Wiha 75965 65-piece Micro Screwdriver Insert Bit Set

Product Description

The WIHA 75965 is a 65-piece micro screwdriver insert bit set designed for precision fastening work across a wide range of drive types and sizes. The set includes Torx, hex, Phillips, slotted, and Pentalobe bits, along with a 72-tooth ratchet handle, magnetic 1/4-inch to 4 mm adapter, micro bit extension, and precision handle. Hex sizes span 0.70 mm to 4.00 mm, and Torx sizes cover T-3 through T-20, making this a comprehensive kit for technicians who work on small-form-factor assemblies, electronics enclosures, and precision mechanical systems. The full set weighs 1.16 pounds.

This bit set is suited for electronics technicians, HVAC controls technicians, electricians, and field service professionals who regularly encounter fine-pitch fasteners on circuit boards, control modules, panel enclosures, and instrumentation. The included ratchet handle and bit extension improve access in confined spaces where a standard screwdriver cannot reach. The variety of drive types in a single kit reduces the number of individual tools a technician needs to carry to a service call.

Key Features

• 65 pieces total: 10 Torx bits, 16 hex bits, 16 nut drivers, 4 Phillips bits, 6 Pentalobe bits, 9 slotted bits, plus ratchet, adapter, extension, and handle
• Torx range T-3 through T-20 covers the most common micro and standard Torx fasteners
• Hex sizes from 0.70 mm to 4.00 mm (0.05 inches through 9/64 inches) for metric and imperial applications
• 72-tooth ratchet mechanism allows fine-increment turns in tight working spaces
• Magnetic 1/4-inch to 4 mm adapter included for secure bit retention
• Pentalobe bits included for service work on consumer electronics and specialty assemblies

Compatibility

Designed as a general-purpose micro bit set compatible with standard 1/4-inch and 4 mm bit-holder handles and ratchets. Bit selection covers fastener types commonly found in HVAC control boards, low-voltage electronics, electrical enclosures, and precision mechanical assemblies.

Installation Notes

Always de-energize and lock out equipment before opening electrical enclosures or control modules to access fasteners. Use the appropriate bit size to avoid camming out and damaging fastener heads, particularly on micro Torx and Pentalobe fasteners. This set is intended for hand-torque use only; do not mount bits in power drivers without verifying bit shank compatibility and appropriate torque limits for the fastener application.
