KASAFE 10Pcs 90mm Magnetic Impact Driver Bits Set，S2 Steel Phillips Pozidriv and Torx Screwdriver Bits Set, Multi-Size Durable Design for Heavy-Duty Use, Universal 1/4" Hex Shank for Power Drivers

• 【Cryogenically Treated S2 Steel】S2 steel treated at -196°C enhances grain structure, delivering 15% higher toughness than standard heat-treated bits (KASAFE material lab data), resisting chipping in aluminum and steel applications
• 【High-Magnetic Triple-Drive Combination】Includes T15/T20/T25/T30 (Torx for high-torque machinery), PZ2 (Pozidriv for precision equipment), and PH2 (Phillips for general installation), adapting to anti-slip, precision, and universal fastening needs
• 【Dual Torsion Zone for Impact Resistance】Bit tip and shank dual torsion zones absorb 40% of peak torque (KASAFE testing), balancing 90mm length for optimal depth and durability in common tasks like plumbing and ceiling fixture installation
• 【Optimal Mid-Length Design】90mm length fits 80% of standard applications (KASAFE depth simulation), reducing tool switching for tasks like appliance repair and pipe fitting, improving efficiency by 40%
• 【Portable Transparent Plastic Case】White transparent case with drive-type and red rubber strips labeled with models, compatible with tool rack hooks or belt clips for quick access on job sites
