Description
★ Drill Bit Size --- Cutting edge diameter: 12.5mm; shank diameter: 12.5mm; cutting edge length: 100mm / 3.94"; overall length: 150mm / 5.91", Included: 5 Pieces x Drill Bit
★PRACTICAL PERFORMANCE --- The metric twist drills offers excellent toughness, combining a black and gold finish and a 118° angle design. It has significant advantages in processing performance and cost-effectiveness, achieving superior processing at low cost and striking a perfect balance between cost and quality.
★ Wide Applications --- For acrylic, plastic, wood, soft metals (Cu, Al alloys), carbon steel, cast iron & thin stainless steel, suitable for vehicle maintenance like sheet metal, bolt holes, brackets, wire harness mounts. (not to be used on hardened steels, high-alloy steels, thick stainless steel, or other ultra-hard materials.)
★ 4341 High-Speed Steel (HSS) --- Offers high hardness, excellent wear resistance, and good toughness. It is a versatile drill bit suitable for machining medium- to low-hardness materials.
★ Useful Tips --- Ensure the drill bit is perpendicular to the workpiece surface—tilting can cause breakage or hole deviation. For beginners: Always verify proper speed and feed rates before formal workpiece machining.

Applications & Features:
---Applicable materials: Acrylic, plastic, and wood. soft metals such as copper, aluminum alloys, carbon steel, cast iron, and stainless steel thin plates (use with caution for thick plates)
---Applications: The 4341 High-Speed Steel (HSS) Twist Drill is a versatile drill bit suitable for machining medium- to low-hardness materials, commonly used in vehicle maintenance for tasks like drilling sheet metal fasteners, replacing bolt holes, installing brackets, and creating wire harness mounts (non-precision applications),
--- The 4341 high-speed steel (HSS) offers high hardness, excellent wear resistance, and good toughness.
--- Gold and Black finish can enhance the corrosion and wear resistance of twist drills
--- The 135° point angle ensures superior machining stability, delivers higher drilling accuracy, and enables smoother chip evacuation
Useful Tips:
---The 4341 high-speed steel (HSS) drill bit is designed for medium-to-low load machining and should not be used on hardened steels, high-alloy steels, thick stainless steel, or other ultra-hard materials.
---Drill Bit Clamping: The drill bit must be securely clamped, but excessive force must be avoided. Ensure the drill bit is perpendicular to the workpiece surface—tilting can cause breakage or hole deviation.
---Test Drilling on Scrap Material: Always perform a test drill on scrap material first to verify proper speed and feed rates before machining the actual workpiece.

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 $8 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 CoCud 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.
