Specification: This is a new adjustable aluminum drill stand that is perfect for shops or homes. This plug-in rig is ideal for keeping the drill bit stable during use and more precise than handheld operation. (The specific deviation, with the concentricity of the used electric drill, as well as personal operation technology, have a great relationship.) The electric drill has high concentricity and small vibration, which can reduce the deviation. With a drilling depth of up to 60 mm, it has a sturdy post and a sturdy base with slots for the machine vise. Working parameters Main： shaft : 400mm Clamping : 38-42mm Single stroke : 0-60mm Base material: aluminum alloy Weight : 1.5KG.
