Why Choose from us?
This drill bit contains 5% Cobalt (M35 Cobalt HSS), which increases the strength, the tool life and makes it more heat-resistant.
Rockwell Hardness >= 67.
135° Split Point with straight shank prevents walking and makes drilling precise.
Fully Ground spiral groove design clears particles quickly, decreases friction and heat for a faster and cooler drilling performance.
Drilling Notice:
Keep the drill bits vertical to the object when drilling. Be sure to make both bit and work piece stable.
Tilted bit is prone to break. When using bits with a power drill, it's recommended to use them with low speed and drilling pressure. The thicker the bits is, the slower speed and pressure should be taken.
Friction will accumulate heat between bits and work piece. Be aware of the heat, add water or coolant if necessary.
To avoid breaking, 1/16" and smaller bits are suggested to be used with a pin vise. Thick metals are recommended to be drilled with drill press, which is more stable, and adjustable.
To have the best performance, you shouldn't drill deeper than 1/2" of the drill bits' flute length.

Common questions about buying open-box and refurbished.
Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $7 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for VALYRIANTOOL products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
