Why Should You Buy the Dewalt DT4957-QZ Cobalt Metal Drill Bits?

The level of heat resistance and strength of your drill bits are some of the most important things to consider when drilling surfaces and objects made of harder metals, such as stainless steel, bronze, cast iron, and titanium. Standard drill bits are made with a combination of alloy steel mixed with 5-7 percentage cobalt, a melting point of 1495°C and a boiling point of 2927°C. Thus, high temperatures are produced when drilling hardened materials and, as a consequence, those materials or the drill bits can be damaged. But the Dewalt DT4957 cobalt drill bits are one of the best and exceptionally powerful drill bits designed for operating at much higher speeds than any conventional drill bits.

These Drill Bits Dewalt DT4957 withstand extreme heat: this means that you can work for long periods without the need for cooling or cutting fluid. The Cobalt Drill Bits Dewalt DT4957 is designed and manufactured with high-performance cobalt alloy cutting steel, optimized geometry, non-slip shaft, and reinforced core, enabling you for 50% faster drilling speed, 2x resistance to breaking, 4x longer service life. Then, these Drill Bits Dewalt DT4957 guarantee an improved performance and the prevention of chuck slipping on the shank. This set of drill bits will come in a plastic box, that prevents the bits from damages and helps you to keep all the pieces always tidy. Whether you want to cut through a wide variety of hardened materials or drill various abrasive objects, when you choose the Dewalt DT4957-QZ extreme cobalt drill bits, you can rest assured that you can withstand any heavy-duty metal drilling projects with maximum drilling speed and higher heat resistance.
