Micro Deep-Hole Drills for Small Diameter Deep-Hole Drills

Getting deep holes right, efficiently, requires more than just a good tool. Shops need to have a complete, accurate machining process and implement operating procedures that ensure tolerances, repeatability and surface finish. This is especially true when the machining operation involves long, thin drills with a narrow point angle.

For such applications, a wide range of manufacturing processes exist. Some, like gun drilling, are limited to holes with diameters only 10 times greater than the depth of cut, while others, such as spade drills and high-feed twist drills, provide only limited deep-hole capabilities without special equipment.

However, a new generation of micro deep-hole carbide drills can meet many prototyping and production requirements with diameters of 20 to 80xD and cutting materials from common to exotic materials. In addition, they use a unique flute geometry that allows for optimal chip evacuation even from very deep holes. The geometry also ensures the correct supply of coolant to the cutting edge. Combined with the correct cutting settings, this combination provides clean cuts and extends the tool’s life. It also eliminates the need for re-starting and interrupting the cutting sequence to peck holes.
