Overview

Meet the GRENPRO Torx Bit Set, a 14-piece collection designed for reliable grip, bold torque, and extended tool life. Each bit is precision-crafted for impact drivers, drills, and screwdrivers, delivering confident performance without sacrificing everyday usability. The set includes tamper-proof Torx sizes from TT7 through TT40, with duplicates where the larger fasteners demand extra bite.

What’s in the kit

  • TT7, TT8, TT9, TT10, TT15, TT20 x2, TT25 x2, TT27, TT30, TT35, TT40 — a complete range for common fasteners
  • 1/4 in impact driver bit set with a retention hole for easy storage and quick changes

Why it stands out

  • Torsion zone helps absorb torque peaks to reduce breakage during high-torque tasks
  • Fifteen times life expectancy versus standard bits, providing more work per set
  • Magnetic star bits ensure easy pick-up and steady screw alignment without misalignment or dropped screws


Build and versatility

  • Black, precision CNC-machined tips on S2 alloy steel bodies for enhanced strength and longer life
  • Hardened cores tolerate demanding jobs and reduce wear over time
  • Externally coated protective cover adds anti-rust protection for long-term use

Designed for home repairs, automotive tasks, woodworking, and other screw-driving applications, this kit pairs compact organization with robust performance. The included case keeps the bits neatly stored and ready for your next project.
