The GRENPRO 22-piece Allen wrench drill bit set is a handy upgrade for anyone who wants faster hex screw driving with a drill or impact driver. Each bit is 2 inches long with a 1/4″ quick-release hex shank, making swaps quick and straightforward when you’re moving between sizes.

This set includes both Metric and SAE hex sizes, so you can cover common household, automotive, and general project needs without juggling multiple kits. The bits feature a torsion zone designed to absorb torque peaks and help reduce breakage during tougher driving tasks.

Built with CNC-machined tips and an S2 alloy steel body, these bits are made for precision fit and durability. A strengthened magnetic design helps hold screws more securely during use, and the manganese phosphate surface is intended to help resist rust.

  • 22-piece set with both Metric (1.5–8 mm) and SAE (5/64″–5/16″) sizes
  • 2″ long bits with 1/4″ quick-release hex shank for fast changes
  • Torsion zone designed to absorb torque peaks to help avoid breakage
  • Strong magnetic, high-precision fit to help lock onto screws
  • CNC-machined tips, S2 alloy steel body, manganese phosphate surface to help prevent rust

If you want an affordable, all-in-one hex bit kit for impact driving and everyday maintenance, this GRENPRO set delivers broad size coverage in a compact 22-piece package.
