I had to buy the Drill Doctor. **Q: will this sharpen drill bits with a hex attached, similar to the Milwaukee Shockwave?** A: No. This sharpening attachment is designed for bits that have a uniform diameter. If you look closely you will see that the bit rests in a V-shaped holder which sets the correct angle. Any attachment to bit would "cock" the bit and make it impossible to get a correct angle. **Q: Can this be used with a belt sander?** A: Sure. It's all in how you mount it. A sanding belt will sharpen steel bits. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice Product *by J***. on 18 February 2021* Nice product ### ⭐⭐⭐ Drill grinding *by D***. on 27 June 2021* The screws not tighten properly ### ⭐⭐⭐⭐⭐ Good *by N***D on 6 November 2019* Useful ## Frequently Bought Together - General Tools Drill Grinding Attachment #825 - Drill Accessories - For use with ANSI, OSHA, and UL - General Tools Pocket-Sized 6-In-1 Multi Use Ruler and Gauge #16ME with 4-Inch Ruler and Etched Graduations in 64ths of an Inch and Millimeters - Norton Abrasives Dressing Tool Stick, Grinding Wheel Tool for maximizing Grinding Wheel Performance --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/245195802-instruments-825-drill-grinding-attachment](https://www.desertcart.co.uk/products/245195802-instruments-825-drill-grinding-attachment) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-22*
