Wiha 72593 Screwdriver Insert Bit Set 10 Piece

Product Description

The WIHA 72593 is a 10-piece screwdriver insert bit set covering three common drive types: Phillips, slotted, and square recess. It is designed for use with power tools, impact drivers, and manual bit holders that accept standard insert bits. The set includes four Phillips bits ranging from size 0 to 3, three slotted bits in 4.5, 5.5, and 6 millimeter widths, and three square recess bits in sizes 1, 2, and 3. The compact profile of each bit measures 0.38 inches in length, making the set well suited for confined-space fastening tasks on the job site or in the shop.

This insert bit set is appropriate for residential and light commercial electrical, HVAC, and general mechanical work where multiple drive types are required in a single service call. Electricians, HVAC technicians, and plumbers will find the range of Phillips and square recess sizes especially useful for panel covers, junction boxes, access doors, and equipment enclosures. The slotted bits handle terminal screws and legacy fasteners commonly found in older residential and commercial installations.

Installation Notes

Insert bits should be seated fully and securely in the bit holder before applying torque to avoid cam-out or fastener damage. When working on electrical panels or equipment, de-energize and lock out the circuit per NFPA 70E safe work practices before using any hand or power tool. Inspect bits for wear or deformation before each use and replace damaged bits to maintain proper drive engagement.
