Precautions for Twist Drill Bit Grinding
1. Grinding bits generally use grinding wheels with a particle size of 46-80 mesh, and aluminum oxide grinding wheels with medium to soft hardness are preferred. It is required that the grinding wheel runs smoothly, and grinding wheels with large runout must be trimmed. In order to smoothly grind the transverse edge of the drill bit, the outer corner of the grinding wheel must be trimmed to a smaller radius. If the radius of the fillet is too large, it will damage the main cutting edge when grinding the transverse edge.

Is It Common to Punch Holes on Decoration Beams?
1. Nowadays, it is common to punch holes in beams during the decoration process. Because no matter what beams or columns are used for load-bearing purposes, they are all reinforced concrete structures with high stability. As long as they are not removed, there is not a problem of drilling holes on them. 2. When drilling holes on the beam, be careful not to make them too large. If
What Is the Safe Position for Drilling Holes on the Beam?
1. The choice of punching holes on both sides of the beam is the safest because the stress on both sides is the smallest and does not have a load-bearing effect. If you choose to hit the middle of the beam, it will actually damage the load-bearing effect of the beam. 2. The traditional concept holds that load-bearing beams cannot be perforated, but in fact, they are no
What Should Be Paid Attention to When Drilling Holes on the Decoration Beam?
1. Understand the schematic diagram of each hole position before drilling, understand the structure and internal and external conditions of the house; 2. Clearly mark each hole position and observe the direction of the water and electricity pipelines;
Which Positions Should the Drill Bit Avoid When Drilling?
① Avoid punching at the inlet of the pipeline: In some places where there are no switches, it is possible to roughly draw the dense areas of the pipeline through the entrance of the pipeline, and try to avoid drilling at positions that appear particularly cumbersome for pipeline laying. ② Avoid punching at corners:
How to choose a drill bit that can match the drilling?
The selection of tools and drill bits must match the material of the tiles and the size of the holes. If it is a floor tile or a full tile, an electric hammer cannot be used, and a glass drill bit should be used for the drill bit. The correct operation method should be: First, use a hand electric dril
How to Choose the Appropriate Drilling Position
Avoid ceramic tile corners and at the intersection of ceramic tiles When measuring, if the punching position is at the corner of the ceramic tile, it is necessary to plan the installation position again to avoid the corner position of the ceramic tile. When applying tiles at the corners, less cement is used, resulting in less than 1/2 of the actual stress positio
The position should be precise Before drilling, it is necessary to use a marker to mark the position of the hole, and the drill bit should accurately and steadily drill the ceramic tile along the hole position. The angle should be perpendicular When drilling, try to m
How to Use an Impact Drill Bit?
1. Before drilling, mark the position of the hole on the wall with a pencil or chalk, and punch the center of the hole with a center punch; 2. Then select a straight, sharp, non-destructive impact drill bit with the same diameter as the hole; 3. Open the card head, insert the drill bit to the bottom, and tighten the card head with the card head key. Grasp the impact drill with bo
Some Knowledge about the Spiral Angle of Drill Bits
The inclination angle of the spiral groove relative to the axis of the drill bit is equivalent to the rake angle of the turning tool. The front angle of the drill bit varies with the position of the cutting edge, with the outer circumference being the largest and the smaller towards the center. At the transverse edge, a negative rake angle is formed, resulting in crushing and crushing of the workpiece material. The large helix angle increases the front angle
