Designed for stable short-hole drilling in titanium alloys and difficult-to-machine materials, this 3xD carbide drill combines imported submicron carbide, heat-resistant coating, optimized point geometry, and controlled edge preparation to improve cutting stability, reduce chip adhesion, and maintain reliable hole quality in high-temperature drilling conditions.
The 3xD carbide drill for titanium alloy is developed for short-hole drilling applications where cutting heat, chip adhesion, and tool wear are major challenges. Titanium alloys have low thermal conductivity and high material toughness, which can cause heat to concentrate around the cutting edge during drilling. This makes tool geometry, coating performance, and edge stability especially important.
Manufactured from imported MG grade 0.8 μm submicron tungsten carbide rods with 10% cobalt content, this drill provides the toughness and rigidity required for high-speed machining of titanium alloys. Its optimized point geometry helps improve entry stability and reduce drill walking, while the flute structure supports smoother chip evacuation and more stable cutting performance.
With self-developed high-performance coating, controlled edge passivation, and internal or external coolant options, this drill is suitable for customers who need reliable hole accuracy, improved chip control, and longer tool life in titanium alloy drilling.

Production Facility
Geometry Accuracy Control
Edge Inspection Magnification
Edge Passivation Control
Our carbide drills are ground on German WALTER 5-axis grinding machines for sharp cutting edges, stable accuracy, and smooth drilling performance.
We use WALTER HELICHECK PLUS for contour inspection, keeping profile and radius control within 3 μm for reliable geometric precision.
Each carbide drill is inspected at 300x magnification to check edge quality and avoid chipping or saw-tooth defects before shipment.
Manual drill point honing and automatic rubber-bonded diamond abrasive polishing help improve tool life and control edge consistency within ±0.003 mm.
Common Questions
3xD means the drill is designed for hole depths up to 3 times the drill diameter.
Yes. This drill is designed for titanium alloy drilling, helping improve heat resistance, reduce chip adhesion, and maintain stable hole quality under suitable machining conditions.
It is suitable for titanium alloy, Ti-6Al-4V, TC4, Grade 5 titanium, Grade 2 titanium, and other difficult-to-machine alloy materials under suitable drilling conditions.
Titanium alloys have low thermal conductivity, high toughness, and strong chip adhesion tendency. A suitable carbide drill requires heat-resistant coating, stable edge strength, and optimized chip evacuation to maintain drilling performance.
Internal coolant is recommended when better heat control and chip evacuation are required. External coolant versions are also available depending on machine conditions and hole requirements.
Yes. We support customization based on drawings, titanium grade, hole depth, coolant method, coating requirement, and drilling application.
