Harbor Freight does not currently stock a dedicated drill bit sharpener. Check the category page yourself and it comes back empty. That surprises a lot of shoppers.
Most assumed the cheap sharpening jig was still on a shelf near the drill bit sets. Harbor Freight does carry a bench grinder or angle grinder for freehand work. They also sell an unrelated chainsaw sharpener that gets mixed up with drill bit sharpening in search results.
Owners who used the older drill bit sharpener units describe stones that wore out fast. Edges came out worse than they started.
Harbor Freight is not really in the dedicated drill bit sharpener business anymore. This guide covers what they actually offer, why the old sharpener tier drew such rough reviews, and where the Drill Doctor line fits as the real step up.
What Harbor Freight actually sells for drill bit sharpening
A search for a drill bit sharpener at Harbor Freight turns up drill bit sets, not sharpening tools. The closest matches are a Chicago Electric chainsaw sharpener, a diamond hone block, and a combination sharpening stone. None of those reshape a dull twist bit the way a purpose built jig would.
That leaves two real paths at Harbor Freight for anyone trying to save a box of dull bits. The first is freehand grinding on a bench grinder or angle grinder. You use the wheel edge to restore the cutting angle by hand.
The second path skips Harbor Freight entirely and buys a dedicated bit sharpener from a specialist brand.
Neither path is a Harbor Freight drill bit sharpener. That product is not currently part of their lineup. That is the honest starting point before comparing anything else.
What actually matters when you pick a sharpening method
Three things decide whether a sharpening method is worth your time. How consistent is the resulting angle. How much bit do you lose per pass.
How steep is the learning curve before you stop ruining bits.
- Angle consistency. A jig locks the same angle every time. Freehand grinding depends entirely on your hand and eye.
- Material loss. Aggressive stones or heavy freehand passes eat more of the bit than a controlled jig does.
- Learning curve. Freehand grinding takes practice on scrap bits before it is reliable. A jig is closer to load and pull.
A cheap sharpening stone or a worn out attachment fails on the first point almost every time. That is exactly the complaint pattern around the discontinued Harbor Freight sharpener units.
| Model | Type | Best for | Price band | |
|---|---|---|---|---|
| Drill Doctor 750X | Powered sharpening jig | Frequent users, mixed bit types | Around $160 | |
| Drill Doctor 500X | Powered sharpening jig | Occasional home use | Around $110 | See Current Price |
| Bench or angle grinder freehand | Manual technique | Larger bits, occasional touch ups, zero added cost if you already own a grinder | No dedicated cost |
Drill Doctor: the real step up from freehand
The Drill Doctor line is the step up owner discussions keep pointing toward. It offers a repeatable drill bit sharpener rather than a grinder workaround. Both models are built specifically for restoring twist bits, not adapted from another tool.
Drill Doctor 750X
Best Overall
Powered sharpening jig | dedicated drill bit sharpener | around $160
The 750X sits at the top of the Drill Doctor lineup. It carries the strongest owner ratings of the two models here. It is the pick for anyone sharpening a real mix of bit types on a regular basis, not just an occasional dull bit.
Owner reviews repeatedly mention the guided setup as the reason it beats freehand grinding for consistency. It costs more than the 500X. That premium only pays off if you actually use it often.
Pros
- Highest owner rating of the two models on the manufacturer site
- Built specifically for twist bit geometry, unlike a general purpose grinder
- Repeatable results once set up correctly
Cons
- Costs noticeably more than the 500X
- Overkill for someone who sharpens a handful of bits a year
Drill Doctor 500X
Best Value
Powered sharpening jig | dedicated drill bit sharpener | around $110
The 500X is the lighter, cheaper entry point into the same Drill Doctor family. It suits a home shop that sharpens bits occasionally. It fits anyone who wants a jig instead of learning freehand grinding.
It carries fewer manufacturer site reviews than the 750X. That makes the pattern harder to read with confidence. Treat it as the budget option in the lineup rather than a fully proven quantity.
Pros
- Lower cost entry into a purpose built sharpener
- Simpler than learning freehand grinding from scratch
- Same core Drill Doctor approach as the 750X
Cons
- Smaller review sample on the manufacturer site than the 750X
- Fewer capabilities than the step up model
The freehand path on a Harbor Freight grinder
If you already own a bench grinder or angle grinder, freehand sharpening costs nothing extra. Experienced owners generally reserve this method for larger bits, roughly half inch and up. A small angle error matters less on a bigger bit.
Smaller bits are harder to hold steady against a spinning wheel. It is easy to grind past the point you meant to stop. Budget bench grinders run under $100.
Heavier duty units with dual wheel setups run closer to $200. Either works for this job; the wheel and your hand matter more than the grinder brand.
For a full walkthrough of the technique itself, our step by step guide to reshaping a dull twist bit edge covers hand position, angle checks, and how to avoid overheating the bit.
Mistakes to skip
- Do not assume Harbor Freight still sells a drill bit sharpener. Check current listings before you drive to a store expecting one.
- Do not freehand small bits without practice. Start on scrap bits, not the one you actually need this afternoon.
- Do not buy the cheapest unbranded sharpening stone expecting jig level results. A stone reshapes an edge; it does not hold an angle for you.
- Do not confuse a chainsaw sharpener with a drill bit sharpener. They show up together in search results but do completely different jobs.
The bottom line: Harbor Freight does not currently sell a dedicated drill bit sharpener. Do not go in expecting one.
If you sharpen bits often, the Drill Doctor 750X is the more capable buy. Freehand grinding on a bench grinder covers occasional larger bit touch ups for free.
FAQ
Does Harbor Freight sell a drill bit sharpener?
Not currently. Their drill bit sharpener category listing is empty. A site search returns drill bit sets and unrelated sharpening accessories instead of a dedicated unit.
What did Harbor Freight sell for drill bit sharpening before?
Owner discussions reference an older drill bit sharpener unit that is no longer listed. The recurring complaint was a stone that wore quickly and damaged bits rather than restoring them.
Is the Drill Doctor better than freehand grinding on a Harbor Freight grinder?
For consistency, yes. A jig holds the same angle every pass.
Freehand grinding depends on practiced hand control. It works best on larger bits, where small errors matter less.
Which Drill Doctor model should I buy, the 750X or the 500X?
The 750X fits frequent sharpening across a range of bit types. The 500X is the lighter, cheaper entry point for occasional home use.
Can I sharpen drill bits on any Harbor Freight bench grinder?
Yes, freehand, using the wheel edge to restore the cutting angle by hand. It works on any bench or angle grinder, not a specific model. It suits larger bits more than small ones.
Is Harbor Freight’s chainsaw sharpener useful for drill bits?
No. It is built for chain teeth, a completely different geometry. See our separate look at Harbor Freight’s chainsaw sharpener if that is the tool you actually need.
