Deep Hole Drilling

Deep Hole Drilling (Gun Drilling) Services

Specialized in high-precision deep hole drilling for mold bases, cavities, and cores. Our gun drilling technology ensures straight, deep holes with excellent surface finish, critical for water line channels, ejector pins, and hot runner systems.

Mold Cooling & Venting Solutions

Efficiently drill deep water circulation holes to optimize mold cooling cycles and prevent product defects. We also handle complex angles and intersecting holes, ensuring the integrity of the mold structure while meeting thermal management requirements.

Tight Tolerances & Straightness

Capable of drilling depth-to-diameter ratios exceeding 20:1 with minimal deviation. Our process maintains tight tolerances on hole diameter and straightness, reducing the need for secondary reaming and ensuring a perfect fit for tubing and pins.

Material Expertise

Experienced in drilling through hard mold steels (P20, H13, S136, etc.) with controlled chip evacuation and coolant delivery. This minimizes tool wear and heat-affected zones, preserving the hardness and durability of the mold.

Integration with Mold Making

Deep hole drilling is seamlessly integrated into our CNC and EDM workflows. Pre-drilled holes are verified by CMM before assembly, ensuring that cooling and ejection systems function flawlessly during the mold trial stage.
