Description:

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.

135 Degree Split Point

The flater the drill, the smaller the chip width. This means less force required to remove metal, compared with lower angles like 90 and 118. This is important on hard stuff, because your power requirements are already more than mild steel, so making the chip load less helps. It also reduces heat since less surface area is generating the cut.

Lowest Cost Per Hole Drilled

Cobalt drill bits are more expensive than other drill bits, but if you regularly drill through metal, they are a good investment since they tend to last longer. With an extended tool life, Migiwata cobalt drill bits will give you the lowest cost per hole drilled.

For Drilling Stainless Steel

This set of Migiwata M35 cobalt steel drill bits are particularly successful in cutting through hard metals such as stainless steel and cast iron, although they can be used for softer materials, too.

Tests shows that the M35 cobalt steel drill bits can penetrate a 5mm-thick 304 stainless steel plate in 5 seconds.

Not Suitable for Hardened Steel

M35 grade cobalt drill bits are NOT suitable for hardened steel, high carbon steel and heat-treated steel by the experiences of some customers, although some others said they worked well with hardened steel.

Cooling Liquid Required

Please use with cooling liquid to prolong the working life of the drill bits and to avoid overheating and breakage.

Buy cobalt hss drill bits from Amazon.com

Description:

The Drill America DWD29J-CO-PC Qualtech jobber length drill bit set contains 29 cobalt steel drill bits with gold oxide finish in inch sizes 1/16" to 1/2" (1/64" increments). A self-centering 135-degree split point penetrates hard material without a pilot hole and produces smaller chips that reduce clogging compared to a 118-degree point. Cobalt steel provides extended tool life compared to high-speed steel drill bits, and maintains the tool's toughness and hardness in high drilling temperatures. A gold oxide finish acts as a lubricant and provides wear resistance, and the round shank accommodates most drill chucks. The set comes in a plastic index case with labeled compartments for identification and organization. Drill bits conform to American National Standards Institute (ANSI) standards.

Drill bits are cutting tools used to make holes in a range of materials using machines such as handheld portable drills, machining centers, and lathes. Drill bits come in a variety of lengths and types, the most common of which is the twist drill bit. The round, twisted shaft of the twist drill bit typically has two cutting edges and flutes. The helical twist of the flutes brings chips up and away from the cutting edges and allows for coolant to reach the cutting edges. Jobber length twist drill bits, the most common length of twist drill bit, offer a good compromise of length and reach to work with the widest range of materials and applications. Mechanic's length twist drill bits (also called maintenance length) are a little shorter than jobber length and less prone to deflection when drilling. Short length twist drill bits (also called stub or screw-machine length) are the shortest and stiffest twist drill bits, helping to reduce the chance of deflection or breakage when drilling. Reduced shank drill bits (also called Silver and Deming drill bits) have a shank that is smaller in diameter than its shaft, permitting drilling machines with either a 1/2" or 3/4" drill chuck to create large holes. Long length twist drill bits (also called taper length) are a little longer than jobber length, allowing for deeper holes and longer reach. Extra long twist drill bits (also called extension) are longer than long length twist drill bits for greater reach or for drilling deeper holes.

Drill America manufactures cutting tools such as drill bits, taps, dies, counterbores, countersinks, end mills, and reamers. The company, founded in 1927, is headquartered in Miami, FL.
