Product Overview
5xD Micro Carbide Drill —Engineered for Medium-Depth Titanium Alloy Micro-Hole Drilling
The 5xD micro carbide drills for titanium alloy are designed for small-diameter hole machining where heat control, chip evacuation, tool rigidity, and edge stability are more demanding than 3xD micro drilling. In 5xD titanium alloy micro-hole applications, the drill must maintain stable cutting performance over a longer depth while reducing chip adhesion, cutting heat buildup, hole deviation, and premature drill breakage.
Titanium alloys such as Ti-6Al-4V, TC4, and Grade 5 titanium have low thermal conductivity, high toughness, and strong adhesion tendency during machining. During medium-depth micro-hole drilling, cutting heat is concentrated around the small cutting edge, while chips are more difficult to evacuate because of the longer drilling path and limited flute space.
These micro carbide drills are manufactured from imported MG grade 0.8 μm tungsten carbide rods with 10% cobalt content, supporting high-speed cutting and small-diameter drilling strength. With HSR118 heat-resistant coating, manual drill point honing, automatic edge passivation, Walter Helicheck Plus inspection, and German Walter 5-axis grinding, the drills help improve heat control, reduce chip sticking, protect the cutting edge, and maintain reliable micro-hole accuracy in titanium alloy components.
