Material and durability Made from hardness steel for wear resistance and long service life. Engineered for hardness and speed cutting so the tool maintains edge retention under demanding use. Improved cutting performance Fully ground spiral flutes enable large chip evacuation and reduce clogging. Smooth chip removal prevents the drill from sticking, reducing downtime and increasing throughput. Reliable packaging and protection Each step drill is individually sealed in plastic packaging to protect against damage in transit and storage, ensuring the tool arrives ready to use. Broad machine compatibility Designed for use with CNC machines, machining centers, engraving machines, and other speed CNC milling equipment. Suitable for a range of speed milling and drilling workflows. Why choose this step drill Reduces cycle time by preventing chip buildup and sticking during continuous or speed operations. Extends tooling life with wearresistant steel construction, lowering replacement frequency. Arrives protected and ready to install, minimizing the risk of receiving damaged tools. Typical applications Metal fabrication: drilling stepped holes in stainless steel or alloy panels for brackets, chassis, and enclosure assembly. Electrical and control enclosures: creating accurate stepped openings in aluminum or thingauge sheet for connectors, switches, and cable glands. Precision CNC work: producing stepped holes and countersinks on machining centers and engraving machines for fixtures and prototyping.
