Drill Bit Wera 05058112001 2.5 mm Diameter 30 mm Length 1 pc

Bits for hexagonal socket screws with Hex‑Plus geometry provide larger contact surfaces in the screw head, reducing the notch effect and minimizing damage to the screw. This Wera drill bit is a tough, universal bit with a 4 mm hexagonal drive, intended for precise work where a 2.5 mm drill diameter and 30 mm length are required.

Advantages

The Hex‑Plus design increases contact area in the screw recess, lowering the risk of cam‑out and preserving the integrity of the screw head. Made for universal use, the bit combines durability with precision suitable for repeatable, accurate operations. Supplied as a single piece, it is compact and easy to store or carry in a bit holder.

Suitable for

• Precision drilling and screwdriving tasks in electronics and small mechanical assemblies
• Maintenance and repair work requiring accurate 2.5 mm bits
• Use with bit holders and compact screwdrivers that accept a 4 mm hex drive

How to use

Insert the bit into a compatible 4 mm hex bit holder or screwdriver chuck. Select appropriate speed and torque for the material being worked on to avoid oversizing the hole or damaging the bit. Apply steady, aligned pressure while drilling or driving screws; withdraw periodically when drilling deeper holes to clear debris and maintain cutting performance.

Recommendations

For best results, use the bit at moderate speeds with controlled torque and keep it clean of chips. Replace the bit if wear or rounding of the tip is observed to maintain precision and prevent damage to screw heads.
