기능

• A set of 6 pieces carefully selected in the sizes often used for drilling in the field.
• Pack-zip wrapping to protect the drill from loss and dirt. The opening of the bag can be sealed and stored.
• X-shaped thinning cutting edge. Easy to eat, no need for center punch.
• High hardness HHS high steel. Sharp sharpness lasts.
• The drill and bit shaft are integrated by press drawing. It doesn't come off and go around like glue.
• Cushion ring effect to reduce touch and rattling. The cushion ring in the chuck of the electric screwdriver prevents the bit from rattling and eliminates the wobble.
• Cushion rings are colored by size. The required size is easy to find visually.
