Hertel C.E96.S8 Reduced Shank Drill Bit Set 8 Pc

Product Description

The HERTEL C.E96.S8 is an 8-piece reduced shank drill bit set designed for drilling large-diameter holes with a standard 1/2-inch shank on conventional drill presses and hand drills. Bit sizes range from 9/16 inch to 1 inch in 1/16-inch step increments, covering the most common large-bore applications in metal fabrication, mechanical contracting, and industrial maintenance. All bits are manufactured from high-speed steel (HSS) with an oxide finish for improved heat resistance and lubricity during cutting. The 118-degree standard point angle suits general-purpose drilling in mild steel, aluminum, and similar materials.

This set is suited for trade professionals and production shops that require a range of large-diameter bits without swapping to morse taper tooling. The reduced 1/2-inch shank allows use in standard three-jaw chucks, making these bits practical on drill presses and heavy-duty portable drills. Typical applications include structural steel work, HVAC bracket fabrication, conduit knockout drilling, and plumbing rough-in work where holes between 9/16 inch and 1 inch are required in metal or similar substrates.

Installation Notes

Installation and use should be performed by a qualified machinist, millwright, or trade professional familiar with large-diameter drilling operations. Always secure the workpiece firmly before drilling and reduce feed pressure as the bit breaks through to prevent grabbing. Use cutting fluid on ferrous materials to extend bit life and reduce heat buildup. Inspect each bit for chipping or wear before use and replace any bit that shows signs of damage.
