Question 1: What kind of drill bit can be used to drill brass high-speed steel? However, it is easy to prick the knife, so it is best to reduce the rake angle at the outer edge of the bit, that is, to grind a small plane, and at the same time narrow the edge of the bit to improve the smoothness of the hole.

Question 2: What kind of drill can be used for copper?

Common drill types are twist drill, flat drill, center drill, deep hole drill and casing drill. Although reamers and countersinks cannot drill holes in solid materials, they are customarily classified as drill bits.

1, twist drill: it is a tool to drill the round hole of the workpiece through its rotary cutting relative to the fixed shaft. It is named because its chip groove is spiral and looks like a twist.

2. Flat drill: the cutting part of the flat drill is ground into a flat body, and the main cutting edge grinds the front corner and the back corner to form a cross edge; The secondary cutting edge grinds the rake angle and secondary deflection angle and controls the drilling diameter.

3. Deep hole drill: a drill bit specially used for processing deep holes.

4. Reaming drill: Reaming drill is generally used for semi-finishing or finishing of holes, and pretreatment before reaming or grinding or enlarging blank holes. It has 3 ~ 4 cutting edges, no transverse edge, little change of rake angle and rake angle along the cutting edge, good guiding effect during machining, small axial resistance and better cutting conditions than drilling.

5. Countersunk drilling: that is, countersunk drilling. A drill bit used to drill a conical countersink, also called a countersink drill. Other names (chamfering cutter, chamfering device) English name countersunk drill. 6. Center drill: used for prefabrication and accurate positioning of hole processing, guiding twist drill to hole processing and reducing errors. The center drill is used to process the center hole of the end face of the shaft and other parts.

7. Hollow drill: also known as hollow drill, steel plate drill and hole drill, its standard name is multi-edge steel plate drill. It adopts the form of multi-blade annular cutting, and only the annular part of the outer diameter of the hole is cut with the drill bit, and the middle part is not cut, which greatly improves the drilling efficiency. Combined with magnetic drill, it can realize drilling operation in the field at any time, which is more efficient and lighter than ordinary twist drill. Borehole diameters range from12mm to150mm, and depths are 25mm, 35mm, 50mm, 75mm,100mm,150mm, 200mm, etc.

Question 3: Can an electric drill drill copper? Yes, but please note:

1, copper is very sticky, so in the process of drilling, the feed speed should not be fast, the feed speed should not be too high, and the drill bit must be sharp (the rake angle should be large).

2. Copper has a large thermal expansion coefficient, and some of it will melt when drilling, but it will recombine after cooling, so the accuracy is difficult to control.

Question 4: What kind of drill bit is used for drilling red copper? Titanium plated twist drills and flat drills.

Question 5: What kind of drill bit should be used to drill copper? Titanium-plated twist drill and flat drill.

Question 6: Can a pure copper drill be used? Carbide drills should be able to drill holes.

Question 7: It is not difficult to choose copper bit for turning, and cemented carbide can basically meet it.

Question 8: this product is made of copper ... what kind of drill is better for drilling ... the great gods who know it say thank you for me. I have a workpiece hole as thin as 100 minutes, and it is best to use a thin-walled drill, that is, a drill with a self-centering drill tip. Need?

Question 9: What kind of drill can be made by drilling a hole in a copper bar, so as to use an abrasive tool combined with diamond or diamond powder?

But it's not like hitting a small stone.

Use a small electric drill! The diameter is measured in centimeters and millimeters.

Punching holes in small stones is common in jewelry processing. In ancient times, it was carried out through a jade water stool. At present, the function of fast drilling is realized by motor and small drill.

Question 10: What parameters are given when drilling with 1.5 bit when machining red copper in machining center? The capacity of copper is the same as that of aluminum, but it is harder than aluminum. First of all, the quality of the drill bit is good, the revolution is above 5000, the Q value is below 2mm, and the F500.
