Drill America DWDCO44P12 #44 Cobalt Drill Bit (Pack of 12), DWDCO 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 or nickel alloys.
Gold oxide is a thinner oxide surface treatment than black oxide typically used to identify cobalt steel tools.
performance is similar to uncoated 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.
Ideal for drilling in tough, high tensile strength materials.

【M35 COBALT HIGH SPEED STEEL】1/8" drill bits for metal made from M35 Cobalt High Speed Steel and contain 5% Cobalt, which increases wear-resistance, durability and extra longer life span, so that the drill bits last through multiple uses.
【135° SPLIT POINT】135°quick-cut pilot split points are self-centering and can penetrate quickly with less pressure. Straight shank of this cobalt steel drill bit allows for firmly holding and accurate centering and makes drilling precise and faster.
【FULLY GROUND PROCESS】Fully ground spiral groove design clears particles quickly, decreases friction and heat for faster drilling performance.
【PROFESSIONAL & WIDELY USE】Jobber drill bits perfectly Suitable for drilling holes as Stainless Steel, Copper, Cast Iron, Galvanized Pipe, Aluminum Alloy, Wood and Other Softer Metals. Not for Glass or Ceramic Materials.
【EASY USE & STORAGE】This metal twist drill bits set includes 10pcs 1/8" Cobalt Drill Bits, This drill bit fits the majority of power drill currently on the market and come with a portable plastic case for easy storage and DIY, household maintenance and repair.
