Screwdriver bit set Bosch 2607001459 — 3 pcs, extra hard, slot 4.5 mm, length 25 mm, 1/4" hex shank

Bosch extra hard screwdriver bit set with three slotted bits designed for general-purpose use. Each bit has a 4.5 mm tip diameter, 25 mm working length and a 1/4" hex shank for use in manual holders, power bit holders and three-jaw chucks. The bits are manufactured from S2 modified steel with an optimized heat treatment that gives extra-hard tips and improved wear resistance while the tapered torsion zone absorbs torque peaks.

Advantages

Extra-hard S2 modified steel and optimized heat treatment provide durable tips and consistent fit in slotted screws. The tapered torsion zone reduces the risk of breakage under torque peaks. The 1/4" hex shank ensures a secure connection and efficient torque transmission in compatible holders.

Suitable for

• Driving and removing slotted screws in wood, metal and plastic
• Use with manual screwdrivers that accept 1/4" bits
• Use with cordless drills, impact drivers and power bit holders with 1/4" hex chucks

How to use

Select the appropriate slotted bit and insert the 1/4" hex shank into a compatible screwdriver handle, bit holder or power tool chuck. Apply steady axial pressure while turning the tool to engage the screw slot. For power tools, use a moderate speed and controlled torque to avoid cam‑out or damage to the screw head. After use, store the bits in their blister packaging or a suitable bit organizer to protect the tips.

Usage recommendations

For best longevity, match the bit size precisely to the screw slot, avoid excessive side load, and replace bits that show visible wear or deformation. Use the tapered torsion zone to reduce stress during intermittent high torque applications.
