Carbide Step Drill For Stainless Steel And Aluminum
Product application
Excellent adhesion between coating and substrate ensures processing stability and prolongs tool life
Smooth coating surface reduces cutting resistance and improves tool wear resistance
Suitable for: Steel, stainless steel, aluminum, cast iron and high hard steel,Widely used in aerospace, automobile manufacturing, mobile phone manufacturing, chip packaging and other industries.
Product advantages
OPT is different: a pioneer in technology and innovation for more than 25 years.
The coating used by OPT is 40% stronger than the ordinary coating.
New "nanostructure" coating technology is adopted, and the coating structure is compact.
Excellent adhesion between coating and substrate ensures processing stability and prolongs tool life.
Smooth coating surface reduces cutting resistance and improves tool wear resistance.
The application of our cutting tools in the watch industry
Our drill bits are specially designed to absorb strong impacts.
The numbers speak for themselves. When tested under the same conditions, our bits outlived those of other companies by more than 30%.
1.The tip of the carbide bit is easy to crack
2.The point is drilled with a reinforced tungsten steel bit
You can use specially developed application tools that are used by trained professionals
Technology tell your production technicians. You can also tell us your needs, our company to provide you with a full set of solutions
Customization a variety of specifications
According to customers' different processing conditions, customized carbide bits or powder metallurgy high speed steel bits
Shank quare size according to customer requirements to meet different fixtures.
Full coverage, focus on design
According to the different processing materials, we can design different drill products! This will bring customers higher efficiency and lower production costs!
Excellent groove handling
The high precision processing method is used to treat the finish of the groove and the iron chute, which reduces the cutting resistance of the alloy bit and can discharge the iron chute faster, thus reducing the heat of the tool and improving the life of the bit
Drill point detail handling
Excellent tip detail treatment, can increase the strength of the drill tip, reduce the carbide bit's edge, increase the life of tungsten steel bit, improve the production efficiency of the factory.
