to drive or shift the pin as required, taking care to maintain alignment and avoid bending the workpiece. For removal tasks, work incrementally from both sides if possible to prevent jamming. After use, clean the tool to remove any debris and store it in a dry place to preserve the stainless handle and the hardened shaft.

Recommendations

Use appropriate eye protection and choose a hammer or mallet suitable for the size of the punch. Avoid excessive force that could mushroom the tip or damage delicate components; if greater force is required, consider a larger punch or proper press equipment. Regularly inspect the punch tip for wear and replace if deformed to maintain safe and accurate operation.
