Nattools Watch Strap Hole & Notch Puncher (Manual & Pneumatic)

Product Overview

Nattools Professional Watch Strap Buckle Punching Machine Independently designed since 2015

This specialized tool is engineered for professional watch strap makers. It is designed to punch the oblong “tongue” or “pin” holes in watch straps with extreme precision. Unlike standard punches, this machine uses a shearing action to create a clean, vertical cut without any taper, ensuring a perfect finish on high-end leather straps.

Key Features

• Precision Shearing: Delivers a clean, sharp cut with zero taper (vertical edges), superior to traditional hammering punches.
• Versatile Use: Can be used directly on finished straps.
• Perfect Centering: Compatible with the NT32 Strap Making System for easy and accurate centering of the hole.
• High Efficiency: Greatly speeds up the workflow for small-batch or professional strap production.
• Durability: Cutters are made from high-quality die steel, rated for over 1,000 cuts when used correctly.

⚠️ Usage & Maintenance Guide (Important)

Please read before use to ensure longevity of the tool.

1. Shipping Adjustments: The fastening screws may loosen or shift slightly due to vibration during transport. Please inspect and adjust the alignment before your first use.
2. Blade Alignment: If the cutter “bites” or sticks, do not force it. Re-adjust the position of the bottom disc.
3. Thickness Limit: This tool is designed for precision work. Do not punch leather thicker than 3mm.
4. Lubrication: If the sliding mechanism feels stiff or has resistance, apply a small amount of lubricating oil to the guide pillars.
5. Edge Finishing: While the cut is precise, some leather types (like soft cowhide) may have slight fuzz after cutting. This is normal and can be treated easily with edge paint or a burnishing machine.
6. Spare Parts: Replacement cutters and screws can be purchased separately if needed.
7. Dedicated Use: This is a specialized tool. Do not use it for materials other than leather watch straps.
