Axminster Super Precision Keyed Chuck

It is often the case that an otherwise good quality power drill is fitted with a poor quality, low cost chuck. With a guaranteed run out of less than 0.075mm these precision chucks are very well made and actually close down to nothing (especially useful if you have no holes to drill!). Made of high grade SAE1045 tool steel ground and hardened to HRC52, these chucks are more suited to the rigors of engineering applications than to power tool use. They are drilled and countersunk to accept left hand screws for security when drilling in reverse. 0-13mm capacity.
