- Q: Types of impact drills
- There are two types of drill hole two groove round handle (usually produced abroad and anti hammer production abroad is used), four hole square shank (general domestic production of electric hammer used) and five bit six bit long pit, angle etc.. Hope to be of help to you.
- Q: What drills are used in stainless steel drilling?
- Stainless steel cutting drill martensitic stainless steel 2Crl3, just wear E-E chipbreaker; while drilling of lCrl8Ni9Ti austenitic stainless steel, but also need additional A-A chipbreaker.The characteristics of S type carbide drill is: chisel edge can reduce the axial force of 50%; a former angle is positive, sharp edge; web thickness increases, increase the drill rigidity; two jet cutting fluid hole; arc cutting edge and the chip distribution is reasonable, easy cutting into pieces. In order to facilitate discharge.The characteristics of transposition of cemented carbide drill for shallow holes is equipped with two front end of the drill bit is asymmetric convex triangular blades, different parts of the chip removal hole, automatic centering, straight hole, and the cutting length is short; blade rake face is provided with a plurality of pit groove cutting, good performance especially reliable chip breaking, the chip is consistent with the broken chip cooling; the cutting fluid is directly sprayed to drilling surface, improve the cooling effect, chip very smooth; especially according to the hard alloy blade with different grades of workpiece materials, cutting speed is 80 ~ 120m/min, drilling is very brisk.
- Q: Tap with 5 taps. How many drills are drilled?
- Calculation formula:The workpiece is a brittle material (cast iron, bronze, etc.): the bore diameter is D=d- (1.04 to 1.08) tThe workpiece is made of plastic material (steel, copper, etc.): bore diameter is D=d-tD: nominal diameter of thread, t: pitch, unit: mm
- Q: What is the difference between steel and high-speed steel?
- Tungsten is a kind of high speed steel was non alloy steel containing tungsten before, now use less, there are people on the use of power tools. Before the steel generally used for ordinary tool making hand taps, drills, saws and cutting speed is relatively low, the hardness is about 60~63HRC. High speed tool steel is now divided into low alloy, high performance and other types, widely used in the manufacture of various cutting tools.
- Q: What bits of percussion drills are made of?
- Features: 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.
- Q: What size drills and taps are required for drilling M10's internal threads?
- M10*1.5 (not considering tap tap for precision thread); if M10*1.25, with Phi 8.7 bit; M10*1.25 (without considering precision tap tap thread); if it is M10*1, with 9 bit;
- Q: What drill is used for punching aluminum parts?
- Aluminum alloy, copper, stainless steel, these materials are not high hardness, aluminum alloy, copper soft, frequent drilling process, it is easy to have cutting, there will be a lot of burrs, aluminum alloy special drill.
- Q: What kind of steel do you need to drill?!
- Some use ion implantation technology to inject titanium, nitrogen and carbon into the substrate at a certain depth, which not only improves the hardness and strength, but also makes them move when the drill is regrinding. Also, a diamond film is formed at the top of the drill bit by physical means, which greatly improves the hardness and wear resistance of the drill bit. The hardness and strength of cemented carbide are not only related to the ratio of tungsten carbide to cobalt, but also to the particle of powder.
- Q: An expansion screw with a diameter of 20. How much impact bit do you need to use?
- The table above is the reference value of the match;2, the specific adaptation, also need to be flexible according to the actual situation, if the fixed place expansion screw is loose, need to be reduced if the fixed impact drill specifications; expansion screws tight place, according to the above table match.
- Q: M2.5 hit the bottom teeth with much bit
- Then, the chip 2.5-0.45=2.05 is used to tap bottom drill bit drilling. If it is an extrusion tap, the formula is 2.5-0.45/2=2.275's drill.
