Feature(may vary by option.)

●★ Drill Bit Size --- Cutting Blade Diameter: 0.7 inches (18 mm); Rod Diameter: 0.5 inches (12.7 mm); Blade Length: 3.1 inches (80 mm); Overall Length: 5.9 inches (150 mm); Hardness: HRC65-66; Cutting Direction: Right Hand;
●★General Purpose--- Widely used for drilling stainless steel, aluminum alloy, cast iron, high carbon steel, copper, hardwood and hard plastic. Used for drilling and tabletop drilling machines. Clamp bits expand the dimension range of portable drill chucks
●★ 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
●★ 6542 High Speed Steel --- Hemp flower drill has high hardness, toughness and high strength. Black nitride coating has excellent abrasion resistance, corrosion resistance, and high temperature resistance. Provides better lubricant application and provides smoother drilling
●★ Useful Tips --- Proper lubricant is beneficial for cutting or cooling, improving dimensional accuracy, and extending tool life. Lower forward and backward speed Made of solid aluminum and wood

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.

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.
