Description

M42 HSS Cobalt Drill Bit For Metal , 135 Degree Split-Point Drills

Description of DIN340 HSS Drill Bits:

  1. The cobalt drill bits’ capacity to bore through the toughest materials is truly remarkable.
    They are made from a reinforced alloy of combined cobalt and steel.
    Coated with metal oxide, cobalt bits are heat-resistant and durable.
    Some drill bits have a gold oxide finish that acts as a lubricant.
    The coating helps the bits withstand the extreme friction during prolonged drilling.

How many benefits you get from cobalt drill bits:

Durability


The higher the amount of cobalt in the drill bits, the greater is their heat resistance.

If you want sturdier and high-performing bits, M42-grade will give you satisfaction.

It has 8% cobalt content that makes the alloy material extremely durable.

Another option is M35-grade, which has about 5% cobalt value.

Cobalt drill bits can handle up to 1100 degrees Fahrenheit or 593 degrees Celsius without breaking.

Made From HIGH-SPEED Steel and 5% Cobalt,improve much higher heat resistance because of cobalt steel's high

red hardness, provide strong durable performance compared to typical hss drill bits

Accurate and Neat: 135°Quick-Cut points are self-centering and penetrate quickly with less pressure.
