Drill Bit Sharpener Attachment – Bring Dull Drill Bits Back to Work
NEW ARRIVAL 5/64″–1/2″ BITS 5″ GRINDER FIT
Tired of struggling with dull drill bits halfway through a project? Refresh worn cutting edges using a compatible angle grinder and get more useful life out of your everyday twist drill bits.
Sharpen what you already own. This compact attachment helps guide compatible drill bits during sharpening, without requiring a separate powered machine.
Don't Toss a Drill Bit Just Because It's Dull
A worn cutting edge can make drilling feel slower and more frustrating. Instead of replacing every dull bit, restore a usable cutting edge with a guided sharpening setup.
Less guesswork than freehand positioning. More opportunities to reuse the drill bits already in your toolbox.
One Attachment, Multiple Drill Bit Sizes
The guide openings accommodate standard twist drill bits from 5/64″ to approximately 1/2″ (2–13 mm). Keep common small and medium-sized drill bits maintained using one compact accessory.
More Control, Less Guesswork
The built-in guide positions compatible twist drill bits at an approximately 118-degree point angle. It helps maintain a repeatable position while sharpening each cutting lip with a suitable grinding wheel.
Get More From the Grinder You Already Own
Designed for compatible 5-inch angle grinders, this lightweight attachment helps turn an existing workshop tool into a drill bit maintenance setup. No separate motor or battery is needed.

A Smarter Way to Maintain Your Drill Bits
Follow the instructions supplied with your exact attachment and angle grinder. Proper installation, wheel selection, and safe handling are essential for a controlled sharpening process.
1
Check Compatibility
Disconnect the grinder from power. Verify the grinder, guard, attachment and abrasive wheel are designed to work together.
2
Secure the Attachment
Install the sharpening guide according to its supplied instructions. Tighten the mounting fasteners and check that nothing contacts the abrasive wheel.
3
Select the Correct Guide Opening
Choose the opening matching your compatible twist drill bit. Check its positioning and clearance while the grinder is switched off.
4
Sharpen Following the Manual
Wear appropriate protection and follow the manufacturer's approved sharpening procedure. Regrind both cutting lips evenly without excessive pressure or heat.
⚠ Safety First: Never operate the grinder without its required guards or proper PPE. Only use a compatible, correctly rated grinding wheel and manufacturer-approved attachment configuration. Do not use the product if the guide interferes with guards, wheel clearance, or normal safe operation.
Check the Fit Before You Buy
Designed for common drill bit maintenance, with a multi-size guided sharpening layout. Please verify your grinder model and installation dimensions before ordering.

Questions Before You Buy?
Will this fit my angle grinder?
This version is intended for compatible 5-inch (125 mm) angle grinders. Mounting dimensions and guard designs differ between models, so please confirm compatibility before purchasing. It is not a universal fit for every grinder.
What types of drill bits can I sharpen?
The guide is intended for compatible standard twist drill bits between approximately 5/64 inch and 1/2 inch. It is not intended for step bits, spade bits, hole saws, router bits or specialty cutting tools.
Does it include a grinder or sharpening wheel?
No. This product is a guide attachment, not a complete powered sharpener. You will need your own compatible angle grinder and a suitable grinding wheel approved for the operation.
Can beginners use it?
The guide can make drill bit positioning more repeatable, but safe grinder operation and sharpening still require appropriate experience, protective equipment and the manufacturer's instructions. Practice with suitable worn bits and never improvise unsafe mounting.
