Most directional boring machines use drilling fluid while a few machines are designed to use either air or air and foam. Air & foam machines are used for drilling in rock. Directional drilling fluid is generally a mixture of bentonite clay and water, with additives used to improve borehole performance. In softer soils the jet of fluid cuts

Boring bars are a simple plug-and-play solution and are offered here in the minimum bore depth range of 0.0175 inch to 1-1/2 inches or 1 mm to 12 mm and maximum 

Boring Bars Use a Steel Boring Bar if you are reaching less than 4X Length to Diameter. Use a Carbide Boring Bar is you are reaching between 4X to 8X Length to Diameter or if finish is

Carbide Boring Bar Brazed It does have a cutting speed of 2.5 to 5 times that of HSS. This lathe boring technique implies it can withstand a lot of heat. Metal has a stiffness factor of 2.5 times that of brazed carbide. However, as the sharp edges of this form of boring lathe wear out, it must be reprocessed (that is very hard) or destroyed.

Carboloy S16-PTFPR-2.5 boring bar with 1" shank. The shank has been cut short, giving a new over-all length of around 8.25". Part of the boring bar has been ground away to give more clearance. The bar looks to be in good working condition.
