This drill extension is made from 1/2" linear shaft with straightness tolerance of 0.002" and C60 Rockwell hardness. The linear shaft is mated to a 1/2" coupler that will accepts 1/2" shanked bits and 7/16" hex shanked bits. Other types of shanks can also be used in the drill extension with the adapter bushings we sell. These include bits that have 3/8" shanks, 5/16" hex shanks, and 1/4" hex shanks.
Please contact us if you would like drill extension in a size not listed here.
Note - All Drill Extensions come with a flat machined on one end of the shaft. This flat is for the set-screw of the 1/2 coupler we provide with our drill extensions.
FYI - Estimated shipping costs are based on the 18" Drill Extension. Due to the variation in sizes and shipping costs, we will refund any shipping overages when the order ships, and if it is combined with other items.
