The hexagonal shank ensures a secure fit in bit holders and power tools while the lightweight construction (31 g) makes it suitable for extended use.

Advantages

How to use

Insert the 1/4" hex shank into a compatible bit holder or powered screwdriver. Align the 3 mm tip with the fastener head and apply steady torque. When working at an angle, engage the ball end and maintain control; avoid excessive lateral force to prevent bit or fastener damage. After use, store the bit in a protective holder to preserve the lasered marking and finish.

Recommendations

Use the bit with compatible 1/4" hex chucks and avoid applying impact forces beyond the bit's rated use. For prolonged life, keep the bit clean and dry and replace when tip wear affects fit or torque transmission.
