Drill Bit Sharpener for Cordless Drills Keltin 2–12.5 mm (200)

The Keltin Drill Bit Sharpener for Cordless Drills 2–12.5 mm (200) is a compact attachment designed to be mounted directly to a cordless drill or driver. It accepts round shank twist drills from 2 to 12.5 mm and restores cutting edges on worn drill bits used for general metal and wood drilling. The unit provides a straightforward on-site resharpening solution that helps extend the service life of drill bits and maintain drilling performance without the need for separate bench grinding equipment.

Advantages

This sharpener offers precise grinding geometry suitable for most standard twist drill profiles and fits a wide size range of round shank bits. Its compact design allows easy mounting on typical cordless drills, enabling resharpening at the point of use. By restoring cutting edges quickly, it reduces downtime and lowers the need to replace worn bits as frequently. The device is engineered for portability and simple operation, making it practical for workshop and on-site applications.

Suitable for

• Resharpening standard twist drill bits with round shanks (2–12.5 mm)
• Field and workshop maintenance where a cordless drill is available
• Restoring bits used for drilling general metal and wood
• Tradespeople and technicians who require fast on-site tool maintenance

Key specifications

• Compatible drill bit shank diameter: 2–12.5 mm
• Intended for use with cordless drills/drivers as the drive source
• Suitable for standard twist drill geometries for metal and wood
• Compact, lightweight attachment for portable resharpening

How to use

Secure the sharpener attachment to the chuck of a compatible cordless drill according to the product's mounting method. Insert the round shank drill bit into the sharpening sleeve or guide, align it to the recommended angle for the intended material, and run the drill at the suggested speed while applying light, steady pressure to create a uniform cutting edge. Inspect the bit periodically to avoid over-grinding and ensure accurate flute and point geometry. Follow any safety guidance provided with the unit, including using eye protection and securing workpieces as needed.

Usage recommendations

Use the sharpener with drill speeds appropriate for the bit diameter and material; smaller diameters typically require higher speeds, while larger diameters and harder materials benefit from moderate speeds and light pressure. Perform frequent visual checks during sharpening to preserve the correct point angle and flute clearance. Store the tool in a dry place and clean abrasive residues after use to maintain consistent performance.
