A set of 10 long hexagonal bits, essential for a wide range of fastening tasks, from DIY to professional maintenance sites.
To address situations where standard bits cannot reach, such as screws located in recessed areas or narrow gaps, a long design with a total length of 100mm has been adopted.
Designed for use with impact drivers and electric drills, it is equipped with a highly versatile 1/4 inch (6.35mm) hexagonal shank.
It demonstrates its capabilities in all situations where hex socket bolts are used, including furniture assembly, bicycle and motorcycle maintenance, and machinery inspections.

For the bit material, S2 alloy steel, highly reliable for industrial tools, has been carefully selected.
Through appropriate heat treatment, it maintains high hardness while possessing moderate toughness (resilience), physically suppressing tip chipping and breakage even under impact or strong tightening torque.
The surface is sandblasted to reduce friction and prevent rust due to moisture.
It features a robust construction that maintains its functionality even during long-term use in harsh working environments.

This product employs a high-precision concentric shaft design that minimizes shaft runout to the extreme.
Even at high rotation speeds, the bit tip stably engages with the screw head, preventing dislodgement due to centrifugal force.
The precise engagement with the screw head prevents damage to the screw hole due to cam-out, enabling torque transmission.
It reduces stress for the operator and supports efficient work in situations requiring precise tasks.
The length ensures visibility even when working in recessed areas, allowing for accurate tightening of the target location.

A powerful magnet function is built into the tip.
By attracting and holding steel bolts and screws, it significantly improves work efficiency in locations where one-handed operation is difficult or in narrow spaces where screws are easily dropped.
Simply by changing the bit, tasks that would take time with a manual wrench can be completed speedily.
A dedicated holder is included for organizing bits by size, preventing them from scattering in the toolbox and allowing for quick identification of the desired size.

It systematically covers 10 major sizes from 1.5mm to 10mm, allowing this single set to handle a wide variety of bolt diameters.
The configuration meets a wide range of needs, from simple home repairs to professional vehicle maintenance and installation of home equipment.
It is designed as a practical set of basic tools that you will want to keep at hand at all times.
It is ideal not only for replacing worn-out bits but also as a starter set when introducing new power tools.
Please experience the smooth operability with this bit set.
