Protects hole integrity
Lightweight design
Downline retention clips

Variety of sizes
UV stabilized material
The CollarCone is a tough plastic hole cone (hole saver) used to protect the collar and keep loose ground out. It’s designed for mines and quarries that want cleaner holes, steadier collars, and less re-drilling. The cone sits at the top of the hole, blocks drill cuttings, rocks, and water from falling back in, and keeps the opening clear while you work.
This hole cone is injection-moulded, not rotationally moulded. That makes it stronger, more consistent, and up to 20% lighter than other cones on the market . Each size stacks cleanly without sticking because of anti-lock tabs. Downline clips are built into the cone so your line stays put during loading.
Smaller sizes use a closed base for long-term hole retention. Larger cones (230 mm+) have an open bottom so you can load straight through the cone on the bench . All sizes are UV-stabilized, impact-resistant, and easy to see in MTi Green.
