Which is better M35 or M42 cobalt drill bits?
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.
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 does cobalt do in a drill bit?
The cobalt increases the strength of the steel and makes it more heat-resistant; this is an important factor in drilling hard materials because the friction of metal against metal can produce high temperatures that damage the material or the drill bit.
What drill bits are harder than cobalt?
They last much longer than regular HSS drill bits, and they are good for cutting through any metal, including metal sheeting. Titanium drill bits are harder than cobalt, but because they are coated, they can’t be sharpened. Cobalt drill bits are made of cobalt steel, and they can be sharpened.
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.
Will cobalt drill hardened steel?
DRILL BIT MATERIALS 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.
Which is stronger titanium or cobalt drill bits?
Difference Between Cobalt and Titanium Drill Bits Cobalt drill bits are more expensive, but offer longer life, and are more resistant to heat than titanium drill bits. Cobalt drill bits are also tougher and can drill holes in the hardest metals.
What if I don’t have a 15 64 drill bit?
If you don’t have drill bits graduated by 1/64″. round down and use 7/32″. That will be close enough. Rub a little dry bar soap or candle wax on the lag bolt to lubricate it and make it easier to drive in.
What can I use instead of a 5’8 drill bit?
If you break it down to 16th’s, 5/8ths is 10/16ths. So the next size larger would be 11/16th’s. If you want to stay in 1/8ths, than obviously it’s 6/8ths or 3/4″. If you break it down to 16th’s, 5/8ths is 10/16ths.
