FAQ

Cobalt containing special stainless steel drill bit, 4mm angle, do not move?

No matter what drill, the head must be sharpened! The small drill can be struck because the front edge is well sharpened! And 8.5 of the drill bit can not drill through, because the drilling side of the two cutting edges did not grind out (front angle is lower than the back angle, resulting in non cutting! To grind to the rear corner, lower than the front corner!!!!!!!!. When the drill bit blade grinding, drilling 4mm angle, is very fast, also don't add coolant! (head color change, drill when there is a cry, two sides do not chip out, all the drill bit did not wear well), grinding drill bit is a learning, learning is not difficult. Learn to grind the drill bit and drill around with the 10mm to see the edges.

What bits of percussion drills are made of?

Purpose: hard alloy is widely used as a tool material, such as turning, milling, planing, drilling, boring, used for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone and steel, can also be used for cutting steel, stainless steel, high manganese steel, tool steel and other hard processing materials.

Do you have any special drill for aluminum alloy?

Twist drill grinding points need to pay attention to, first of all to ensure that the correct grinding angle. The two main cutting edge length and angle to symmetry, there is a formula: drill blade surface on the wheel. The drill shaft out of the front, left oblique angle. From the back edge grinding angle, swing up and down the tail don't tilt.If necessary, the cross edge can be repaired, and the trimming edge and the chip separation groove can be polished, and the blade should be cooled during the grinding process to avoid the edge annealing.

Why not hammer drill iron

Electric hammer drill (electric hammer drill), is the "two function drill" and "hammer" handheld electric tool, "rotary cutting drill", with the impact of the impact mechanism of driving impact drill bit, drill driven in rotation at the same time, there is a direction perpendicular to the rotation of the rotary drill the reciprocating motion of the hammer. For concrete, brick, tile, marble and other materials drilling. "Hammer" to drive the impact force of drill rod, used for concrete, bricks and other materials on the slotting, holes or broken concrete etc..

How do you get yellow on the surface of the drill bit?

The Yellow above the drill is not baked. It is a kind of coating which is evaporated and ionized by the titanium metal in the high temperature and high vacuum environment. At the same time, the coating is added to the metal surface after the reaction of the reaction gas. It is also called PVD coating.

With what drilling steel

Tungsten steel (hard alloy) with high hardness, strength and toughness, good wear resistance, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at a temperature of 500 DEG C also remained unchanged, at 1000 degrees C still have high hardness.

What do you mean by 5 times diameter drill?

The length of the chip slot is 5 times the diameter of the drill bit.5 times a bit is the drill depth that can reach 5 times the diameter of the drill. For example, a drill with a diameter of 10 can process 50 deep holes.

CNC machine tools I use 6.5 bit drilling out is 6.7, what method can be solved?

Finish with 6 and take 6.5 of the drill. Or trim the bit edge of the drill bit slightly
