Hymnorq 25PC 1-13mm Metric Ground HSS Twist Drill Bits Set for Softer Metal

Different drill bits are used to drill holes in different materials. If you want to drill holes in hardwood, softwood, plastic, fiber, and soft metals such as iron, brass, aluminum alloy, this set of Hymnorq 19PC 1-10mm metric ground HSS twist drill bits set will be a good choice. These drill bits are made of quality high-speed steel. Therefore, they are much harder than ordinary high-carbon steels and can be sharpened relatively easily with cutting fluid while retaining their strength and durability. The drill bits are made using a grinding process with a smooth surface. It will reduce the friction of the drill bit and material, as well as increase the heat resistance and durability of the drill bit. Please note that the HSS drill bit is not suitable for high-intensity operations such as drilling through hardened steel, cast iron, stainless steel, etc.. These HSS drill bits can be mounted to handheld devices and drill presses. The 135°quick-cut split points are self-centering and can penetrate quickly with less pressure. The bits will not "walk" or "wander". The classic straight shank design allows for accurate centering, fit for standard drill chucks and regular round collet chucks. The set includes 25 metric twist drill bits of 25 sizes: 1mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm, 4.0mm, 4.5mm, 5.0mm, 5.5mm, 6.0mm, 6.5mm, 7mm, 7.5mm, 8.0mm, 8.5mm, 9mm, 9.5mm, 10.0mm, 10.5mm, 11mm, 11.5mm, 12mm, 12.5mm, 13mm. packed in a metal indexed case for convenient storage.

• 135 degree point angle means less force required to remove metal, compared with lower angles like 90° and 118°. Self-centering split point allows you to drill directly to the size needed without any pre-drilling.
• Made of high speed steel; fully ground body construction. High flow spiral design for the fastest removal rate and for thick material.
