Description

PACKING LIST: 5 packs of drill bits in 7/16"(11.11mm)cutting diameter, 94mm/3.7inch flute length, 142mm/5.59inch overall length, 135° split point tip. FEATURE: Drill bits made of M2 high-speed steel feature high hardness and wear resistance, making them suitable for machining medium and high hardness metal. Additionally, the nitriding black surface enhances the drill bit's wear and corrosion resistance, further extending the drill bit's lifespan. APPLICATION: The M2 high-speed steel drill bit delivers superior all-around performance, making it the optimal choice for most metal drilling applications, including low/medium-carbon steel, alloy steel, stainless steel, cast iron, and aluminum alloys. When drilling harder materials such as high-carbon steel, stainless steel, and alloy steels, is recommended to use a coolant to reduce wear NOTE: Position the twist drill at 90° to the workpiece. For thick materials, drill in multiple passes to prevent overheating or breakage. For large holes, start with a guide hole. Use coolant to improve efficiency, extend drill bits' life, and reduce material damage. INSTRUCTION: When machining different materials, the spindle speed and feed rate vary. Generally, the harder the material, the lower the spindle speed and feed rate should be. For specific speed and feed rate recommend for common materials, please refer to the details provided on the product page. √FEATURE:
The drill bit is made of M2 high-speed steel material, it has high hardness and wear resistance, suitable for processing medium-high hardness materials
Nitriding Black can enhance the surface properties of the drill bit, improving its wear resistance and corrosion resistance, thereby extending the drill bits' service life and operational efficiency.
The 135-degree tip angle drill provides excellent processing stability and is well-suited for harder materials. It effectively reduces the risk of cutting-edge chipping, thereby improving drilling efficiency and hole quality.

APPLICATION:
The drills are suitable for hard metals, such as steel, alloy cast iron, stainless steel, iron, copper, aluminum alloy, and cast iron. They are also effective in plastics and wood.

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 $3 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 PATIKIL 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.
