10 Best Drill Bit Sharpeners 2025 in the United States

The MR-20G drill bit sharpener is a solid choice if you regularly use drill bits between 3mm and 20mm in diameter. Its standout feature is the ability to precisely adjust the point angle from 95° to 135°, along with customizable lip relief angles, which helps keep your drill bits accurate and effective for different tasks. The included 18 elastic collets make it versatile, fitting a wide range of bit sizes without hassle. The machine uses a CBN grinding wheel, which is excellent for sharpening high-speed steel bits, delivering good precision and durability. Powered by a strong DC motor running at 4800 RPM, it works efficiently with relatively low noise.

While it weighs around 20 pounds and requires an AC power source, which limits portability for on-the-go jobs, it suits well for workshops, garages, or home use where power outlets are available. The design emphasizes ease of use with stable operation and safety features like a professional collet chuck. However, it’s bulkier than handheld sharpeners and not battery-powered, so it’s less convenient if you want something truly portable.

Since it doesn’t include batteries or cordless options, it needs to be plugged in. If your focus is on maintaining drill bits with precision and you have a fixed workspace, this sharpener provides excellent value and performance within its category.

It includes the Tormek T-8 Original Sharpener, various jigs and accessories for hand tools, woodturning tools, planer blades, and drill bits. The machine operates at low RPM and is water-cooled, ensuring precision and long tool life.

Durability is another strong point, with the machine and its components built from high-quality materials like zinc alloy, which enhances its longevity. The construction appears robust and designed for intensive use. However, the setup can be quite bulky, which may hinder portability. With dimensions of 16 x 16 x 16 inches and a weight that isn't specified, it is not the most portable option.

Ease of use is moderately high due to the detailed jigs and the comprehensive nature of the kit, but the initial setup and learning curve can be steep, particularly for beginners. The machine operates on 115 volts, which limits its use to North America unless a converter is used, which could potentially damage the machine.

In summary, the Tormek T-8 Ultimate Plus Kit is a powerful, precise, and durable sharpening system well-suited for professional users or serious hobbyists with a wide range of sharpening needs. Its versatility and high-quality build are significant advantages, though its bulk and region-specific power requirements may be limiting factors for some users.
