How to choose
Capacity and Bit Range
When selecting a drill bit sharpener, prioritize the size range compatible with your existing collection. Options like the VEVOR MR-13A+ and the MR-13A cover a 3-15mm range, while others like the drill-powered sharpener or the multipurpose orange model accommodate bits from 5/64 to 5/8 inches. Ensure the tool covers the specific diameters you use most frequently in your shop. Specialized tools, such as the woodworking square hole drill bit sharpener, are designed for mortise chisel bits up to 1/2 inch rather than standard twist bits. Matching the tool’s capacity to your inventory prevents the frustration of having a sharpener that cannot accept your specific drill bits.
Power Source and Portability
Consider whether you require a dedicated benchtop machine or a portable attachment. The VEVOR MR-13A+ and MR-13A are specialized grinding machines that utilize their own motors to achieve speeds like 5800RPM, making them suitable for stationary workshop or garage use. Conversely, the compact drill-powered sharpener is designed for high portability, fitting easily into toolboxes for use on jobsites. If you need to perform quick touch-ups away from a workbench, a portable, drill-powered device is the most convenient choice. However, if you require consistent, high-speed precision for frequent sharpening, a dedicated electric grinding machine offers a more robust and permanent solution.
Point Angle Adjustability
The precision of your sharpening depends heavily on the adjustable point angle features. Models like the VEVOR MR-13A+ and the MR-13A provide a range from 95° to 135°, allowing for versatility when sharpening different types of drill bits. This adjustability is critical for matching the manufacturer’s original geometry of the bit, ensuring it performs correctly in various materials. If your projects involve diverse materials requiring specific bit geometries, prioritize a model that allows for precise, wide-range point angle adjustments. Without this feature, you may struggle to restore a bit to its original cutting efficiency, potentially leading to poor hole quality or bit damage.
Included Accessories
Assess the included accessories to determine the overall value and capability of the sharpener. The MR-13A series models include 13 collets, which are essential for securing various bit sizes accurately during the grinding process. Other multipurpose sharpeners may include multiple grinding wheels, such as the unit with four wheels, to accommodate different bit types or maintenance tasks. Check whether the package includes everything necessary for immediate use or if you will need to purchase additional collets or wheels separately. Having a comprehensive set of collets or extra grinding wheels out of the box can save time and money, extending the utility of your sharpening investment.
Specialized vs. General Purpose
Identify whether you need to sharpen standard twist bits or specialized woodworking tools. A general-purpose sharpener, such as the multipurpose orange model or the 5/64-5/8 inch electric drill attachment, handles a broad variety of standard bits. However, if your work centers on joinery, a dedicated woodworking square hole drill bit sharpener is necessary to maintain mortise chisel bits. These specialized tools use specific grits, such as #220/600, to achieve the desired finish on chisel edges. Attempting to use a general-purpose grinder on specialized woodworking bits may not yield the required results, so align your purchase with the specific types of bits in your workshop.
Frequently asked questions
Which sharpener is best for a professional workshop?
For a professional workshop or garage environment, the VEVOR MR-13A+ is a strong candidate. It is a dedicated grinding machine featuring a 5800RPM motor and an adjustable 95° to 135° point angle.

This type of stationary machine offers the stability and precision often required for frequent, heavy-duty use compared to smaller, portable attachments.
Can I use these sharpeners for knife blades?
Some models are marketed with versatility in mind. For example, the multipurpose orange portable sharpener is described as including a knife sharpener tool feature. However, most specialized drill bit grinders, such as the MR-13A series, are strictly engineered for the geometry of drill bits and may not be suitable or safe for sharpening knife blades. Always verify the manufacturer’s intended use for each specific product before attempting to sharpen non-drill bit tools.
What is the benefit of a drill-powered sharpener?
A drill-powered sharpener, such as the model for 5/64–5/8 inch bits, offers the primary benefit of extreme portability. Because it does not require its own dedicated motor, it remains compact enough to fit easily into a standard toolbox. This makes it an ideal choice for jobsite use or for users who do not have the space for a benchtop grinding machine but still need to restore dull drill bits quickly.
Are collets necessary for sharpening drill bits?
Yes, collets are essential for many drill bit sharpening machines, such as the MR-13A series. They function by securely holding the drill bit in the exact position required for the grinding wheel to correctly restore the point angle. Without the appropriate collet for your specific bit size, the grinding process could be inaccurate or unsafe. These machines typically include a set of collets to cover the specified range of bit diameters.
How do I sharpen woodworking mortise chisel bits?
To sharpen woodworking mortise chisel bits, you should look for a specialized tool like the woodworking square hole drill bit sharpener. These are designed specifically for the unique geometry of mortise chisels and typically offer specific grit options, such as #220/600, to ensure the edges are properly maintained. You should avoid using standard twist bit grinders for this purpose, as they are not calibrated for the specific angles and shapes of square hole drill bits.
Bottom line
The VEVOR MR-13A+ stands out as the most robust choice for users seeking professional-grade performance and value for money. With a powerful 5800RPM motor, it provides the necessary speed for effective re-sharpening, while the 95°-135° adjustable point angle offers the precision required for diverse drilling tasks. Including 13 collets and a CBN wheel, it is a comprehensive solution for workshops managing a wide range of 3-15mm drill bits. Its 4.8-star rating reflects high user satisfaction regarding its build and capability. For those who prioritize a dedicated, high-speed machine over portable attachments, the MR-13A+ offers the most reliable, consistent results for maintaining an inventory of standard twist drill bits efficiently.
Deciding which sharpener fits your needs depends on your workspace and the type of bits you use. If you require a tool for the jobsite, choose a portable, compact option like the drill-powered sharpener. For specialized woodworking, select a dedicated mortise chisel sharpener to ensure the correct geometry. If you maintain a large collection of standard bits in a garage or workshop, invest in the VEVOR MR-13A or MR-13A+ for their superior precision and ease of use. Always verify the bit size capacity and point angle adjustability to ensure the tool matches your specific inventory before making your final purchase.
