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.

Migiwata Metric M35 Cobalt Steel Extremely Heat Resistant Twist Drill Bits with Straight Shank Set of 50pcs in 5 Sizes(1, 1.5, 2, 2.5, 3mm) to Cut Through Stainless Steel Cast Iron and Hard Metals

Buy dewalt cobalt drill bits from Amazon.com

Description:

Different types of drill bits are used to cut holes in different types of materials.
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.

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;
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.

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

Notice: The working life of the drill bits can be largely prolonged by using with cooling liquid.

Specifications:
Material: M35 Cobalt Steel
Angle Point: 135 Degree
Flute Type: Spiral
Hardness: Rockwell 67
Shank Type: Straight Shank

You will get:
1mm Cobalt Drill Bit x 10pcs
1.5 mm Cobalt Drill Bit x 10pcs
2 mm Cobalt Drill Bit x 10pcs
2.5 mm Cobalt Drill Bit x 10pcs
3 mm Cobalt Drill Bit x 10pcs

  • M35 Cobalt Steel - Manufactured from M35 cobalt steel, with molybdenum and cobalt added to creates a hardened alloy, measuring Rockwell hardness up to 67, for much faster cutting and extra longer life span, with up to twelve times when compared with an average HSS drill bit.
  • No Center Punch Needed - the 135 quick-cut points are self-centering and penetrate quickly with less pressure. Will not "walk" or "wander"
  • For Stainless Steel - Particularly successful in cutting through hard metals such as stainless steel and cast iron, although they can be used for softer materials, too. Not for hardened steel / high carbon steel. Try to adjust the RPM when it fails to penetrate.
  • 50pcs Set - The set includes 50pcs of M35 cobalt steel twist drill bits: 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 10pcs of each size
