1/2" 12Pcs Impact Screwdriver Bit Set

Product Introduction

The 1/2" 12Pcs Impact Screwdriver Bit Set (BK-247003) is an indispensable professional tool engineered to free rusted, frozen, corroded, or over-tightened screws and fasteners with ease. By converting a hammer strike into high instantaneous rotational torque, this impact driver quickly breaks loose stuck bolts without damaging the screw head. Built with a high-grade Chrome-Vanadium (Cr-V) steel body and equipped with ultra-tough S2 impact bits, this heavy-duty set offers maximum force transfer and high resistance to wear.

Product Features

Premium Material: Manufactured from high-quality Chrome-Vanadium (Cr-V) steel with precision machining and professional heat treatment for ultimate hardness and durability.

Durable Construction: Sturdy, heavy-duty handle and drive system ensure long-lasting performance under high-impact hammering.

Stylish & Protective Finish: Features a unique electroplated surface finish that not only offers an attractive, high-end appearance but also provides superior rust and corrosion resistance.

High-Quality Components: Equipped with imported Chrome-Vanadium (Cr-V) steel couplers for 1/2" drive compatibility and tough S2 alloy impact bits for extreme torque resistance.

FAQ

Q1: How does a manual impact screwdriver set work?

A: When you strike the end of the driver handle with a heavy hammer, the force pushes an internal cam mechanism that forces the 1/2" drive bit to rotate instantly with tremendous torque, breaking loose rusted screw threads.

Q2: Can I remove the bit coupler to use standard 1/2" drive sockets?

A: Yes! The 1/2" square drive adapter (coupler) is detachable, allowing you to attach standard 1/2" impact sockets directly for heavy bolt removal.

Q3: Why are the bits made of S2 steel instead of standard Chrome-Vanadium?

A: S2 steel has higher silicon alloy content, offering superior toughness and shock resistance under heavy hammer impacts, preventing the tip from snapping compared to standard steels.

Q4: What is the MOQ (Minimum Order Quantity) for OEM customized orders?

A: Our standard MOQ for customized branding and color box packaging is 1,000 sets (50 master cartons).

Q5: Can I request a sample before placing a bulk order?

A: Yes! We are happy to supply samples for testing torque efficiency and material quality. Please contact our sales team to request samples.
