FAQ

What kind of drill is drilled by 40Cr heat treatment with hardness above 40 degrees?

The cost of the blade is relatively low, and the cost of cemented carbide blade is about 3% of the total processing cost,CBN blades are reinforced and guided, and they can prevent edges from chipping when machining materials with a hardness of more than 50RC.CBN blades make up 5-6%, so using cheap blades is a wrong way to save money. The use of advanced materials in the short term can recover the investment, and the waste rate is very low.

What's the difference between a drill bit and a tap?

A drill is a tool for drilling; a tap is a tool for cutting threads in a hole. That's the difference between them.

With what drilling steel

The general use of tungsten steel grinding head punch. The grinding head is a general name of a small belt grinding tool. It is applied to electric mills, suspension mills and hand drills. There are many types of ceramic grinding, rubber cement, diamond grinding head, grinding abrasive cloth etc..

What measures can be taken to prevent the bit from breaking?

I. to drill through, reduce the pressure. Slow down. Two. Drill the bit into a group

Drills, drills, heating drills, will they be annealed?

Drilling, drilling, heating, if the temperature is too high, will lead to accelerated drilling wear, and even annealing.The cutting heat in the cutting process due to friction deformation and cutting material separation and rub the cut material between, so drilling after jobs have hot feeling, but not as long as the cutting drill out of the blue or purple, generally does not cause a bit of annealing.

What's the diameter of the PT3/8 internal thread drill?

Dia 14.3-14.4.PT is the old standard, and it is also written as BSPT. Now the new standard is Rc, the same.

What causes the drill bit to break at the end of the hole?

Small bit not used high speed, with small feed amount.A small drill can withstand torque is small, the use of high speed with a small amount of feed, can reduce the small rotating cutting output, so as not to drill to bear large torque.

What steel blade drill bit, hardness above 60

A diamond bit is a drill bit for cutting edges. The drill bit is an integral bit, the whole drill bit has no moving parts, the structure is relatively simple, with high strength, high wear resistance and impact resistance, it is one of the three new drilling technologies in the world in 1980s. Field use shows that the diamond bit in the soft - hard strata drilling, have the advantages of high speed, more footage, long service life, stable operation, less accidents, downhole wellbore quality etc.. The diamond bit not only can be used for a long time, but also can be reused. The diamond bit recovered from the factory can be used almost as well as the diamond bit produced by the factory. It can save drilling cost in large amount.
