Designed for stable medium-depth drilling in titanium alloys and difficult-to-machine materials, this 5xD carbide drill combines imported submicron carbide, HSR118 heat-resistant coating, optimized point geometry, and reinforced flute structure to control cutting heat, reduce chip adhesion, improve chip evacuation, and maintain reliable hole quality in titanium alloy drilling.
The 5xD carbide drill for titanium alloy is developed for medium-depth hole machining where cutting heat, chip adhesion, tool wear, and chip evacuation are major challenges. Compared with 3xD short-hole drilling, 5xD titanium alloy drilling requires better heat control, stronger edge stability, and smoother chip removal over a longer drilling depth.
Titanium alloys such as Ti-6Al-4V, TC4, and Grade 5 titanium have low thermal conductivity and high material toughness. During drilling, heat is concentrated around the cutting edge, while chips are more likely to adhere to the tool surface. Without a suitable drill geometry and coating, this can lead to built-up edge, rapid tool wear, unstable hole quality, and poor machining efficiency.
This 5xD carbide drill is manufactured from imported MG grade 0.8 μm submicron tungsten carbide rods with 10% cobalt content. Combined with HSR118 heat-resistant coating, optimized point geometry, reinforced flute structure, and controlled edge preparation, it helps improve cutting stability, reduce chip adhesion, and support reliable medium-depth drilling in titanium alloy components.

Key Features
Made from imported 0.8 μm submicron carbide with 10% cobalt for toughness and rigidity.
Helps maintain edge stability during medium-depth drilling in titanium alloys and high-temperature materials.
HSR118 coating is designed for titanium alloy machining where heat and adhesion are major challenges.
It helps improve heat resistance, reduce chip adhesion, and slow down tool wear during drilling.
30° helix and 138.9° point angle support stable penetration and accurate hole positioning.
Split-point design helps reduce drill walking and improves entry stability in tough titanium materials.
16° rake angle and variable core design improve rigidity and chip evacuation in 5xD drilling.
Negative chamfer and back taper help protect the edge, control chips, and maintain stable hole quality.
This 5xD carbide drill for titanium alloy is suitable for medium-depth hole machining in CNC machining centers and precision drilling applications. It is especially useful for titanium alloy components where cutting heat, chip adhesion, chip evacuation, hole straightness, and tool wear must be controlled.
