Question: What is the red 'unlock' handle for, and is it removable or movable or what?
Document: The red handle could be helpful if they let you adjust it in two directions but unfortunately, it only goes in one giving you very little leverage where you need it.
It is also rated at a much higher torque. The funny looking red bar in the photo is a multi-position handle that locks into position and gives you the much needed leverage in tight spaces.You may not use this tool every day, but when you need a right angle driver/drill man, you need this.
You can tell from the weight of this tool in your hand it is well built. The weight is nice for control without feeling heavy.The red handle on it can be rotated around the shaft for tight places and the angle to the shaft can also be adjusted with ease. To adjust these, unscrew the red handle a little and then push the red handle all the way forward to rotate it. After you have it rotated to the position you like, you can change the angle and tight it back up.
The handle fell off after a few weeks of light usage. For this price, it should be a much tougher product.
very handy tool for those tight areas, very durable and easy to use. I like the handle on the tool makes it easy to hold on to.
This right handle drill attachment is very useful and very solid: I used it for 2 year with my impact wrench (not recommended) and it did not break.
Really solid bit of kit and gets into the tight corners. Good handle to apply pressure and is adjustable. Very useful accessory.
very handy tool. you will need this for space limited applications or where a stubby tool is needed. comes with a good adjustable handle. solid product and it attaches to normal drill.
Try performing that task with gloves on.The adjustable handle is similarly annoying with its ill-conceived and time-consuming locking mechanism. Want to move it to a new position?
This handle makes all the difference in keeping the attachment stable and just where you want it. It adjusts easily up/down/left/right---pretty much any angle or position around the head of the attachment.
Answer: yes
