3pc HSS Step Drill Bit Set Titanium Cone Bits for Metal Drilling - JEFSTPSHSS03

3pc HSS Step Drill Bit Set Titanium Cone Bits for Metal Drilling - JEFSTPSHSS03Description:JEFSTPSHSS03 3 Piece HSS Step Drill Bit Set is designed for professional automotive technicians, mechanics, and metal fabricators who require precision hole enlargement and clean drilling performance.This versatile set includes three commonly used step drill sizes:4–12mm4–20mm4–32mmStep drill bits are ideal for drilling multiple hole sizes with a single bit, making them particularly useful for automotive bodywork, electrical installations, bracket fabrication, and chassis modifications. The stepped cone design allows gradual hole enlargement while reducing the risk of metal tearing or distortion.Manufactured from high-speed steel (HSS) and finished with a titanium coating, these drill bits offer improved durability, heat resistance, and smoother cutting action. The coating reduces friction during drilling, helping to extend tool life when working on steel body panels, aluminium sheets, plastic trims, and thin metals commonly found in vehicle repairs.These step drills are suitable for use with standard electric drills and are ideal for:Automotive body panel modificationsInstalling wiring and grommetsSheet metal fabricationGarage repairs and restorationsElectrical conduit hole drillingSupplied in a sturdy metal storage case, the set ensures safe storage and easy transport within busy workshop environments.3 Piece Step Drill Set:Includes popular size ranges: 4–12mm, 4–20mm, and 4–32mm for versatile automotive applications.High Speed Steel Construction:Manufactured from durable HSS for strength, precision, and long service life.Titanium Coated Finish:Reduces friction, improves heat resistance, and extends cutting performance when drilling metal panels.Ideal for Automotive Metalwork:Perfect for drilling sheet steel, body panels, aluminium, and plastic components.Code: JEFSTPSHSS03:Supplied in a durable metal storage case for organised workshop use.
