6Pcs 1mm Micro Engraving Drill Bits, Titanium Coated High-Speed Steel

Description of Micro Engraving Drill Bit: The Micro Engraving Drill Bit is suitable for DIY drilling and carving of resin, amber, wood, plastic, and soft metals. It is important to note that this drill bit is not suitable for use with high-speed electric drills or on materials that are excessively hard.

High-speed Steel: This drill bit is made of high-speed steel, which provides excellent toughness and hardness, making it resistant to breakage and enabling easy chip removal.

Color Quenching Treatment: The drill bit undergoes a color quenching treatment, which increases its hardness and enhances its overall efficiency during use.

Titanium Plated: Furthermore, the drill bit is titanium-plated, giving it higher wear resistance and a lower friction coefficient. This results in a longer service life and reduces the accumulation of chips during use.

Specifications: The Micro Engraving Drill Bit features a round shank, spiral flute type, and a Rockwell hardness grade of 63-66 HRC. The diameter of the twist drill bits is 1mm (0.04 inches), with a shank diameter of 2.35mm (0.09 inches). The total length of the drill bit is 49.5mm (1.95 inches), and the drill bit length is 21mm (0.83 inches).

Material and Cooling Style: Made of high-speed steel, this drill bit offers stability during operation and is designed to adapt to various cooling conditions, such as oil mist, water, oil, and air cooling.

Design and Applications: The spiral flute design of the drill bit allows for quick and efficient cleaning of chips, while the sharp cutting edge provides a smooth and glitch-free cut. This makes the drill bit suitable for use with electric drills, hand electric drills, and impact electric drills, particularly for DIY projects involving resin, amber, and wood drilling.
