These simple tools allow you to extend the reach of your drill so you can drill holes in hard-to-access areas.Bit extension bars are metal rods that attach between your drill chuck and drill bit. They come in varying lengths, usually between 3 inches and 18 inches long. The most common sizes are 6 inches, 12 inches, and 18 inches.Extension bars are made from durable chrome vanadium steel or carbon steel. They have a male hex shank on one end that fits into your drill chuck, and a female hex socket on the other end to fit your drill bit. Some extension bars have male and female hex ends so you can connect multiple bars together for even longer reach.When using a bit extension bar, it's important to apply firm pressure and drill straight. The longer the extension, the more chance it has of bending or whipping around if you apply force at an angle. Start drilling slowly and adjust your pressure as needed.Extension bars are useful for drilling holes in ceilings, floors, decks, cabinets, and any other hard-to-access area. They allow you to avoid using a ladder to get your drill into tight spaces. Many auto mechanics use extension bars to reach engine parts without removing the entire engine.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 steelProduct Application Company ProfileQuality ControlCertificationsFAQ
