A PDC bit is a tool used to drill through or blind holes in solid materials and enlarge existing holes. Commonly used drill bits are twist drill, plane drill, center drill, deep hole drill and sleeve drill. Reamers and countersunk drills are generally classified as drill bits, although they cannot drill into solid materials. High-speed steel hollow drill bit, also known as coring drill bit or hole opener, drill bit classification: high-speed steel drill bit, hard alloy drill bit, tungsten steel drill bit; Cutting depth: 35MM,50MM,100M; Applicable drilling: imported magnetic drill, magnetic drill, domestic magnetic drill, magnetic drill, magnet drill, steel plate drill, magnetic drill, machine tool, bench drill, etc. Diameter
PDC BitsIt is a tool used to drill through or blind holes in solid materials and enlarge existing holes. Commonly used drill bits are twist drill, plane drill, center drill, deep hole drill and sleeve drill. Reamers and countersunk drills are generally classified as drill bits, although they cannot drill into solid materials.
High-speed steel hollow drill bit, also known as coring drill bit or hole opener, drill bit classification: high-speed steel drill bit, hard alloy drill bit, tungsten steel drill bit; Cutting depth: 35MM,50MM,100M; Applicable drilling: imported magnetic drill, magnetic drill, domestic magnetic drill, magnetic drill, magnet drill, steel plate drill, magnetic drill, machine tool, bench drill, etc. Diameter: 12MM to 100MM; The main materials of PDC drill bits are diamond compact, powder metallurgy, and cemented carbide.
The axis of the PDC bit shall be at an angle of 60 ° to the grinding wheel face. This angle is the rake angle of the drill bit. At this time, the angle is wrong and will directly affect the size of the drill bit and the shape of the main cutting edge and the lateral bevel. This refers to the positional relationship between the main axis of the drill and the grinding wheel surface. It is possible to take 60 °, and this angle is usually more accurate. Here, pay attention to the relative horizontal position and angular position of the drill bit before grinding. Both should be considered as a whole, instead of balancing the edge and ignoring the angle, or balancing the angle without ignoring the edge.
The greater the length to diameter ratio of the PDC bit, the greater the slope of the bend. By reducing the aspect ratio, the deflection force can be reduced, thereby avoiding bit interruption and increase in aperture error. Deeper holes require a bit gauge with a larger aspect ratio. Typically, the hole depth is greater than 3 times the "deep hole" diameter, and the hole depth for micro-drilling is typically greater than this limit.
Hammer drill specifications: 6mm,8 mmx110mm; 8mm x 160mm; 8mm, 10mm, 12mm x 210mm, 10mm, 12mm, 16mm, 20mm x 450mm.
The main body of the electric hammer drill is made of high-quality alloy steel, and the cutting head is welded with cemented carbide. It is suitable for drilling holes in hard building materials such as concrete and bricks. It is widely used in construction, installation industry in high efficiency punching tool.

A. Classification of PDC bits by construction
(1) Integral drill bit: drill bit, drill body anddrill pipeare made of the same material.
(2) The end welding drill bit, the top of which is welded with cemented carbide.
B.PDC bits are classified by bit
(1) Straight shank drill bits, all drill bits with a drill diameter of less than 13.0mm use straight shank.
(2) Taper shank drill: the shank of the drill is tapered, and the general taper is Morse taper.
C. Classification of PDC bits by use
(1) Center drill: Generally used for drilling the center point before drilling. The front cone has 60 °,75 °,90 °, etc. In order to use the tailstock support during the lathe operation, the tool holder should use the 60 ° center drill and the lathe tailstock center 60 ° together.
(2) Twist drill: one of the most widely used drill bits in industrial manufacturing.
(3) Superhard drill bit: The front end or all of the drill bit is the material of the superhard alloy cutting tool, which is used to drill the processing material.
(4) Oil hole drill bit: There are two small holes on the main body of the drill bit, and the cutting agent reaches the cutting edge through these small holes to take away heat and chips. When the drill bit is stationary, the general working rotation of the drill bit.
(5) Deep hole drill: It was originally used to drill gun barrels and stone-covered pipes, also known as gun barrel drill. A deep hole drill is a straight groove in which a strong part of the 1/4 is cut away in a round tube to produce a cutting edge.
(6) Reamer: For mass production, the front end is the reamer and the rear end is the reamer. The diameter of the drill and the diameter of the reamer differ only from the edge of the reamer.
(7) Taper drill: A cone drill can be used when processing the mold feed port.
(8) Cylindrical drill: We call it a countersunk milling cutter. At the forward end of the bit there is a small diameter member called a tracking rod.
(9) Cone hole drill: It is used to drill conical holes, and its rake angle is 90 °,60 °, etc. We use chamfered cutter to drill conical holes.
