Gun Drilling For Precision Machining

At CDM Tool & Manufacturing, we keep a range of specialty machining processes in our toolbox to tackle any mold making or machining job. Through gun drilling, deep holes can be drilled in a workpiece with extreme precision.

Using fluted drills with coolant pumped through, we can bore holes with an extremely high depth-to-width ratio. Our equipment and skilled machinists give us the edge in any job which requires gun drilling to complete. Contact us to get access to our gun drilling capabilities on your project.

Frequently Asked Questions

What is gun drilling in machining?

Gundrilling, also called precision hole drilling, is a machining technique for drilling holes in a workpiece beyond the capability of conventional drills. Gun drill machining can produce deep holes in a workpiece with extreme precision.

What is the gun drilling process?

Gun drilling involves taking a gun drill bit with a small hold in the center to perform deep cuts. During the cutting process, high-pressure oil is injected through the center hole to force the escape of the excess material. The drill bit has a portion of its diameter removed for further evacuation of excess material.
