The mine drill adopts a wind drill bit rock drill with a slotted cross hexagonal shank alloy wind drill bit

The body of the wind drill bit is made of 50cr steel hot extrusion, which is made of cast steel, and the top cutter head is made of hard wear-resistant alloy. There are thread buckles with taps and without taps, and those without taps are directly drilled with the drill pipe card.

The types of wind drill bits have a slotted type, column tooth type, cross type, and horseshoe type, which are mainly suitable for mining, coal mining, iron ore, gold mining, roadway, tunnel, tunneling, quarrying, transportation and water conservancy, and municipal construction rock breaking projects, and are suitable for dry and wet rock drilling in medium and hard rocks. It is divided into large alloy, small alloy 8*13, 9*13, etc.
Common models of wind drill bits: φ28 φ32 φ34 φ36 φ38 φ40 φ42, of which 40 models are used.

Wind drill bits, used on rock drills (air drills) machines, the wind drill bits consist of a shank with a tip and two cutting inserts located on a main plane. This is a drill bit that can mitigate sudden changes in the drilling state during drilling work on concrete, etc., and stabilize the drilling operation, so that the drilling efficiency does not decrease even when large chips are generated.
