Drill Doctor 750X Drill Bit Sharpener, 3/32–3/4-Inch Capacity, Adjustable Angles

How it fits

Restore drill bits at the workbench instead of setting aside each dull bit for replacement. The Drill Doctor 750X sharpens standard twist and masonry bits from 3/32 to 3/4 inch, covering a broad range of common drilling tasks with one electric sharpener. Its adjustable point angle lets you set a bit between 115 and 140 degrees for the material and application.

That range makes the 750X useful for a home workshop or professional work area where bit sizes and jobs vary. Keep the sharpener close to the drill station, then use it when a bit needs attention. It handles carbide, cobalt, high-speed steel, black oxide, TiN-coated, and masonry bits, so you can work with several bit types using the same tool.

Benefits

The adjustable angle gives you a practical way to match the point geometry to the task, while the ability to sharpen or create split points adds flexibility for bit maintenance. A Push to Stop port helps prevent over-splitting during that process. The 3/4-inch chuck accommodates the sharpener’s stated bit-size range, including larger bits.

The included 180-grit diamond wheel is preinstalled, and the six-foot power cord supports placement near a suitable work area. A carrying and storage bag, wheel hub wrench, and chuck round out the stated package. Together, these details make it easier to keep the sharpener organized and ready for recurring bit-care tasks.

Buyers commonly describe the sharpener as effective and straightforward to use, including for larger bits. Some also find the process easier than using a bench grinder, making a dedicated sharpener an appealing approach when you want a repeatable way to restore drill points. Feedback on the instructions is mixed, so allow time to follow the sharpening process carefully when getting started.
