Drill America 115 Piece m42 Cobalt Drill Bit Set 1/16 -1/2 A-Z 1-#60 D/ACO Series
Cobalt steel tools are similar to high-speed steel, but with more cobalt for improved performance when cutting harder metals such as stainless steel....
Gold oxide is a thinner oxide surface treatment than black oxide typically used to identify cobalt steel tools.
Round shanks allow use with a wide variety of toolholding systems.
When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging.
KEO 53518 Cobalt Steel Single-End Countersink Set Uncoated Bright Finish 82 Degree Point Angle 5/16 - 5/8 Head Diameter
Cobalt steel tools are similar to high-speed steel, but with more cobalt for improved performance when cutting harder metals such as stainless steel or nickel alloys.
Uncoated tools feature just the base substrate without any additional treatment or coatings and are suitable for a wide range of applications.
Cobalt M42 drill bit – provides upgraded M42 Cobalt jobber-length bits designed for durability, high heat resistance and Hardened surface for stainless steel, cast iron, titanium, light-gauge metal and aluminum.
Enhanced M42 alloy material – contains 8% Cobalt alloy that delivers 10x life vs. Standard bits.
High-heat resistant bits – withstand high-temperature applications for extended periods of time.
MADE FROM HIGH-SPEED STEEL AND 5% COBALT: improve much higher heat resistance because of cobalt steel's high red hardness, provide strong durable performance compared to typical hss drill bits.
CAN BE REPEATEDLY SHARPENED AS NEEDED: cobalt drill bit's hardness is uniform throughout the entire material, so that can be repeatedly sharpened without damaging the cutting edge allowing it to drill more than hss drill bits.
APPLICATION: best used for removing damaged bolts and screws, or drilling a pilot hole for a screw extractor.
INCLUDE: 2pcs 5/64 inch, 2pcs 7/64 inch, 1pc 5/32 inch, 1pc 1/4 inch and 1pc 19/64 inch cobalt left hand drill bits with case.
