Tungsten Powder and Cutting Tools:

Rising tungsten powder prices are reshaping the cost structure and competitive logic of the cutting tool industry. As a core material for cemented carbide tools, tungsten powder directly influences tool performance, stability, and manufacturing strategy, accelerating the shift from price-based competition toward value-driven solutions.

Drilling tools for drilling

The general term for the entire drilling pipe column and its joints used in drilling construction (excluding casing for borehole protection). The drilling tool consists of an active drill rod, a drill rod, a core tube, and a bottom end reamer and drill bit. If necessary, a settling tube or drill collar may be added to the upper part of the core tube. The main function of drilling tools is to transmit drill bit pressure and rotational torque to the drill bit during the drilling process of rock formations, and to deliver drilling flushing fluid to the bottom of the hole to collect rock and mineral cores.

The difference between electric drills, impact drills, hammer drills, and pickaxes

A handheld electric drill simply relies on a motor to drive the transmission gear and increase the rotational force of the drill bit, allowing it to scrape through materials such as metal and wood.

Electric drills can be divided into three categories

Handheld electric drill: The power is the smallest, and its use is limited to drilling wood and as an electric screwdriver. Some handheld electric drills can be converted into specialized tools according to their purpose, and there are many uses and models available 2. Impact drill: There are two types of impact mechanisms for impact drills: dog tooth and ball bearing.

Which type of titanium alloy drill bit is good

Considering the material properties of titanium alloys. Should be selected for materials with weak affinity for the material. Hard alloys containing cobalt are definitely a good choice. Take the following measures: increase the top angle, grind the angle between the two edges to 135-140 degrees, and increase the back angle at the outer edge of the drill bit by 12-15 degrees. Repair the length of the small horizontal blade to 0. 08--0. 1. To reduce the axial force of drilling. Cobalt titanium alloy drilled well! If using a high-speed steel drill bit, the cutting speed is 7-12m/min, the feed rate is 0.05-0.2mm/r. If using hard alloy, v=25-60m/min, f=0.050.15m/r. When drilling shallow holes, the cutting fluid can be selected as electrolyte, which consists of approximately 7% -10% succinic acid, 7% -10% triethanolamine, and 7% -10% glycerol. Boric acid 7% -10%, sodium nitrite 3% -5%, the rest is water. When drilling deep holes, you can choose to add No. 30 mechanical oil to kerosene in a ratio of 3:1 or 3:2, or you can use sulfurized oil.
