Bivethoi Reduced Shank Twist Drill Bits 16mm Black Nitride & Gold Titanium Coated High Speed Steel 4341 with 10mm Shank for Drilling Steel Plate

Wide Applications Can be used for drilling stainless steel, aluminum alloy, iron, copper, brass, metal, wood and plastic materials. Perfect tool for maintenance departments, machine shops, and other industries. Suitable for hand drill, table drill processing equipment, etc.. Suitable Lubricant is conducive to cutting or cooling, making cutting easier, improving smoothness and dimensional accuracy. It can help to extend the service life of tools in tapping operations. Reduced Shank Drills Reduced shank drills expand the size range capacity of a portable drill chuck. Common flute and overall length for minimal adjustment during tool changes. Titanium and Nitride Coatings Premium gold titanium and black nitride dual coatings can apply lubricant better for smoother drilling and is more durable and corrosion resistant than the regular black surface. Sharp Spiral Flutes Sharp Spiral flutes provide neat and smooth cuts. High cutting edge strength, fast cutting speed. Spiral groove facilitates the export of metal chip, saving time and effort in operation.

• Enhanced cutting performance: The twist drill bit is made of high-strength alloy steel, combined with a special heat treatment process, to provide higher cutting strength and speed, suitable for heavy duty applications and improve work efficiency.
• Innovative half-shaft design: Unique shaft diameter reduction design makes it compatible with a wider range of portable electric drills and bench drills, reducing adjustment time during tool change.
• Advanced anti-rust coating: The use of blue oxide and titanium alloy double-layer coating technology provides excellent corrosion and wear resistance while reducing friction, improving lubrication and extending service life.
• Wider range of materials: Reduced shank drill are suitable for a variety of metal materials, including stainless steel, aluminum, brass, plastics, and composites, to meet a wide range of industrial and personal project needs.
• Precision drilling: The newly upgraded sharp spiral cutting edge ensures a neat and smooth cut every time you drill, reducing burrs and scrap and increasing overall efficiency.
