Feature(may vary by option.)

●★ Twist Drill Dimensions ---Drill Diameter: 6.8mm; Tool Slot Length: 84mm; Shank Diameter: 6.8mm; Overall Length: 156mm / 6.14"; Tool Flute Type: Spiral ; Hardness: HRC63-66; Processing Technology: Complete Polishing and Turning Pressure
●★ UNIVERSAL PURPOSE --- Suitable for drilling metal materials such as stainless steel, aluminum alloy, iron, copper, brass, hardwood and hard plastic, and is suitable for repair departments, machine workshops, etc. Used for drilling and tabletop drilling machines
●★ SCREWTED GROODS --- Sharp helical grooves provide a fast, orderly and smooth cut. The spiral groove makes the outlet of metal debris easier, saving operation time and effort. Designed with a small pocket to keep the coolant close to the cutting blade
●★ HIGH SPEED STEEL --- Straight shank bit is made of high speed steel 6542, which has high hardness, good toughness, high strength and abrasion resistance. Black oxide treatment can enhance hardness, rust resistance, and wear resistance
●★ HELP TIPS --- Choosing the right lubricant will help you cut and cool! Keep cool and gentle when using. When using a hand drill, it is recommended to operate speeds of 100-1000 r/min. When used correctly, the life of the hemp drill is greatly extended
