Through CNC turning and milling high-precision processing, the bit and the screw can be engaged more closely, and it is not easy to damage the precision screw. Chemical anti-rust treatment enlarges service life and good using performance;
• Ergonomic Solid Handle - Made of alloy steel, lightweight and durable. Surface anodizing and knurled treatment make sure it's anti-sweat, anti-corrosion, and non-slip. The handle with a built-in extension shaft and a free-turning end-cap for better control;
