6Pcs Twist Drill Bit 3Mm Dia 80Mm 1/4" Hex Shank High-Speed Steel Bits

Titanium coated twist drill bits are commonly used in drilling applications because of their strength, durability, and resistance to wear and tear. These drill bits have a titanium nitride coating that increases their hardness and reduces friction between the bit and the material being drilled. The twist drill bit is made of high-speed steel, and the surface is plated with titanium. The titanium coating makes the bit more durable and resistant to wear and tear, which is important when drilling through tough materials like metal. This means that the bit will last longer and need to be replaced less often. Smooth surface finish for long service life. The titanium coating also reduces friction and heat buildup, which can help prevent the bit from becoming dull or overheating during use. This is particularly important when drilling through metal, which can generate a lot of heat and cause the bit to wear out quickly. Wide applications for drilling materials such as hard metal, malleable iron, aluminum, wood, plastic etc. Great replacement for your dull drill bit to improve work efficiency. Precise drilling and consistent size of resulting components can lead to a more reliable and accurate performance in the finished product. Comes in a variety of sizes to accommodate a wide range of drilling needs. Suitable for use in both handheld drills and drill presses. Notice: Please keep cool and gentle using, the working life of the twist drill bits can be largely prolonged by proper usage. When using a hand-held electric drill, pay attention to speed adjustment. The larger the drilling diameter, the slower the drilling speed should be chosen. When the chip evacuation has a problem, go back and remove the chips in time.
