Freud DSD0750S09 Step Drill Bit 9 Step 3/4 Inch

Product Description

The FREUD DSD0750S09 is a 9-step step drill bit engineered for fast, accurate hole cutting in thin metals, PVC, and other plastic materials. It covers a drilling range of 3/8 inch to 3/4 inch and features a 132-degree split point tip that starts on contact without walking, reducing the need for a center punch. The 1/4 inch hex shank is compatible with both standard drills and impact drivers. Built with a precision-ground step profile, this bit is rated for up to 4x longer life and 2x faster cuts compared to standard step bits. It is suited for electricians, plumbers, HVAC technicians, and other trade professionals who regularly punch holes in sheet metal panels, electrical boxes, and plastic enclosures.

The DSD0750S09 is designed for use in residential and light commercial applications where clean, stepped holes are required in thin-gauge sheet metal, conduit knockouts, PVC panels, and similar materials. The 1/4 inch hex shank allows direct chucking into impact drivers, making it practical for field work where cordless tool efficiency matters. In high-speed mode, the bit supports up to 75 percent more holes per battery charge compared to standard step bits, which is a measurable advantage during rough-in work when multiple penetrations are required in a single run.

Installation Notes

Installation is typically performed by electricians, HVAC technicians, or plumbers during rough-in and panel work. Secure the workpiece before drilling and use appropriate eye protection when cutting metal or plastic. Verify that the drill or impact driver is set to the correct speed mode for the material being cut. Inspect the bit for wear at each step after heavy use and replace if the cutting edges show visible dulling or chipping.
