Notice:
1. Type A central tungsten carbdie drill bits are a cutting tool and is mainly used for metal drilling. Users must reasonably select the type of central drill according to the hole type and ruler size of the parts to be processed
2. The hardness of Type A central tungsten carbdie drill bits is 62-64 degrees, which can be used to process steel parts and stainless steel
3. Before the tool is used, the anti rust grease must be cleaned to prevent chips from sticking to the blade and affecting the cutting performance
4. The surface of the workpiece to be machined shall be straight without sand holes or hard spots to avoid damage to the tool
5. Precautions: In case of any abnormal condition during processing, stop processing immediately, find out the cause before processing, and pay attention to the wear of the cutting edge for timely repair; Clean the oil stain on the surface of the tool after use and keep it properly
6. This product can be reground for use
Applications:
Our tungsten carbide drill bits could to be processed Alloy steel, Tool steel, carbon steel, stainless steel, Cast iron and Titanium alloy. Working material as following:
FAQ
Q1. Excessive aperture
Reasons: 1. The cemented carbide drill is not well clamped, and the runout of the spindle itself is too large
2. Asymmetrical sharp angle, excessive blade height difference, eccentric cross blade
Solution: 1. select high-quality tool handle and fixture, calibrate the spindle, and carefully measure and adjust each time the drill is clamped
2. Re sharpen and correct, and check the accuracy after sharpening
Q2. Poor consistency of aperture
Reasons: 1. Asymmetrical sharp angle, too large difference in blade height, eccentric transverse edge, and too much wear on edge surface
2. The cemented carbide drill bit is not properly clamped, the runout of the spindle itself is too large, and the workpiece is not firmly clamped
3. Excessive feed speed
4. Insufficient cutting fluid supply
Solution: 1. Re sharpen the drill and check the accuracy after sharpening
2. Select a good tool handle and fixture, calibrate the spindle, and carefully measure and adjust each time the drill is clamped
3. Reduce the feed speed of cemented carbide drill
4. Change the cutting fluid supply method and increase the flow).
Q3. Poor hole straightness and verticality
Reasons: 1. Excessive tool wear
2. Asymmetrical sharp angle, excessive blade height difference, eccentric cross blade
3. Insufficient rigidity
4. Uneven cutting plane
Solution: 1. Re sharpen
2. Re sharpen and correct, and check the accuracy after sharpening
3. Improve the rigidity of machine tools, jigs, cemented carbide drills, etc
4. Check the levelness of the pre machined surface
Q4. Poor hole location and poor consistency of center distance
Reasons: 1. The drill bit is not properly clamped, and the spindle itself has excessive runout
2. Deviation during cutting
3. Machine tool accuracy loss
4. The centering effect of cemented carbide bit is poor, and the cross edge is eccentric
Solution: 1. select a good tool handle and fixture, calibrate the spindle, and carefully measure and adjust each time the drill is clamped
2. Improve the rigidity of the cutter and machine tool, and the rigidity of the workpiece and fixture. Use the drill type with good cutting performance, and check the levelness of the cutting surface
3. Check the accuracy of the machine tool
4. Re sharpen the carbide bit, and check the accuracy after sharpening
