Habe jetzt 50 Bohrer aller Größen durch. Mit ein wenig Übung geht alles zwischen 5-10mm in ca. 30s pro Bohrer. Die kleinen brauchen etwas länger, hauptsächlich, um vor dem schärfen die Schneide auszurichten. Das ist etwas Fummelarbeit. Dauert halt dann 10s länger pro Bohrer. Das Schärfen selbst ist dann sowieso Sekundensache. Da das Gerät so gut funktioniert, würde ich fast sagen: Leute, investiert in nur einen guten Satz HSS-Bohrer und schärft die regelmäßig mit diesem Gerät nach, dann hat man die ein Leben lang. Review: Amazing little machine, well worth the money - I have purchased the MR-13B model. It is cheaper on desertcart than model A and it is better in my opinion. There are several YouTube videos, describing both models in detail. Somehow you led to believe that model A splits the point and model B just thins the web. This is not true. Model B in my opinion is an improvement over model A. It allows you to achieve a true split point and has several ways of doing it. I am not going to write about every detail, but will concentrate on staff, which is not well described and is important in my opinion. This little machine is well engineered and constructed. It weighs 17.7 lb with collets, chuck and grinding wheel. There is no plastic anywhere except some electrical parts. The power supply is 120 VAC, 60 Hz. The cable can be separated from the unit. Electric part is very simple - there are a power receptacle, switch, rectifier bridge and a 110 VDC motor. There is no other electronics in the unit, so it has to be reliable. All parts are mounted on a 7 mm thick steel plate. They are steel (no aluminum here), machined and ground where necessary. That is how you achieve the accuracy needed for drill sharpening. For sharpening you have to setup each drill in the setup station at the left side of the machine. You use a chuck and a collet of the appropriate size. The collets are standard ER20 for sizes above 5 mm. For smaller sizes the collets are modified to include an extended nose and relieved bore. Drills smaller than 4 mm are very difficult to setup properly in this station and I would recommend to do a visual setup or just grind them by hand. The chuck has 2 bearings to reduce the collet clamping torque Once your drill is setup in the chuck you move it to a sharpening station, where you sharpen both lips by rotating the chuck back and force. This station has a bearing as well for easy rotation. If you want to split the point after sharpening, move your chuck to the top station and again rotate the chuck left and right. This operation is adjustable for the depth and width of the cut. The produced split point looks somewhat different from factory drills, but works the same way. The difference is because this machine uses just one wheel for sharpening and point splitting. The finished drill has 4 distinct cutting edges, just like the factory split points. This machine comes with CBN and diamond wheels, model A includes only CBN wheel The wheel is steel with plated layer of CBN or diamond grit. On the attached pictures I show the diamond wheel. It is 3" in diameter, 10 mm wide and has approximately 1/2" bore. The wheel is clamped to the adapter, which is attached to the motor shaft by 3 set screws. I have only tried the CBN wheel for HSS drills. It cuts very aggressively, but leaves an acceptable finish for bigger drills. For small drills you better find a different way of sharpening. Overall my level of satisfaction with this machine is very high. I am getting good drill grinds and nice split points. But don't fool yourself into thinking that it will do the grinding for you. You need to know what a good grind looks like and adjust the machine accordingly. ## Features - High-precision Sharpening: VEVOR MR-13B drill bits sharpener excels at sharpening point angle and lip relief angle.

It can sharpen drills up to 3/4" quickly and consistently, which saves us time and keeps tooling in rotation. For a professional-grade sharpener, the price is very reasonable. It doesn’t do true split points, but it can modify them into web thinning, which works just as well in practice. Overall, it’s a cost-effective and dependable solution for keeping drills sharp in a production environment. ## Frequently Bought Together - VEVOR Drill Bits Sharpener, 3-13mm Drill Bits Grinder Sharpener, Lip Relief Angle & 95°-135° Point Angle Adjustable Drill Bit Re-Sharpener, Portable Sharpening Machine with 11 Collets, CBN & SDC Wheel - HARFINGTON Drill Bit Angle Gauges 60°-160° Drill Sharpening Gauge, Stainless Steel Angle Measuring Gage - Drill Point Sharpening Gage - Hints for hand grinding twist drills - Standard Inch Sizing --- ## 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.at/products/721009150-vevor-drill-bits-sharpener-3-13mm-end-mill-grinder-sharpener](https://www.desertcart.at/products/721009150-vevor-drill-bits-sharpener-3-13mm-end-mill-grinder-sharpener) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-07-09*
