They are an essential tool for construction, manufacturing, DIY projects, and more.Drill bits including HSS twist drill bit, with straight shank and hex shank, wood drill bits, and construction drill bits for different working application sites.Drill bits come in sizes ranging from small 1mm bits to large 50mm bits and above. The material, coating, and design affect their performance and applications. Understanding drill bit types and using the correct one is key to efficient drilling. Regular maintenance and replacement of worn bits are also important. Overall, drill bits are indispensable tools that provide the openings and holes required in all kinds of DIY, construction, and manufacturing work.Recommended Cutting Parameter Table for Processing Various Materials Using High-Speed Steel Plate DrillsMaterialCutting speed m/minFeed rate mm/rCoolant ml/minLow-carbon steel18-250.08-0.13≥40Medium-carbon steel15-230.08-0.13≥40High-carbon steel13-200.07-0.13≥40Structural alloy steel14-220.07-0.13≥40Tool steel11-160.07-0.13≥60Stainless steel9-150.06-0.11≥200Aluminium60-800.2-0.25≥80Cast iron20-400.1-0.16No compressed air cooling requiredBronze21-300.12-0.18No compressed air cooling requiredBrass35-500.15-0.21≥40Titanium alloy4-100.07-0.13≥200Manganese alloy10-180.05-0.1≥400Superalloy8-200.05-0.1≥400 Recommended Cutting Parameter Table for Processing Various Materials Using Carbide Steel Plate DrillsMaterialCutting speed m/minFeed rate mm/rCoolant ml/minLow-carbon steel38-500.07-0.12≥40Medium-carbon steel35-450.07-0.12≥40High-carbon steel35-450.07-0.12≥40Structural alloy steel30-400.07-0.13≥40Tool steel25-400.07-0.13≥60Stainless steel12-210.08-0.12≥200Aluminium80-1200.15-0.2≥80Cast iron55-750,1-0.15No compressed air cooling requiredBronze48-600.1-0.15No compressed air cooling requiredBrass30-420.1-0.15≥40Titanium alloy6-150.1-0.13≥200Manganese alloy15-280.07-0.1≥400Superalloy13-240.07-0.1≥400 Main Fastener CoatingTypesApplicationSpray Test HoursCharacteristicsMirror Nickel-platingALL Metal72HoursStableExcellent polishing performanceImprove Wear resistanceWide range of applicationsMatt Nickel-platingALL Metal72HoursBlack Nickel-platingALL Metal48HoursHigh absorption rate of solar energyUsed in solar collector panels.Manganese PhosphateALL Metal72HoursEnhanced resistanceSand BlastALL Metal-Remove paint, rust, and residue scratches or casting marksElectrophoresisALL Metal1000HoursMaintain metallic lusterAnti-corrosion propertiesColor ElectroplatingALL Metal96HoursImprove mental strength Prevent metal oxidation Steel Material Chemical CompositionTypesCSiVCrMnNiMoCharacteristicCR-MO0.18-0.230.15-0.35-0.40-0.600.90-1.20-0.13-0.2041xx-series SAE steel gradesExcellent strength-to-weight ratioStronger and harderNot easily weldedCRV0.50.30.180.80-1.100.70-0.90--6000-series SAE steel gradesSuitable for hardeningResist abrasion, oxidation, and corrosionImprove material elasticityS20.40-0.550.90-1.20<0.50-0.30-0.50<0.300.30-0.60One of seven types of shock-resisting steels under the AISI ClassificationHigh strengthHigh toughnessWear resistanceHigh hardnessResistance to shock loading45#0.42-0.050.17-0.37-≤0.250.50-0.80≤0.25-Compared with A3, it has higher strength and resistance to deformation.A30.95-1.050.10-0.500.15-0.504.75-5.500.40-1.00-0.90-1.40High-quality high carbon alloy tool steel Product Application Company ProfileQuality ControlCertificationsFAQ
