Reviews Low Hardness

50Pcs Twist Drill Bit Set HSS Shank Titanium Coated High Speed Steel Mini Drill Bit Micro Exactness 1/1.5/2/2.5/3mm Perfect for Wood Plastic Steel and Aluminum Alloy

The main material is high-speed steel, with titanium and nitriding treatment.High speed steel is more abrasion resistant and durable than other metal materials. good wear resistance and durability..
High Quality: suitable for drilling holes in alloy steel, wood, nonferrous metal, cast iron and hard plastics.Mainly for thinner, low hardness of wood and soft metal hole processing, for high hardness stainless steel and other materials can not be processed..
Easy to Removal Chip: spiral grooves with an oxide coating for quick removal..
Surface Titanium Coated: Increase the HARDNESS of the drill bit, Strengthen heat dissipation, make bit more WEAR-RESISTING..

2 pcs tungsten steel bar pendant necklaces for couples and lovers, 1 silver bar necklace and 1 black one, friendship necklace for boys and girls, gorgeous pendant chain for people who like clean and simple design, Easter gifts for kids.
Material: tungsten carbide, tungsten steel is known for its super hardness & flawless quality, the hardness is about 4 times over titanium steel, great material for long lasting jewelry without any fading or scratches. The density is about 1.5 times over titanium steel, it makes the pendant having a good weight to it. Hypoallergenic and outstanding tarnish resistance. Tips: the super hardness of tungsten carbide pendant lead to impact toughness declining, so please avoid falling down and impact..
