There are several types of percussion bits
2022 / 04 / 12
There are eight types of percussion bits. 1, carbide impact drill can be divided into: straight shank impact drill, taper shank impact drill and hexagonal shank impact drill. Use: for clamping on the impact drill, for drilling concrete foundation, wall, brick wall, granite, in order to install expansion bolts, plastic expansion pipe and other fasteners in the hole. 2, if the electric hammer bit is accidentally broken in the inside, the first user should first open the electric hammer collet to the maximum, if there are screws in the collet, you can remove the screws with a screwdriver; Then insert the collet key and turn the collet counterclockwise. Note that the collet is rotated, not the key. If the key is rotated, the bit will clamp more tightly, so just rotate the collet counterclockwise.

There are four basic types of carbide bits: solid carbide bits, indexable carbide bits, welded carbide bits, and replaceable carbide crown bits. Solid carbide bit Solid carbide bits are suitable for use in advanced machining centers. The drill bits are manufactured from fine grained carbide materials and coated for extended service life. The specially designed geometric edge enables self-centering, providing excellent chip control and removal when drilling most workpiece materials.

Processing effect (1) the diameter of twist drill is limited by the aperture, the spiral groove makes the drill core thinner, the drill bit stiffness is low; With only two ribbed guides, the axis of the hole is easy to skew; The horizontal edge makes centering difficult, axial resistance increases, and the bit is easy to swing. Therefore, the shape and position error of the drilled hole is large. (2) twist drill before and after the tool surface are curved, along the main cutting edge of each point of the front Angle, the rear Angle is not the same, the front Angle of the horizontal edge of -55°. Poor cutting conditions; The distribution of cutting speed along the cutting edge is not reasonable, and the cutting speed of the tip with the lowest strength is the highest, so the wear is serious.
