Draper Screwdriver and Bit Set - 23 Piece

Cross Slot (Phillips) bits have four points of contact and are designed for a specific type of screw head. PZ TYPE bits are an enhanced design with additional contact points, providing better grip and torque transfer on Pozidriv and Supadriv screws, reducing cam-out.

While the bits are 1/4" hexagon and can physically fit into a drill's chuck or a drill bit holder, the 25mm length and lack of a dedicated shank for power tools make them best suited for manual screwdrivers. Excessive speed or torque from a power drill could damage the bits or the screws.

This refers to a heat treatment process that makes the steel bits harder and more resistant to wear, while also increasing their toughness to prevent brittleness and breakage under stress.

Wipe them clean with a dry cloth after use and store them in a dry place. Avoid using solvents or lubricants, as they can attract dirt and may degrade the magnetic holder over time.

The included adaptor converts the screwdriver's 1/4" magnetic hexagon holder to a 1/4" square drive. This allows you to potentially use compatible socket wrenches or other tools that utilize a 1/4" square drive interface.

Yes, the bits are standard 1/4" hexagon drive bits. You can purchase replacements individually or in sets from hardware stores, matching the type and size needed.

Ensure the bit is fully inserted into the holder. Check the magnet for any debris that might be hindering its grip. If the magnet appears weak, the bit may be damaged or the holder compromised.

Confirm you are using the correct bit type (e.g., PZ TYPE vs. Cross Slot) and size for the screw. Ensure the bit is fully seated in the screw head before applying torque.

This may indicate excessive force is being applied or the wrong bit type is in use. Reduce torque or switch to a more appropriate bit. Hardened alloy steel bits are durable, but improper use can still cause damage.
