The internally cooled tool 2 includes a blade portion 210 and a shank portion 220 connected to the blade portion 210. Unlike metal chips formed by metal machining, the chips formed by drilling quartz products are in powder form. Therefore, the shank portion 220 is a straight rod with a smooth outer surface. The outer diameter of the blade portion 210 is larger than the outer diameter of the shank portion 220. A coolant inlet channel 221 is provided inside the shank portion 220, and a coolant outlet 211 is provided on the blade portion 210.

[0037] See also Figure 4The internally cooled rotary adapter for deep hole machining of quartz products disclosed in this embodiment is used in combination with an internally cooled tool. When deep hole machining of quartz products, coolant flowing from the coolant inlet into the internally cooled rotary adapter passes through the coolant outlet and inlet channels before flowing out of the coolant outlet on the cutting edge of the internally cooled tool, continuously flushing the cutting edge. This not only cools the cutting edge but also removes quartz powder formed during drilling. The flushed coolant, containing the quartz powder, flows outward from the gap between the tool shank and the hole wall.
