Freud DSD1125S17 Step Drill Bit 1-1/8 Inches Impact

Product Description

The FREUD DSD1125S17 is a 17-step step drill bit engineered for fast, accurate hole-cutting in thin metals, PVC, and other plastic materials. It covers a step range from 7/8 inches up to 1-1/8 inches. The split point tip is ground to 132 degrees, allowing the bit to start on point without wandering, which directly reduces drill-out and material distortion. The precision-ground steps reduce friction at each cutting edge, delivering up to 2x faster cuts compared to standard step bits. A 1/4-inch hex shank makes it compatible with both drills and impact drivers, including cordless tools running in high-speed mode.

This step drill bit is suited for electricians, HVAC technicians, plumbers, and general contractors who regularly drill knockout holes in sheet metal panels, electrical enclosures, junction boxes, conduit plates, and thin plastic materials. The impact-ready hex shank design means it transitions directly from a standard drill chuck to an impact driver collet without an adapter. In high-speed cordless mode, the design is rated for up to 75 percent more holes per battery charge compared to conventional step bits, making it a practical choice for production installs and service work where battery runtime matters.

Key Features

• 132-degree split point tip starts on contact, no center punch required on thin stock
• Precision grinding process on each step reduces wear and delivers up to 2x faster cuts
• Up to 4x longer life due to improved tip geometry and step profile durability
• 1/4-inch hex shank compatible with drills and impact drivers, corded or cordless
• Rated for up to 75 percent more holes per battery charge in high-speed cordless mode
• Cuts thin metals, PVC, and other plastic materials cleanly without step deformation

Compatibility

Designed for use with standard 1/4-inch hex chuck drills and impact drivers, both corded and cordless. Suitable for drilling in thin metals, PVC, and other plastic materials across a step range of 7/8 inches to 1-1/8 inches.

Installation Notes

Electricians and HVAC technicians should de-energize and lock out any panel or enclosure before drilling knockout holes. Secure the workpiece to prevent movement during drilling, as thin-gauge sheet metal can flex and grab the bit. Use high-speed mode on cordless tools to achieve rated cut efficiency. Inspect each step edge periodically during use and replace the bit if tip geometry shows visible wear.
