2mm Coolant-Thru Drills for Titanium with Bright Gold Coating
29 Apr 20262mm · Coolant-thru · Titanium · Gold coating · Custom drill
This case shows a batch of 2mm solid carbide coolant-thru drills made for titanium machining. At this diameter, titanium drilling is sensitive to heat, chip packing, and runout, so the drill must work as a complete system: substrate, point geometry, flute finish, internal coolant, and coating.

Internal coolant for titanium
Coolant channels help flush chips from a very small 2mm hole and reduce heat concentration at the cutting edge.
Bright gold PVD coating
The coating is selected to reduce adhesion, improve heat resistance, and protect the micro cutting edge in titanium.
Micro-drill geometry control
Point geometry, edge consistency, flute polish, and runout are inspected closely because small errors shorten tool life quickly at 2mm diameter.
Factory-direct customization
Geometry, coating, flute length, coolant-hole design, and inspection requirements can be adjusted around the customer drawing and machine conditions.
For a similar 2mm titanium drilling tool, send hole depth, tolerance, titanium grade, coolant pressure, holder type, machine spindle runout, target quantity, and current failure mode. We will review the geometry and coating route before quoting.
