✨ Core Features
Double-edged ball head design:
Compared to single-edged, cuts more smoothly, feed rate is higher, and machining efficiency is improved.
The ball head tip can achieve high-precision machining of 3D curved surfaces, arcs, and chamfers.
Standard 1/8 Shank Size:
3.175mm is a universal shank diameter for CNC engraving machines and PCB engraving machines, offering excellent compatibility.
Small Diameter Cutting Edge:
1.5mm fine cutting edge suitable for precision machining, small letter engraving, and thin-walled part processing.
Individual Packaging:
Single transparent plastic box + blue shockproof protective sleeve to prevent cutting edge damage during transportation/storage.

III. Packaging and Specifications
As seen in the actual photos:
1 piece per box, 10 boxes/pack (two stacks, 5 boxes per stack), 10 pieces per pack.
Outer packaging uses bubble wrap + Plastic sealed for strong protection, suitable for bulk purchases.
Standardized labeling facilitates warehouse management.
IV. Selection and Usage Tips
🔧 Selection Recommendations
For machining high-gloss materials such as acrylic, a mirror-polished coating is recommended to improve surface finish.
When machining metals, prioritize carbide + AlTiN coating for enhanced wear resistance.
A 1.5mm cutting diameter is a precision machining tool, unsuitable for deep cuts or high-load roughing.
⚠️ Usage Precautions
Use a high-precision chuck during installation to ensure coaxiality and prevent tool vibration.
Recommended speed for machining acrylic: 18000-24000 rpm, feed rate: 1000-2000 mm/min.
Use cutting fluid for machining aluminum parts to prevent chip adhesion.
Avoid edge collisions during storage; clean and prevent rust after use.
