Q: What is a square hole drill and can be machined square hole?: The three vertices of an equilateral triangle as the center, edge radius at the apex on the side arc, get leelo triangle. As it is easy to prove that the triangle leelo properties, its width is equal to the structural length of the equilateral triangle. The length of the triangle leelo width within the square rotates, each corner of the path traversed basically is a square.

Q: Can HSS drill bits be drilled into stainless steel?: No, we should use alloy drill bit, drill vertex angle to 135 degrees, you can use the drill grinding machine repair grinding, our company is using Dongguan Muller machine drill grinding machine, grinding effect is good.

Q: Angle action and characteristics of standard twist drill: Front angle gamma Om (since the front surface of the twist drill is a spiral surface, the front angles of the points on the main cutting edge are different. From the outside, the center angle decreases gradually. The rake angle at the nose point is about 30 degrees, and about -30 degrees near the cross edge. The front angle on the cross edge is -50 degrees to -60 degrees.

At present, the coated carbide, metal ceramic, polycrystalline boron nitride (CBN), and polycrystalline diamond (PCD) material blades have been applied. The special shape of these advanced materials, the blade of the surface of the special coating attached to the process, can withstand mechanical impact and wear when the heat generated. However, the use of these blades requires additional external conditions, one of which is the close coordination of experienced tool suppliers.

Q: What are the main points of drill grinding?: Grind back from the edge of the blade. When the blade is in contact with the grinding wheel, it should be drawn back from the main cutting edge, that is, contact the grinding wheel from the edge of the drill bit and then slowly grind down the whole flank. Gently contact wheel bit penetration, advanced for less grinding, and observe the uniformity of discharge, timely adjustment of the size of the pressure on the hand, but also pay attention to the drill bit cooling, can not be allowed to wear too much, causing the edge to edge discoloration, annealing. When the blade temperature is high, the drill bit should be cooled in time.

Q: How big is the smallest bit?: Foreign trade HSS full grinding high speed steel straight shank twist drill, drill aluminum iron special twist drill / woodworking drill bit, relevant parameters:Model: YD0.5--14mm;Straight shank twist drill;Material: high speed steel;Blade diameter: manifold;Machine tools, tools, drills.
