18 MM COBALT DRILL BIT FOR METAL 13 MM SHANK RICHMANN C9940
€29.50
Suitable for drilling high-alloy steels and metals with a tensile strength of more than 1000 N / mm2, such as acid-resistant steels and stainless steel.
Metal drill bits made of extremely temperature-resistant high-speed steel with 5% cobalt content Resistant to heat generated during drilling Cobalt drill bits - used for drilling in soft and hard metals.
They are 6 times harder than standard steel drill bits.
The addition of cobalt makes the blade harder and therefore easier to drill into hard material.
Drills are designed for drilling holes in a wide range of steel products, e.g. alloy steel, stainless steel, structural steel, carbon steel, acid-resistant steel, heat-resistant steel, gray cast iron HSS-Co metal drill bits made of high-speed steel alloy with 5% cobalt. 135 ° point angle and chamfer correction make it easy to drill holes without scoring.
Due to the high temperature resistance of the alloy, they are ideal for drilling holes in difficult-to-cut materials such as stainless steel, acid-resistant steel, heat-resistant steel, etc.
