The helix design of our glass grinder bits is engineered to efficiently draw water up to the grinding surface, eliminating the need for a sponge. However, if you prefer to use a sponge, you can do so, ensuring a consistent water supply to the bit. This feature helps maintain the proper lubrication and cooling required during the grinding process.

It's important to note that all our helix glass grinder bits are electroplated in-house at our factory. This means that we handle the electroplating of our own diamond products, allowing us to offer the highest quality grinder bits at more competitive prices than any other source. This control over the manufacturing process ensures that you receive top-notch grinder bits that deliver excellent performance and durability, all at a cost-effective value.
