About This

• Solid Bonding Hex Shank: there are more advantages compared to old hex shank drill bits: 1. The bit will not break loose from the hex shank base；2. These drill bits run straight and true
• Shank Not Easily Shaken Off: 5 times higher torque compared to the old hex shank, eliminates radial runout and improves concentricity, higher impact-rated accuracy
• Cobalt M35 Material: High cost, but hardness is up to 67, cut faster and has a long life, up to 12 times compared with the average HSS titanium coated bit
• Hardened Full Grinding Process: Increases wear resistance, sharp and durable, used for stainless steel, cast iron, zinc alloy, titanium, aluminum and hard metal
• Wide Range Of Applications: This product can drilling through hard metals such as stainless steel, cast iron, zinc alloy etc., while the HSS titanium-plated version you usually see can only be used on soft materials such as wood and plastic
• Use Notices: Drill bit should be vertical to the workpiece when used; controling low speed from 200 to 1000 rpm; using cutting fluid will stay cool to make the bit last longer
• Widely used: Whether you're a home DIYer or workshoper of professional drilling, it's a great tool
• Packing List: 10 packs of drill bits in 1/16" cutting diameter
