Description
The Sthor bit set 31-piece (product number 66302) is a comprehensive, multi-purpose selection of screwdriver bits designed to make screwdriving more efficient in various installation and maintenance jobs. The set contains 30 screwdriver bits 25 mm long and one magnetic bit holder, all packed in a durable, compact plastic case with a clearly marked place for every part. This ensures the set stays in order and makes it quick to find the right bit in the middle of a job.
All the bits in the set are made of high-quality CrV steel (chrome vanadium steel), which gives them excellent durability, torque resistance and a long service life even in demanding screwdriving applications. CrV steel is known for its toughness, which reduces the risk of bits breaking under heavy load. The bits are precision machined to ensure an optimal fit in the screw head, which reduces slipping (cam-out) and protects both the bit and the screw head from damage.
The versatility of the set comes from its wide selection of bits, which covers most commonly used screw head types and sizes. It includes slotted bits (Flat), Phillips bits (PH), Pozidriv bits (PZ)

Sthor bit set 31-piece instructions for use:
Choose the bit that fits the screw head exactly to avoid damage. Push the bit into the magnetic bit holder until it locks. Fit the bit holder in a screwdriver or drill. Press the bit firmly against the screw head while driving. Use a suitable torque; do not overload small bits. Keep the bits clean of dirt and oil. Always store the set in its own case when not in use, so that parts do not get lost and stay protected.
Warnings:
- Always wear safety glasses when power screwdriving.
- Make sure the bit sits firmly in the screw head before starting the machine.
- Do not use damaged or worn bits.
- Do not exceed the recommended maximum torque of the bit or screw.
- Keep out of the reach of children.
- Use only with machines whose speed can be adjusted.
