RUKO Spiral Fluted Hss Step Set 3 Pieces 101026RO

RUKO Spiral Fluted HSS Step Drill Bits Set: Precision Drilling in Metal and PlasticsElevate your drilling capabilities with the RUKO Spiral Fluted HSS Step Drill Bits Set, the ultimate accessory for professionals demanding precision, efficiency, and superior performance. This 3-piece set is expertly engineered to handle a wide range of materials, making it an indispensable tool for electricians, plumbers, metalworkers, and industrial technicians. Designed for use with electric tools, this set excels in drilling clean, burr-free holes in sheet metal and other materials without the need for pre-drilling.Experience a new standard in drilling performance. The innovative combination of CBN-ground cutting edges and deep spiral grooves delivers exceptionally quiet operation and a remarkably high cutting rate. This advanced design significantly optimizes chip flow, a critical factor when working with various materials. Even long, non-breaking chips, which can clog and damage standard drill bits, are effortlessly and cleanly removed from the workpiece. This superior chip evacuation not only ensures a cleaner job but also actively protects the delicate cutting edges from premature wear, reducing the risk of edge buildup and cold weld marks that can compromise both the tool and the material.Crafted for versatility and durability, this HSS step drill bit set is your go-to solution for creating multiple hole sizes with a single tool, capable of producing diameters starting from 4 mm. The unique 3-way clamping surface on the shaft guarantees a secure, slip-free grip in any standard drill chuck, ensuring maximum torque transfer and operational safety. The conical shape of each step drill bit further enhances the user experience by making it significantly easier to withdraw the tool from the material after drilling is complete, saving time and preventing damage to the newly created hole. Whether you are working on a new installation or a repair job, this set provides the reliability and precision that define professional-grade work.CBN ground and spiral grooves ensure quiet operation and high cutting performance.Especially the chip flow is optimized, so even long, non-breaking chips are easily removed.Optimized chip flow protects cutting edges and reduces edge buildup and cold weld marks.The cone makes it easier to remove the tool from the material.Technical data:Number of cutting edges:2.Coating:uncoated.Shaft:3-way clamping surface.Cutting direction:cutting right.Material:HSS.Tolerance:working specification.Tip angle:118.Pitch angle:90.Application areas:Main application:Steel 900 N/mm², Aluminum, Brass, Plastics.Other applications:Bronze, Cast iron
