Tungsten Carbide Drill Diameters

Tungsten carbide drill body with casting, forging and fine carbon steel cutting and other production and processing

technology,tungsten carbide drill bits wide field of application. Widely used in coal, gypsum mines and other soft rock drilling, reaming operations,tungsten carbide drill bits into the overall type, two combinations, three and four combinations of four types of combinations. Where monolithic tungsten carbide drill diameter Ф27, Ф28, Ф30, Ф32, Ф34, Ф36, Ф38, Ф42, Ф45 different specifications, the size of the corresponding conventional connection is also not the same, for example, is a regular connection dimensions Ф27 M12/Φ8, Ф28 conventional connection size is M12/Φ8, conventional connection dimensions Ф30 is M12/Φ8, Ф32 conventional connection size M14 × 1.5/Φ8.
