Designed for precision micro-hole drilling in titanium alloys and difficult-to-machine materials, these 3xD micro carbide drills are manufactured from imported MG grade 0.8 μm tungsten carbide with 10% cobalt content, combined with HSR118 heat-resistant coating, controlled edge passivation, and high-precision grinding to improve heat resistance, reduce chip adhesion, and maintain stable hole accuracy in small-diameter titanium alloy machining.
The 3xD micro carbide drills for titanium alloy are designed for small-diameter hole machining where heat control, edge strength, hole positioning, and tool breakage resistance are critical. Compared with standard carbide drills, micro drills are more sensitive to cutting heat, spindle runout, chip adhesion, and cutting edge consistency.
Titanium alloys such as Ti-6Al-4V, TC4, and Grade 5 titanium have low thermal conductivity, high toughness, and strong adhesion tendency during machining. In micro-hole drilling, cutting heat is concentrated around the small cutting edge, while chip adhesion and tool overload can quickly lead to burrs, hole deviation, poor surface quality, or premature drill breakage.
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 stability. 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 resistance, reduce chip sticking, and maintain reliable micro-hole accuracy in titanium alloy components.

Key Features
Made from imported MG grade 0.8 μm tungsten carbide with 10% cobalt content.
The fine carbide grain structure helps support edge strength, rigidity, and stable micro-hole drilling in tough titanium alloy materials.
HSR118 coating is designed for titanium alloy machining where heat and adhesion are major challenges.
It helps reduce chip sticking, protect the cutting edge, and improve stability under high-temperature micro-drilling conditions.
The drill point is manually honed and chamfer-passivated to improve cutting edge strength.
Automatic rubber-bonded diamond abrasive polishing keeps edge consistency and controls the passivation value within ±0.003 mm.
Produced on German Walter 5-axis high-precision grinding machines to ensure sharp and accurate cutting edges.
Walter Helicheck Plus inspection and 300x magnification checks help control geometry accuracy and prevent edge defects.
These 3xD micro carbide drills for titanium alloy are suitable for precision small-hole machining in CNC machining centers, high-speed drilling equipment, and production environments where heat control, hole accuracy, edge consistency, and tool reliability are important.

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. For micro drills, this depth is suitable for stable small-hole machining with better rigidity and positioning control.
Yes. These 3xD micro carbide drills are designed for titanium alloy materials, including Ti-6Al-4V, TC4, Grade 5 titanium, Grade 2 titanium, and other difficult-to-machine alloys under suitable machining conditions.
This micro carbide drill uses HSR118 heat-resistant coating, which helps improve heat resistance, reduce chip adhesion, and protect the cutting edge during titanium alloy micro-hole drilling.
Titanium alloys have low thermal conductivity, high toughness, and strong adhesion tendency. In micro-hole drilling, cutting heat and chip sticking can quickly affect hole accuracy, edge stability, and tool life.
Micro drills have very small cutting edges and are sensitive to chipping or uneven edge conditions. Controlled passivation helps strengthen the cutting edge, improve consistency, and reduce premature drill breakage.
Yes. Proper coolant support helps control cutting heat, reduce chip adhesion, and protect the cutting edge. The coolant method should be selected according to hole diameter, depth, machine condition, and titanium grade.
We use German Walter Helicheck Plus for contour measurement, with profile and radius control within 3 μm. The products are also inspected at 300x magnification to check edge appearance and avoid chipping or saw-tooth defects.
Yes. We support customization based on diameter, hole depth, shank size, coating, stainless steel grade, drawings, samples, and machining requirements.
