Key Features & Benefits

• Monoblock solid carbide body: high rigidity that suppresses torsion and vibration, delivering tighter diameter and position accuracy—especially in small bores.
• Hole wall quality: with the right Nose grinding geometry plus coolant & chip-evacuation, it achieves stable straightness and smooth surface finish.
• Depth capability: supports ≤100xD deep-hole requirements depending on series and setup.
• Productivity: under proper conditions, peck cycles can be omitted to boost speed and stability.
• Typical applications: medical (stainless/titanium), semiconductor parts & fixtures, mold cooling channels, micro-flow passages, etc.

Comparison vs. Brazed-Tip Gun Drills

• Precision & rigidity: solid carbide offers advantages in small-diameter, high-precision holes and productivity; brazed-tip suits large diameters, extreme L/D, wider size coverage and cost flexibility.
• Cost: solid carbide has a higher unit price but benefits from multiple regrinds; brazed-tip usually has lower initial cost.
• Large bores / extreme L/D: consider brazed-tip or insert-type designs for better economics or maintainability in specific cases.
