Girihe 13 PCS Metal Drill Bits, 1.5-6.5mm Drill Bit Sets Steel Drrill Bits for Metal Metall Dril Bit fo r Hard Steel, Dril Bitt for Metall Wood Plastic Stainless Stel & More

• 【Drill Bits For Metal】A box of Hss Drill Bits contains 13PCS, with sizes ranging from 1.5mm to 6.5mm, specifically: 1.5mm, 2mm, 2.5mm, 3mm, 3.2mm, 3.5mm, 4mm, 4.5mm, 4.8mm, 5mm, 5.5mm, 6mm, 6.5mm.
• 【Metal Drill Bits】Drill Bits for Metal are crafted from M35 cobalt steel, which is fortified by the addition of molybdenum and cobalt to form a tough alloy. This alloy boasts a Rockwell hardness of up to 67, making it highly heat-resistant. As a result, these drill bits offer much faster cutting speeds and a significantly longer lifespan, up to twelve times that of an average HSS drill bit.
• 【Drill Bit Sets】The 135° Quick-Cut points are self-centering and can penetrate materials quickly with minimal pressure. They won't ""walk"" or ""wander"". The straight shank ensures a firm grip and precise centering, making them compatible with standard drill chucks and regular round collet chucks. To achieve maximum efficiency, they must be used and operated at the proper RPMs.
• 【Steel Drill Bits For Metal】The Hss Drill Bit Set undergoes full grinding processing, which results in a smoother drill bit surface. This reduces friction and allows for faster cutting speeds.
• 【Metal Drill Bits For Hard Steel】Metal drills are suitable for a variety of materials, including wood, plastic, stainless steel, thin metal plates (steel and aluminum), body plates, and low carbon steel. They are highly effective for these projects but are not suitable for use on concrete or masonry.

You will receive a 13-piece collection of titanium-coated twist drill tools for drilling. The drill bit is constructed from HSS high-speed alloy, which is then enhanced with a titanium plating that offers high wear resistance.A box of Hss Drill Bits contains 13PCS, with sizes ranging from 1.5mm to 6.5mm, specifically: 1.5mm, 2mm, 2.5mm, 3mm, 3.2mm, 3.5mm, 4mm, 4.5mm, 4.8mm, 5mm, 5.5mm, 6mm, 6.5mm. Our drill bits are significantly more heat-resistant than regular drills. The 5% cobalt HSS M35 material helps to extend the tool's lifespan. The straight shanks ensure secure clamping and accurate centering, making them compatible with standard drill chucks and regular round chucks. Product application: Suitable for drilling wood, thin aluminum plates, plastics, and so on. Note: These drill bits are not designed for drilling high-hardness metals or cement.
