Precision sharpening for workshop drill bits

The VEVOR MR-20G bench sharpener handles twist drills from 3 to 20 mm diameter using eighteen elastic collets and two supplied collet chucks. A 120 W motor spins the wheel at 4500 rpm while the point angle adjusts from 95° to 135° and the lip relief angle can be set in four positions via the pin system.

Capacity covers common workshop sizes

Eighteen collets step through every integer millimetre between 3 and 20, split across a 3-13 mm chuck and a 14-20 mm chuck for secure clamping. The CBN wheel grinds high-speed steel bits while the SDC wheel tackles tungsten carbide alloy, so both common material families are covered without extra purchases.

Bench-top unit needs only a power outlet

At 11.4 x 5.7 x 6.3 inches and 20.1 lbs the machine sits on a workbench without permanent mounting. Both grinding wheels, two hex wrenches and both collet chucks ship in the box so the sharpener is ready to use once plugged in.

Questions about this item

Will the 18 collets cover the 3 mm to 20 mm drill bits I already own?

The 18 collets are sized 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 and 20 mm, matching the full 3-20 mm range of the sharpener.

How can I verify the point angle is set correctly after adjusting the 95° to 135° scale?

Set the desired angle on the adjustable scale, secure a bit in the appropriate collet, run the 4500 RPM motor and inspect the ground tip; the point angle should match the selected value between 95° and 135°.

Which accessories are included and what must I purchase separately?

The package contains 18 collets, a pre-installed CBN wheel, an SDC wheel, M4 and M2.5 hex wrenches, plus 3-13 mm and 14-20 mm collet chucks; no extra items are required for operation.
