Feature(may vary by option.)
●1 ) High-visibility targets for primary 19 hole sizes; come with 19 sizes (3/16", 9/32", 3/8", 7/16", 17/32", 5/8", 11/16", 25/32", 7/8", 29/32". 31/32", 1", 1-1/16", 1-1/8", 1-5/32", 1-7/32", 1-9/32", 1-5/16", 1-3/8"), so you can drill up holes with different diameters, saving your time and efforts to change bits.
●2 ) Genuine M2 high-speed steel with titanium coating ensures durability and sharpness, reduced friction, and cooler operation.
●3 ) Excellent performance in heat, corrosion and rust resistance, extending the life of the cutting edge even in extreme temperatures.
●4 ) 19 size multiple hole stepped up bits, have many steps which contain multiple diameters, convenient to drill different hole size by using a step drill rather than many drills, ideal for DIY projects at home, garden, workshop etc.
●5 ) The split point tip is at 118 degrees to increase the wear resistance. The two flute design provides a smoother cutting, allows the material particles escape easily for a much more clean drilling operation, can be used on electrical drill, cordless drill etc.
