A straight drill bit, also known as a wind drill bit, is a rock drilling bit used for rock fragmentation. Mainly used in coal mines, tunnels, etc., it is used in conjunction with B22 rock drilling rods

The manufacturing process of the I-shaped series drill bits is simple, easy to regrind, reliable in operation, and has strong adaptability to rock mass performance. Often used in conjunction with lightweight internal combustion, electric, pneumatic, and hydraulic rock drills, to drill rock holes with a diameter of D50mm or less in various types of rocks. Due to its low cost and other characteristics, it is still the main type of drill bit used in medium and small diameter rock hole drilling projects in China's mining industry. The specifications of MITOYO drill bits include: 28, 30, 32, 36, 38, 40, 42, 50, 60, etc., suitable for mining in coal mines, iron mines, gold mines, copper mines, lead zinc mines, and other mines, as well as railway, tunnel, railway, highway and other engineering construction.

1. The specifications and varieties range from diameter 20 to diameter 30, diameter 32 to diameter 43, diameter 45 to 60, etc.

2. The material selection is reasonable, and the manufacturing strictly follows the ISO9001 quality management system for quality control. Not only does it focus on the internal quality of the product, but the surface treatment of the product is also very fine.

3. Scientific design, beautiful appearance, packaging, and very prominent traceability markings.

4. The product structure is reasonable for high, medium, and low-end products, meeting the needs of different customers. The alloy classification is suitable for rocks with different hardness coefficients.

One shaped, cross shaped, ball toothed, coal drill bits, and high and low wind pressure down hole drill bits are used in energy, metallurgy, geology, coal, water conservancy, chemical industries, mining, road construction, etc.
