What's Included

• 4 × Right Angle Screwdriver Adapters (90°)
• 1 × 300mm Flexible Extension Shaft
• 10 × Multi-specification Screwdriver Bits (Slotted, Hex, Torx & more)

Key Features

🔩 Extreme Durability — 56–58 HRC Hardness

Every bit and adapter is forged from premium High Chromium Alloy Cast Steel (HCS) with quenching heat treatment, achieving 56–58 HRC hardness. This delivers up to 10× longer service life than standard carbon steel tools, resisting abrasion and deformation even under heavy torque loads.

📐 90° Right-Angle Design for Narrow Spaces

The precision-cast 90-degree right-angle structure fits effortlessly into tight gaps, corners, and recessed positions — think cabinet cavities, engine compartments, ceiling corners, and furniture undersides — where a standard screwdriver simply can't go. Saves up to 60% of your repair time by eliminating the need to disassemble surrounding components.

⚙️ Rock-Solid Torque Transmission

A precision-machined 1/4" universal hex interface locks bits and drill shanks firmly in place — no slipping, no stripped screws. Ensures 100% torque transfer for improved accuracy and operational safety.

🛡️ Corrosion & Rust Protection

All metal parts receive a chrome plating or black oxidation coating that forms a dense Cr₂O₃ passivation film on the surface. This shields against oil, moisture, and mild acid/alkali environments — ideal for construction sites and garage workshops — with virtually zero daily maintenance required.

🔧 Wide Compatibility — Works with Drills & Manual Use

All 10 included HCS bits are compatible with slotted, hex, and Torx screws across common sizes. Paired with the 300mm flexible extension shaft, the kit supports both electric drill and manual operation, covering furniture assembly, appliance repair, automotive maintenance, and all your home DIY needs.

✋ Ergonomic Non-Slip Grip

The handled right-angle screwdriver features an HCS internal transmission structure combined with a non-slip ABS grip, making manual operation comfortable and effort-efficient — even during extended use sessions.

Frequently Asked Questions

Q: What drill shank size does this screwdriver bit kit use?

A: All adapters and bits in this kit use the standard 1/4" hex shank, which is compatible with the vast majority of cordless drills, impact drivers, and drill presses. The universal hex interface also supports manual screwdriver use.

Q: Can I use the flexible extension shaft with an electric drill?

A: Yes! The 300mm flexible extension shaft supports both electric drill and manual operation. It's specifically designed to transmit torque around bends, giving you access to fasteners in angles and spaces that a rigid drill bit cannot reach.

Q: What types of screws are the included bits compatible with?

A: The 10 included HCS screwdriver bits cover slotted, hex (Allen), and Torx screw heads across the most common sizes, making this kit suitable for furniture assembly, appliance repair, automotive work, and general home DIY projects.

Q: How durable are the right-angle adapters compared to standard tools?

A: The right-angle adapters are made from High Chromium Alloy Cast Steel (HCS) with quenching heat treatment, achieving a hardness of 56–58 HRC. This makes them significantly more wear-resistant and longer-lasting — up to 10× the service life of ordinary carbon steel tools — even under heavy repeated use.
