SYSTEM
Coolant is pushed in around the tube and carries the chips back out through it. Because the chips stay off the finished wall, the hole keeps its straightness and finish, even deep down.
Part of the coolant fed between the two tubes is jetted backwards, creating suction that draws the chips out. No sealed pressure head is needed, so deep holes can be drilled on conventional lathes and machining centres.
BTA DRILLING LINE-UP
Below Ø25 mm choose the GHD; above Ø65 mm, the LHD or THD. The 500 series sets its diameter with cartridges.
Tell us the workpiece material, hole diameter, depth and machine, and we will suggest the right tool.
