Attributes:* Drilling Diameter: 20mm / 0.79"* Shank Diameter: 8mm / 0.31"* Drilling Depth: 32mm / 1.26"* Overall Length: 59mm / 2.32"* Material: Diamond, Medium Carbon Steel* Finish: Zinc Plated* Package Included: 1pcs x Diamond Drill BitWhat Is Included:* 1pcs x Diamond Drill BitsApplications & Features:--- The drill bit set with thickened electroplated diamonds has a sharp cutting edge and excellent cutting strength, ensuring high precision and smooth cuts without edge breakage.--- Made of industrial-grade carbon steel, the drill bits have good toughness, high strength, and durability.--- The nickel-plated coating provides great corrosion resistance, wear resistance, and a long service life.Useful Tips:--- When using the diamond drill bits, always add coolant (water) to lubricate and cool down the drilling process. This greatly extends the tool life.--- Use the diamond drill bits at low drilling speeds and pressure for optimal performance.--- These drill bits are not suitable for use on concrete or for drilling deeper than about 1/2 inch.--- Ensure that the hole is entered smoothly without applying side pressure to prevent damage to the drill bit.
