What does M42 cobalt mean?

What does M42 cobalt mean?

M42 is a molybdenum series high-speed steel alloy with an additional 8 or 10 percent cobalt. It is widely used in metal manufacturing industries because of its superior red hardness as compared to more conventional high-speed steels.

Which is better cobalt or titanium bits?

Cobalt bits tend to be quite expensive. However, they are more durable and long-lasting than other options, including titanium. Because of this, they can often save you money in the long run. It depends on whether you want to spend more money now or later.

Is cobalt good for drill bits?

Cobalt drill bits are incredibly strong. Cobalt bits are able to cut through the most hardened metals, including bronze, cast iron, stainless steel and titanium. They are also able to cut through weld seams. The cutting edge on a good quality cobalt bit should last for longer than a standard HSS bit.

What is M42 cobalt drill bits?

Bosch Cobalt M42 Metal Drill Bits are engineered with upgraded M42 alloy, containing 8% cobalt. These hard-core cobalt bits deliver 10X life vs. standard bits, are jobber length, and withstand high-heat applications. The thick web-helix design delivers fast material removal and increased stability.

Which is better M35 or M42 cobalt?

An M35 (5% cobalt) drill bit will drill the majority of metals most people will need to drill. An M42 (8% cobalt) drill bit will drill harder metals however will also be more prone to breakage due to its inceased brittleness.

What is the difference between M35 and M42 cobalt drill bits?

Q: What is the difference between M35 and M42 cobalt steel? A: M35 and M42 refer to the percentage of cobalt in the cobalt steel alloy. M35 is five percent cobalt whereas M42 has eight percent.

Does Dewalt make cobalt drill bits?

Built for speed and long life, DEWALT Industrial Cobalt Alloy drill bits powers through hard metals with ease. …

Will cobalt drill hardened steel?

DRILL BIT MATERIALS IT’s an economical solution for most maintenance drilling applications. Cobalt (HSCO) is considered an upgrade from HSS because it includes 5-8% Cobalt blended into the base material. This is a great option for drilling into harder steel as well as stainless steel grades.

Is M42 better than M35?

What drill bit is strongest?

Carbide (Carb) is the hardest and most brittle of the drill bit materials. It’s used mostly for production drilling where a high-quality tool holder and equipment is used. It should not be used in hand drills or even drill presses. These drill bits are designed for the most demanding and hardest materials.
