VEVOR Drill Bits Sharpener MR-20G 3-20mm - Precise Point & Lip Angles

Our review of the VEVOR Drill Bits Sharpener MR-20G finds it best suited for workshops and serious DIY users who want consistent, repeatable results when re-sharpening drill bits. The single biggest reason to buy is its accuracy: the unit lets you set point angle from 95 to 135 degrees and adjust lip relief with positioner pins, producing clean, factory-like edges far faster than hand sharpening. The compact, 45# steel body and included 18 collets cover 3-20mm bits, so it is ready for varied tasks right out of the box.

Key Features

• Adjustable point angle: The 95 to 135 degree range makes it easy to match angle to material and drilling speed for better performance.
• Wide collet range: Eighteen elastic collets plus two collet chucks securely accept drill bits from 3mm to 20mm for broad compatibility.
• Dual grinding wheels: Comes with a pre-installed CBN wheel and a spare SDC wheel so users can choose the right wheel for high-speed steel or tungsten alloy bits.
• Power and durability: A 120W DC motor runs at 4500 RPM and the 45# steel construction keeps the unit steady and long lasting under repeated use.
• Lip relief control: Positioner pins allow DIY adjustment of lip relief angles so bits can be tailored to different drilling needs.
• Ready to use: The package includes collets, two collet chucks and hex wrenches so sharpening can begin with minimal setup.

Who It's For

This sharpener is ideal for hobbyists, small shop owners, and maintenance technicians who sharpen a variety of drill bits frequently and need consistent geometry. Users who value speed and repeatability will appreciate being able to set specific point and lip relief angles rather than relying on hand techniques.

It is less appropriate for someone who only occasionally touches up a single bit or prefers portable, bench-free sharpening methods; those users may find a simple jig or handheld solution more convenient. Also, users expecting extensive, step-by-step printed instructions should note the product is praised for function but customers have mentioned instruction quality could be better.

Pros & Cons

Pros

• Accurate angle control for consistent bit geometry and improved drilling performance.
• Comprehensive collet set covers 3-20mm so few bits are left out.
• Choice of CBN or SDC wheel for compatibility with HSS or carbide materials.
• Robust build and quiet, high-RPM motor make it feel like a shop-grade tool.

Cons

• Instruction quality could be clearer, so first-time users may need to experiment to dial in angles.
