• Good metal structure, comfortable sheath surface, easy to tighten to increase the output torque.
• The unique axial bearing makes it easier to put torque through the handle for greater clamping force.
• Beautiful and practical design of convex and concave surface, so that the shaking of the jacket can be dealt with and reduced effectively.
• Widely used with different drilling machines, milling machines, lathes, drilling machines and electric hand tools.
• The shank hole is a taper hole, drill chuck the average precision is higher. Professional connection tool with chuck, hammer drill bit, with firmer connection performance.

	Beautiful and practical design of convex and concave surface, so that before and after the kit, can be effectively dealt with the shaken and reduced coat
