This set of M35 cobalt steel drill bits are\nparticularly successful in cutting through hard metals such as stainless steel\nand cast iron, although they can be used for softer materials, too. Cobalt\ndrill bits are not made of pure cobalt, but rather a steel alloy with certain\npercent cobalt. The 5-percent alloy is known as M35 grade. The cobalt\nincreases the strength of the steel and makes it more heat-resistant; this is\nan important factor in drilling hard materials because the friction of metal\nagainst metal can produce high temperatures that damage the material or the\ndrill bit. Tests shows that the M35 cobalt steel drill bits can penetrate a\n5mm-thick 304 stainless steel plate in 5 seconds. Cobalt drill bits are more\nexpensive than other drill bits, but if you regularly drill through metal,\nthey are a good investment since they tend to last longer. With an extended\ntool life, Hymnorq cobalt drill bits will give you the lowest cost per hole\ndrilled. NOTICE: Please use with cooling liquid to prolong the working life of\nthe drill bits and to avoid overheating and breakage. This set M35 grade\ncobalt drill bits are not suitable for hardened steel \/ high carbon steel.\nTECHNICAL DETAILS: Material: M35 Cobalt Steel Angle Point: 135 Degree Flute\nType: Spiral Hardness: Rockwell 67 Shank Type: Straight Shank WHAT’S INCLUDED:\n1\/4” Cobalt Steel Drill Bit x 10pcs Plastic Case x 1pc BUY WITH CONFIDENCE: If\nyou’re not completely satisfied with the product quality, please contact us.\nRefund or free replacement.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n \u003cul class=\"a\"\u003e\n \u003cli\u003eCOBALT STEEL - Manufactured from M35 grade 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, ideal for repeated drilling in metalworking.\u003c\/li\u003e\n \u003cli\u003eFOR METALWORKING - Particularly successful in cutting through hard metals(hardness less than HRC38) such as stainless steel and cast iron, although they can be used for softer materials like copper and aluminium, too.

Hymnorq 1/4 Inch Fractional Size M35 Cobalt Steel Twist Drill Bit Set of 10pcs, Jobber Length and Straight Shank, Extremely Heat Resistant, Suitable for Drilling in Stainless Steel and Iron

Style:1/4"(10pcs) OVERVIEW Different types of drill bits are used to cut holes in different types of materials. This set of 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. With an extended tool life, Hymnorq cobalt drill bits will give you the lowest cost per hole drilled.
