Drilling Titanium Best Left to Experts

from Titanium By Matthew J. Donachie »

Successful drilling of titanium and titanium alloys requires the use of low surface speeds, heavy cuts (with controlled down feed if available) sharp tools of the correct geometry, rigid setups, and liberal amounts of coolant.

These procedures reduce the amount of heat generated during cutting operations, thereby providing protection against dulling of the drill and galling and smearing on the cutting faces and margins.

The major factors in successful titanium drilling are chip flow, clogging, and point smearing. These factors are determined by the depth of the hole drilled, which, in turn, determine drill life.

Successful drilling can be accomplished with ordinary high-speed steel drills. One of the most important factors in drilling titanium is the length of the unsupported section of the drill. This portion of the drill should be no longer than necessary to drill the required depth, yet still allow the chips to flow unhampered through the flutes and out of the hole. This permits application of maximum cutting pressure, as well as rapid removal and re-engagement to clear chips, without drill breakage.
