A flat drill is a woodworking tool. Flat drill bits are made of a very hard alloy. The cutting part of the woodworking flat drill is ground into a flat body, and the main cutting edge is ground to sharp angles and relief angles to form a cross edge; the secondary cutting edge is ground to grind the relief angle and secondary deflection angle and control the drilling diameter.

In short, the grinding process of hard alloy saw blades is different from that of ordinary circular saw blades. When the grinding rate is high, the grinding heat is high, which not only causes cracks in the hard alloy, but also leads to poor grinding quality.
Before grinding, the resin, debris and other debris attached to the saw blade must be removed. When grinding, the original geometric design angle of the saw blade should be strictly followed to avoid damage to the tool due to improper grinding. After polishing, it can only be put into use after passing the inspection to avoid personal injury.
When grinding a chisel edge with a small diameter drill, it is easy to control the width and symmetry of the chisel edge from the outside of the side and then move to the corner of the grinding wheel. Controlling the amount of grinding is not easy. For large-diameter drill bits, the chisel edge can be shortened directly with the grinding wheel fillet.

Alloy saw blades are a type of cutting tool, mainly used for sawing wood, aluminum alloy, iron, steel and other materials. It is mainly composed of a saw blade and an alloy cutter head, with various tooth shapes and relatively complex grinding. Many users report that the alloy saw blade is not sharp after polishing and is not easy to use. How should alloy saw blades be sharpened?
The construction of a long spiral drilling rig should select the drill bit based on the geological conditions on site.
The serration of the hard alloy blade should be higher than the back of the saw body, usually 0.2 to 0.3mm higher. Grind the front radial trimming tool behind the teeth of the hacksaw blade body. Diamond grinding wheels cannot be used for the steel tooth back of grinding tools, but rather silicon carbide or corundum grinding wheels.
The louver wheel, also known as the 100-page wheel, is a simplified version of the thousand-blade wheel. It is commonly used in automatic, electric, and manual grinding machines as well as polishing machines for grinding and polishing tasks. It falls under the category of industrial consumables.
