40 in 1 Ratchet Screwdriver Set with Detachable Handle, 180° Ratchet Head, 45-Tooth Mechanism, Magnetic Tool Kit with Case for Computer, Electronics Repair

This 40-in-1 multi-functional tool set can be called an "all-round assistant" in the field of professional maintenance. Its core advantage stems from the ultimate pursuit of materials — crafted with high-quality S2 alloy and CRV steel, it fundamentally ensures the lifelong durability of the tool. Whether it is daily maintenance or high-intensity operations, it can perform stably. The set includes 28 S2 alloy bits, covering the four most commonly used specifications in maintenance scenarios: Phillips (PH), Slotted (SL), Torx, and Hex. Each bit undergoes precision processing to ensure a tight fit with screws and bolts, preventing slipping and damage to workpieces. Additionally, there are 9 CRV chrome-plated sleeves with a special anti-rust coating on the surface. This coating not only resists corrosion from harsh environments such as moisture and oil stains, extending the service life, but also ensures a smooth feel during repeated installation and removal.

• 180° Universal Ratchet Head & 45-Tooth Precision Mechanism - Tackle Tricky Angles in Confined Spaces. The zinc alloy ratchet head pivots 180° with one-hand control, paired with 45-tooth (8° micro-rotation) precision mechanism to access tight spaces like electronics/bicycle repairs - outperforms standard 24-tooth ratchets.
• Magnetic Extendable Handle & Detachable Rod - Deep Hole Access with Zero Slip. Aluminum extension rod (+4.7" reach) and triple-magnetic connections (handle/rod/head) ensure secure grip for deep screw removal in appliances/furniture assembly.
