Replaced couple of the adjustment screws with hand screw adjusters, as this makes setting different drill size bits much quicker and more accurate. Once set up properly to grindstone it works very well. Take your time getting the angles right and practice with a couple of old drills and results will be good. Did a lot of blunt drills, which now cut really well, set the cut angle to shallow cut for hard metals, excellent results through thick steel. Review: Drills now nice and sharp - Does a good job of grinding drills with drilled holes on size. Requires a good set up with attachment square to grinding wheel ## Features - The General Tools and Instruments 825 Drill Grinding Attachment extends the life of your drill bits by sharpening them back to factory tolerances - The angle adjustment gauge allows you to match the point angle of nearly any bit, and even works on countersinks - Designed with a pivoting neck for simple grinding of both sides of the bit - The Drill Grinding Attachment is intended for use with ANSI, OSHA and UL approved standard electric bench grinders or surface grinders - Perfect for both workshop and home use ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0002YOQ8Q | | Best Sellers Rank | 393,924 in DIY & Tools ( See Top 100 in DIY & Tools ) 3,253 in Drill Bit Sets | | Brand | General Tools | | Country Of Origin | Taiwan | | Customer Reviews | 4.3 out of 5 stars 1,275 Reviews | | Cutting Angle String | 118 Degrees | | Cutting angle string | 118 Degrees | | Finish Types | Silver | | Finish type | Silver | | Global Trade Identification Number | 00038728240705 | | Item Dimensions | 12.5 x 12.5 x 18.7 centimetres | | Item Weight | 0.02 Pounds | | Item dimensions L x W x H | 12.5 x 12.5 x 18.7 centimetres | | Manufacturer | General Tools & Instruments | | Material | High Carbon Steel Chrome Vanadium Steel | | Model Number | 825 | | Number of Flutes | 2 | | Shank Type | Straight | | Shank type | Straight | | Surface Recommendation | [All] | | Tool Flute Type | Spiral | | UPC | 021112055818 971483003188 031112658254 014444902103 038728240705 031113097717 787721337881 | | Unit Count | 1.0 count | ## Product Details - **Brand:** General Tools - **Cutting angle string:** 118 Degrees - **Finish type:** Silver - **Material:** High Carbon Steel Chrome Vanadium Steel - **Shank type:** Straight ## Images ![General Tools Drill Grinding Attachment (825) - Image 1](https://m.media-amazon.com/images/I/71kS31KptDL.jpg) ![General Tools Drill Grinding Attachment (825) - Image 2](https://m.media-amazon.com/images/I/71C4A7aJkML.jpg) ![General Tools Drill Grinding Attachment (825) - Image 3](https://m.media-amazon.com/images/I/817L0IMnRAL.jpg) ![General Tools Drill Grinding Attachment (825) - Image 4](https://m.media-amazon.com/images/I/71SXR7IfrwL.jpg) ![General Tools Drill Grinding Attachment (825) - Image 5](https://m.media-amazon.com/images/I/712jVqY2H+L.jpg) ## Questions & Answers **Q: What size drill bits can it sharpen up to** A: as wide as the clamp will let you which I found to be 15/16. with a little modification to tha clamp you could prob. go to 1 inch hope this helps **Q: can i use it on the left side on my bench grinder?** A: Yes it is bi-lateral but truly I have not had any success with consistent grinds on this. 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 ### ⭐⭐⭐⭐⭐ Bit sharpener *by J***S on 18 September 2025* Does a good job, but bit fiddly to set up.

I managed to find a video on U tube of a similar jig.Having followed that example iI find it is easier and better to grind the drills by hand without the jig ## 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.nz/products/49100763-general-tools-drill-grinding-attachment-825](https://www.desertcart.nz/products/49100763-general-tools-drill-grinding-attachment-825) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-04-23*
