●★ Drill Dimension---Cutting Edge Diameter: 0.5 inches (13 mm); Shank Diameter: 0.5 inches (13 mm); Blade Length: 4.0 inches (102 mm); Overall Length: 5.9 inches (150 mm); Shank Type: Round shank ●★ UNIVERSAL USE --- Widely used for drilling metal materials such as stainless steel, aluminum alloy, iron, copper, brass, hardwood and hard plastic, suitable for the repair department, machine workshop and so on. Used for drilling and tabletop drilling machines ●★ DOUBLE SHIELD --- Dual coating of gold titanium and black nitride provides better lubricant application, smoother drilling and more durable and corrosion resistant than normal black surfaces ●★ HIGH SPEED STEEL --- Straight shank drill is made of 4341 high speed steel, high hardness, good toughness, high strength and high abrasion resistance. Sharp helical grooves provide a fast, orderly and smooth cut ●★ HELP TIPS --- Choosing the right lubricant is beneficial for cutting and cooling. It facilitates cutting, improves dimensional accuracy, and extends tool life. Check various cutting conditions to ensure the tool is properly handled

Description
Information
Drilling with burrred: Reduce the number of holes and check various cutting conditions to ensure proper tool handling
Lower forward and backward speed Use harder aluminum and wood Choose the right cutting parameters When drilling a metal with high hardness needs to be slower than a normal drill.
Wide Application
Widely used for drilling stainless steel, aluminum alloy, iron, copper, brass, hard wood, hard plastic and other metal materials.
Round shank
This universal shank is easy to use with drilling machines and bench drills, and can be used for stable drilling.
Choosing the right lubricant is beneficial for cutting and cooling.
Makes cutting easier, improves dimensional accuracy, and extends tool life.
Twist Drill Bit
4341 high speed steel, high hardness, good toughness, high strength, abrasion resistance, used in mechanics and machinery factories.
Dual coating of gold titanium and black nitride improves lubricant application and makes drilling smooth.
More durable and corrosion resistant than regular black surfaces.
Sharp spiral flute for fast, clean and smooth cutting
Spiral grooves help to drain metal strains, saving you time and effort.
