Secure hold for precise sharpening: The sharpening tool clamps the drill bit firmly during grinding, keeping the bit at a consistent angle for repeatable results. Multisize notches for versatility: Notches sized for multiple drill bit diameters let you easily polish different angles on a range of bits. Prolonged bit life and better performance: Keeping bits sharp extends their useful life, reduces the need for replacements, and improves drilling tasks. Stable, even sharpening every time: The design provides stable support to deliver uniform, sharp edges on every use. Compatibility and use: Notches accommodate a range of standard drill bit sizes, enabling effective sharpening across common tasks. Use scenario: In a home workshop, refresh drill bits used for woodworking and light metalworking to maintain clean, accurate holes. Use scenario: On a job site or in a , manage different bit sizes efficiently with the sizespecific notches to maintain consistent angles. Use scenario: During maintenance tasks, extend the life of frequently used drill bits by keeping their edges sharp between replacements.
