Product Description:

Before starting drilling with the HIDOTOL Cobalt Twist Drill Bit Set 115Pcs, it is important to follow some warm tips to ensure a smooth and efficient drilling process. Make sure to wear masks and gloves for safety. Additionally, it is recommended to keep the drill cool and avoid continuous use to prolong its life. Add coolant if necessary to keep the drill bits in good condition. When drilling, ensure that the bits are vertical to the object being drilled and maintain stability to avoid breakage. For drilling metals, it is highly recommended to use a drill press for stability and precision.

Specifications:

The HIDOTOL Cobalt Twist Drill Bit Set 115Pcs is made of HSS M35 (Cobalt 5%) and features a fully ground process. The drill bits have a 135-degree split point, a spiral flute type, and a round straight shank. The set includes 29 fractional size drill bits ranging from 1/16” to 1/2” by 1/64" increments, 26 letter sizes from A to Z, and 60 numbered wire gauges from #1 to #60. The cobalt content in the drill bits increases their heat and wear resistance, making them suitable for cutting through hard metals such as stainless steel, cast iron, high-temperature alloy, and titanium alloy. The high-speed steel M35 (Cobalt 5%) ensures high strength, hardness, and durability, extending the tool's life.

Features:

The 135-degree split point with a round straight shank ensures self-centering to prevent walking during drilling, making the process precise and faster. The 2 flutes form twist design helps clear particles faster, reduces friction, and generates less heat for a cooler drilling performance. The set comes with a drill bits holder with a size index for easy storage and organization, allowing users to quickly find the right size they need.
