[✦ Recommended Points & Features]
●Reliable Japanese Brand Design
Designed and manufactured by the long-established tool maker Kyoto Tool (KTC). It has a strong track record and reliability in domestic automotive maintenance environments.
●Compatible with 3/8″ Drive / Highly Versatile Standard
Supports the widely used 3/8″ (9.5 mm) drive found in automotive socket wrenches. It can be combined with many ratchets and sockets, naturally fitting into your existing tool lineup.
●Optimal Length (150 mm) for Usability
The 150 mm length strikes a good balance between access in tight spaces and operability. Ideal for areas where a socket alone is hard to reach or when turning nuts and bolts while avoiding obstacles.
●Swing Type (Angle Movable) Design
The “BE3-150JW” variant features a 13° swing angle, allowing “back-and-forth” operation even in confined spaces where full rotation is difficult.
This mechanism reduces the need for repeated position adjustments each time the socket is replaced.
●“Power-Fit Shape” Reduces Stress Concentration
The joint with the socket incorporates a “Power-Fit Shape” designed to prevent stress from concentrating in a single point, reducing the risk of breakage under load.
●Consideration for Dimensional Accuracy and Play Suppression
The drive section is manufactured with tight tolerances to minimize wobbling with the socket. This design reduces subtle play during operation, providing a firm and responsive feel.
●Durable Special Tool Steel Construction
The BE3-150 uses highly durable materials such as “special tool steel,” capable of withstanding repeated loads and impacts.
●Thoughtful Shape and Usability
The shaft is slimmed at the center, improving manual handling when turning by hand (without the ratchet).
The length also helps reach bolts and nuts that are difficult to access.
[Summary]
The KTC BE3-150 Extension Bar combines the classic 3/8″ drive standard with high dimensional accuracy, stress-dispersing design, and a swing mechanism, offering both usability and reliability for maintenance work.
It is ideal for those seeking accessibility in tight spaces, a secure operational feel, and durability. Pairing it with a socket set will surely improve your daily maintenance efficiency.
