Screwdriver bit set KS Tools 911.7550 — 32 pcs, nickel, 75 mm, 1/4" (25.4/4 mm) hex shank

KS Tools 911.7550 is a 32-piece screwdriver bit set with a nickel finish, each bit measuring 75 mm in length and fitted with a 1/4" (25.4/4 mm) hexagonal shank. Manufactured to DIN 3126 and ISO 1173 (E 6,3) standards, the set is compatible with standard bit holders, bit sockets and most power drivers. The selection covers commonly used slotted, Phillips, Pozidriv, Torx and hex profiles, providing a practical range for workshop use and on-site repair tasks.

Advantages

The bits are nickel-plated for corrosion resistance and easier handling, while the standard-compliant hex shank ensures secure fit in 1/4" holders and powered drivers. The 75 mm length gives better reach into recessed fasteners and improved access in confined spaces. The 32-piece assortment reduces the need to search for individual bits and supports efficient task flow in maintenance and assembly work.

Suitable for

• General workshop maintenance and repair
• Automotive and motorcycle service tasks
• Furniture assembly and joinery that require extended reach

How to use

Select the bit matching the screw head profile and insert it into a compatible 1/4" bit holder, adapter or power driver. Ensure the bit seats fully in the holder before applying torque. For manual work, use with a bit holder or screwdriver handle; for powered fastening, ensure the driver speed and torque settings are appropriate for the fastener and material to avoid cam-out or damage. After use, clean bits of debris and store them in the original case to keep the set organized and protected.

Usage recommendations

Use the correct profile and size bit for each fastener to reduce wear and avoid rounding. For high-torque applications choose impact-rated bits or use a suitable socket/adapter and lower speed settings on your power tool. Store bits dry and wipe off any grease or dirt before returning them to the case to prolong the nickel finish and maintain fit accuracy.
