Steel Twist Drill Bits
M35 5% Cobalt Steel Twist Drill Bits
A nice-to-have imperial fractional inch bit set for repeated drilling in metals
M35 Grade Cobalt Steel
Cobalt drill bits are not made of pure cobalt, but rather a steel alloy with certain percent cobalt. The 5-percent alloy is known as M35 grade. The cobalt increases the strength of the steel and makes it more heat-resistant.
Lowest Cost Per Hole Drilled
Cobalt bits are more expensive than ordinary HSS drill bits. But if you regularly drill metals, they are a good investment since they tend to last longer.
With an extended life, you can lower the cost per hole drilled.
