Description

Hex Bit, 1/4-Inch Drive, 50mm Length, 1.5mm Hex Tip

Brief Overview

This is a precision hex bit designed for exacting assembly and repair work where smaller hex fasteners are the standard. The 1.5mm hex tip makes this bit essential for fine mechanical work, electronics assembly, and light-duty precision applications. Your customers working with miniature components will appreciate the accuracy this bit provides. For shops stocking a complete hex bit range, pair this with larger hex tips like 2mm and 2.5mm options to cover the full spectrum of fine fastening work.

Key Features

  • 1.5mm Hex Tip: Small, precision-ground hex working end for miniature fasteners
  • 50mm Overall Length: Balanced tool length for controlled torque application in confined spaces
  • 1/4-Inch Hex Drive: Standard quick-change shank for universal compatibility with impact drivers, cordless drills, and manual hex drive handles
  • Machined Metal Construction: Durable grey-finished steel shaft with laser-etched markings for quick identification
  • Chamfered Transitions: Smooth edges at both ends reduce wear and prevent jamming in drive sockets

Why Resellers Choose This Bit

This is the bit for precision work—the kind of job where a slightly larger 2mm tip won't fit or will damage the fastener head. Shops specializing in fine mechanics, watch repair, jewelry work, or delicate electronics benefit from stocking this size. Low inventory cost, high perceived value to your professional customer base, and strong repeat demand make this a profitable stocking item.
