The Mechanic 0.3mm Tungsten Steel Knife with a 2.35mm shank is a professional-grade precision tool primarily designed for micro-soldering, PCB repair, and delicate craftwork. It is widely used in the electronics repair industry for tasks like removing underfill (black glue), cutting traces, and cleaning IC pads.
Here is the comprehensive product description organized for clarity.
This tool is engineered for technicians who require extreme precision. Tungsten steel (wolfram steel) is chosen for its exceptional hardness and heat resistance, ensuring the blade remains sharp even under repetitive stress or high-heat environments.
The following table outlines the core physical and material properties of the knife.
| Feature | Specification Details |
| Product Name | Mechanic Tungsten Steel Precision Knife |
| Blade Material | High-Grade Tungsten Steel (Wolfram) |
| Tip Diameter | 0.3mm (Ultra-Fine) |
| Shank Diameter | 2.35mm (Standard universal fit) |
| Hardness | HRC 85-90+ |
| Corrosion Resistance | High / Oxidation Resistant |
| Compatibility | Rotary tools, micro-drills, or dedicated hand-chucks |
| Primary Use | Underfill removal, PCB trace cutting, IC cleaning |
Superior Hardness: Made from industrial-grade tungsten steel, the blade is significantly harder than standard stainless steel, preventing the tip from dulling quickly.
0.3mm Ultra-Fine Tip: Specifically designed for "surgical" precision on motherboards where components are spaced less than a millimeter apart.
High Temperature Stability: Maintains structural integrity when working near hot air stations or soldering irons.
Standard 2.35mm Shank: This is the industry standard for dental drills and electronics polishing pens, making it a "plug-and-play" accessory for most professional rotary tools.
