Ruko Hss-tin Step Drill Bits Set 3 Pieces. RUKO HSS-TiN Step Drill Bit Set - 3 Pieces for Precision Metal DrillingElevate your drilling capabilities with the professional-grade RUKO HSS-TiN Step Drill Bit Set. This comprehensive 3-piece set is meticulously engineered for professionals in electrical installation, sanitation, heating, automotive, and general engineering who demand unparalleled precision, efficiency, and durability. Designed to flawlessly drill clean, burr-free holes in a variety of materials, this set is your ultimate solution for versatile and high-performance work, especially in sheet metal applications.Unmatched Performance and LongevityExperience the superior cutting power and quiet operation that sets RUKO tools apart. The key to this set´s exceptional performance lies in its advanced design and material excellence.Ground and spiral CBN grooves ensure quiet operation and high cutting performance. This sophisticated flute geometry is engineered for optimal chip flow, so even long and non-breaking chips from tough materials are removed easily and efficiently. This superior chip management actively protects the cutting edges from damage, significantly reducing the occurrence of built-up edges and cold weld marks. The result is a cleaner cut, a smoother finish, and a dramatically extended tool life. Furthermore, the integrated cone on each bit makes it easier to withdraw the tool from the material after drilling, saving you time and effort on the job.Constructed from high-speed steel (HSS) and enhanced with a state-of-the-art TiN coating, these drill bits offer maximum hardness and wear resistance. The Titanium Nitride coating reduces friction, minimizes heat build-up, and allows for higher cutting speeds, ensuring you can work faster and longer. This 3-piece set is the ideal choice for any workshop or toolbox, providing a range of diameters starting from 4 mm to handle multiple hole sizes with a single tool.TECHNICAL DATA:Number of cutting edges: 2.TiN coating.Cutting direction: Cut to the right.Material: HSS.Tolerance: Specification of the work.Tip angle: 118°.Step angle: 90°.APPLICATION AREAS:Main application: Steel < 900 N/mm², Brass, Plastics.Other applications: Steel < 1100 N/mm², Stainless steel, Bronze, Cast iron.CONTENTS:This comprehensive set includes everything you need for a wide range of hole sizes, conveniently organized in a durable plastic case:1x Step drill bit 101050-9T HSS-TiN size 0/9 (Ø 4-12 mm).1x 101051T HSS-TiN step drill size 1 (Ø 4-20 mm).1x 101052T HSS-TiN step drill size 2 (Ø 4-30 mm).Plastic case. tradeinn Bricoinn
