2pcs 1/4 inch Metal Screwdriver Bit Magnetic Rings for 6.35mm Shank Anti-Corrosion Drill Bit Magnetizer Screws Magnet Powerful Ring Blue Specification: Material: Metal Aperture: 1/4 inch Function: With the grooved bit, it is more convenient to absorb/fix and install the screws. The abrasion of the bit is mainly due to the fact that the bit cannot be completely matched with the screw during the screwing process, which leads to the damage of the bit. The magnetic ring can firmly attract the screw to prevent the bit from slipping, thereby prolonging the service life of the bit. Instructions: 1. Insert the magnetic steel sleeve into the 6.35mm bit for connection; 2. Confirm that the magnetic steel sleeve has been fixed on the bit; 3. Put the screw on the bit with the magnetic steel sleeve inserted; 4. Prevent the screws from falling off. Note: Only 2pcs batch head magnetic ring, no other accessories. Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-3cm measuring deviation due to manual measurement. Included: 2 X Batch Head Magnetic Ring
