The Metro Drill Arbor is a Morse taper arbor used to mount and hold drill chucks securely on machine spindles, keeping the chuck running straight and true during operation. Its outer diameter is fully grinded and precisely maintained, ensuring the arbor seats accurately into the machine spindle while holding the drill chuck without wobble or misalignment.

Straight, consistent holding is essential for drilling accuracy — any looseness or runout in the arbor-to-chuck connection translates directly into inaccurate holes, increased bit wear and vibration during use. The Metro Drill Arbor's precision grinding addresses this at the source, giving machinists and fabricators a reliable connection between spindle and chuck.

Available in MT2 and MT3 taper sizes, with the MT3 range offered in two chuck-mount diameters (1/2" and 3/4"), this arbor range covers common drill press and machine tool configurations. Sold individually or in standard and carton pack quantities, it's a practical stocking item for workshops and machine shops running multiple drill press or lathe setups.
