Product Overview
30xD Solid Carbide Drill —Engineered for Demanding Extra-Deep Titanium Alloy Hole Machining
The 30xD carbide drill for titanium alloy is designed for highly demanding extra-deep-hole applications where cutting heat control, chip adhesion reduction, pilot guidance, hole straightness, coolant delivery, tool rigidity, and process stability are critical.
Compared with 15xD or 20xD drilling, a 30xD titanium alloy application has a significantly longer unsupported drill body and chip evacuation path. It places much higher demands on pilot hole accuracy, spindle runout, tool holder condition, machine rigidity, coolant pressure and flow, flute consistency, and cutting parameter control.
Titanium alloys such as Ti-6Al-4V, TC4, Grade 5 titanium, and Grade 2 titanium have low thermal conductivity, high toughness, and a strong tendency to adhere to the cutting edge. Cutting heat remains concentrated near the drill point instead of transferring quickly into the workpiece or chips.
In a 30xD hole, titanium chips must travel through an extremely long flute path before leaving the cutting zone. Insufficient coolant delivery or unstable chip evacuation may cause chip packing, built-up edge, increased cutting torque, cutting edge overload, hole deviation, poor hole wall quality, or premature drill breakage.
This carbide drill is manufactured from imported MG grade 0.8 μm tungsten carbide rods with 10% cobalt content, supporting drill rigidity and cutting edge stability. Combined with HSR118 heat-resistant coating, reinforced flute geometry, internal coolant channels, controlled edge preparation, Walter inspection, and German Walter 5-axis grinding, it helps maintain reliable drilling performance and consistent hole quality in demanding extra-deep titanium alloy machining.
