Cobalt Drill Bit Set by HIDOTOL

Product Description: The HIDOTOL Cobalt Twist Drill Bit Set is made of high-quality HSS M35 (Cobalt 5%) material. The process of fully grounding ensures its durability. With a split point of 135 degrees and a spiral flute type, this drill bit set guarantees precise and fast drilling. The round straight shank and self-centering design prevent walking and provide stability during drilling.

The set includes 115 pieces, which consist of 29 fractional sizes ranging from 1/16” to 1/2” in 1/64" increments, 26 letter sizes from A to Z, and 60 numbered wire gauges from #1 to #60. The HSS M35 Cobalt material increases the heat and wear resistance of the drill bits, making them ideal for cutting through hard metals like stainless steel, cast iron, high-temperature alloy, and titanium alloy.

The two-flute form twist design helps clear particles faster, reducing friction and heat for a cooler drilling performance. For easy storage and organization, a drill bit holder with size indexes is included in the set. This holder also allows for quick access to the desired size.
