ZFYQ Drill Tap Bits Set 1/4" HSS Thread Cutting Tool Hex Shank for Wood Plastic Thin Aluminium, 6 Pieces

• 6 sizes: M3x0.5, M4x0.7, M5x0.8, M6x1, M8x1.25, M10x1.5.
• 6 steel drill bits, suitable for drilling wood, plastic, fine copper, aluminium and other soft metals (5-6 mm), not for hard materials (e.g. sheet steel).
• Convenient fittings, 1/4 inch hex shank, quick and easy change. Self-centering point, requires no assistance to drill or punch the centre. Drilling and tapping at the same time, one-step machining. Significantly reduce processing steps, save time and improve work efficiency.
• When drilling a hole, water should be injected at the same time to cool the drill bit. This will help you increase the value of tutorials. If it is not possible to cool the drill while drilling, the drilling speed should not be too high and you should not drill too frequently.
• The composite tap is best used on bench drill or tapping. The thickness of the piece is less than 5 mm. When using, the lubricant is applied to the tap. If you use the hand drill, the thickness should be less than 2mm, otherwise the tap will break easily (because the hand drill can not always be operated vertically and at constant speed).

Detail: ● Color: Gold ● Application area: metal processing ● Material: HSS 4241 very high speed steel ● Working angle: 90 ● Screwdriver: 1/4" hex screwdriver (6.35mm) ● Surface treatment: titanium coating ● It can be used with cordless electric drill or column drill ● Type: Standard Shank Drill ● Size: M3, M4, M5, M6, M8, M10 Feature: ► Multi-purpose bits and other tools with standard connectors. Metric thread M3-M10. ► Spiral groove design allows drilling and tapping at the same time. The top of the tip can also be milled at the orifice. ► Use a single cutting head for drilling, tapping and deburring/counterbore. There is no need to purchase 3 different tools to perform these operations. It allows you to save on the purchase of more tools and reduce working time, since there is no need to change the drill frequently. Step: Use a drill bit, then perform a thread treatment with a speed of light and cutting oil. Do not drill at high speed. After finishing the wire, use the pin to return (back). NOTE: 1. It is recommended to add a little oil (cutting oil) before starting treatment to ensure easier work and longer life of the cutting head. 2. Application: HSS 4241 steel is suitable for low hardness materials such as wood, aluminum and iron. 3. These drills are not suitable for processing hard metals (×such as steel×)!
