1/2" Reduced Shank Drill Bit Collection (13mm-38mm), M2 HSS Black Oxide Twist Drills with 135° Tip, Compatible with Standard Chucks for Metal, Steel, Copper, Plastic & Wood Working,38mm,1/2"

M2 High-Speed Steel Reduced Shank Drill Bits 13mm to 38mm, 1/2" Shank with Nitriding Black Coating, 135° Split Point for Precision Drilling in Stainless Steel, Cast Iron, and Hard AlloysUpgrade your workshop capabilities with our premium Reduced Shank Drill Bits. Engineered for machinists, metalworkers, and serious DIY enthusiasts, these bits combine the robustness of M2 High-Speed Steel with a versatile 1/2" shank design. This unique construction allows you to drill large-diameter holes using standard drills equipped with 1/2" chucks, saving you the cost of specialized large-capacity equipment.Key Features & BenefitsSuperior M2 High-Speed Steel Construction: Crafted from industrial-grade M2 HSS, these drill bits offer exceptional hardness, thermal resistance, and wear resistance. They are specifically designed to tackle medium-to-high hardness metals without losing their sharp edge.Advanced Nitriding Black Finish: Each bit undergoes a specialized nitriding process to create a black oxide surface. This finish not only provides superior corrosion resistance but also reduces friction and heat buildup during drilling, significantly extending the tool's service life compared to standard uncoated bits.135° Split Point Geometry: Say goodbye to "walking" drills. The aggressive 135-degree split point tip ensures instant self-centering and penetration, even on hard or curved surfaces. This design enhances stability, reduces the risk of tip chipping, and delivers cleaner, more accurate holes with less downward pressure required.Universal 1/2" Reduced Shank: Available in a wide range of cutting diameters from 13mm to 38mm, each bit features a standardized 1/2" (12.7mm) shank. This ensures compatibility with most standard hand drills, drill presses, and magnetic base drills.Wide Range of ApplicationsWhether you are working in heavy fabrication, automotive repair, or general construction, this drill bit series is up to the task. It effortlessly penetrates:Hard Metals: Stainless Steel, Alloy Cast Iron, Carbon Steel, and Iron.Non-Ferrous Metals: Copper, Aluminum Alloys, and Brass.Other Materials: Hard plastics, composite materials, and wood.Pro Usage Tips for Best ResultsTo maximize accuracy and tool life, especially when drilling larger diameters:Pilot Hole Strategy: Always start with a smaller pilot hole when using large drill bits. This guides the larger bit, ensures perfect concentricity, and reduces the torque load on your drill motor.Coolant is Key: When drilling steel or stainless steel at high speeds, always use an appropriate cutting fluid or coolant. This dissipates heat, prevents the workpiece from work-hardening, and protects the HSS edge from premature wear.Speed & Feed: Use slower RPMs for harder materials and larger diameters, applying steady, firm pressure.Package Includes1 x Reduced Shank Drill Bit (Please select your required size between 13mm and 38mm)Shank Diameter: 1/2"Invest in tools that last. Choose our M2 Reduced Shank Drill Bits for precision, durability, and professional results every time.
