A Hunker report describes the MDPSDS Drill Bit Sharpener, a compact plug-in tool with 19 bit slots and a preset 130-degree sharpening angle. Hunker cites nearly 200 Amazon reviews averaging 4.3 out of 5 stars, but the source does not provide independent performance tests, pricing, or a product-maker statement.
Hunker has reported on the MDPSDS Drill Bit Sharpener, a compact plug-in tool designed to sharpen bits through 19 preset slots rather than requiring users to hold each bit against a grinding wheel by hand. The tool is listed with a 130-degree sharpening angle; Hunker says that nearly 200 Amazon reviewers gave it an average rating of 4.3 out of 5 stars at the time of its report.
According to Hunker’s account, users select a slot that fits the bit, insert the bit, turn it to align its tip with the grinding stone and press the start button. The tool’s preset grinding angle and snug-fitting slots are intended to guide the sharpening process. The report lists 19 slots for bits from 1/8 to 15/32 inch, with sizes marked in both metric and SAE units.
Hunker says sharpening should take only a few seconds with light or moderate downward pressure. It cautions users not to force the bit into the tool: excess pressure can make the motor work harder and remove too much material, potentially shortening the bit’s usable life. The report does not provide independent test results or a detailed assessment of how consistently the sharpener performs across different bit materials and conditions.
The tool’s listed 130-degree angle falls between commonly used angles cited by Hunker: about 118 degrees for wood bits and 135 degrees for metal-boring bits. That makes the preset a compromise rather than an exact match for either stated angle. Hunker notes that a sharper point may cut metal faster, while also warning that it can dull sooner and generate more friction during drilling.
A Shortcut for Workshop Sharpening
A dedicated sharpener may help workshop users restore bits without learning to maintain a consistent angle against a bench grinder or belt sander. That matters because a dull bit can progress slowly, overheat and, particularly when narrow, break under continued use, according to Hunker’s explanation. A guided tool could make basic upkeep more accessible, though the report does not establish that it replaces careful technique or is suitable for every bit.
The compromise angle also has practical consequences. Users drilling different materials may value a tool that handles common bit sizes without manual angle adjustment, but a single preset does not provide the material-specific geometry described in the report. For metal drilling, Hunker advises watching for overheating, especially when using a sharpened tip that may create more friction. The product’s convenience should not be read as a guarantee of faster work or longer bit life.

Preset Angles and Bit Sizes
Drill bits need two cutting bevels sharpened at the tip, rather than the single point formed on a pencil. Hunker describes manual sharpening as a process that requires the user to hold and adjust the bit against a grinding surface. The MDPSDS tool instead uses a fixed stone angle and size-specific slots to guide placement. The source frames that setup as easier to use, but does not compare it with other sharpeners or provide controlled test data.
The report’s Amazon figures are a snapshot, not a long-term measure of performance: nearly 200 reviews and an average of 4.3 out of 5 stars were reported as of publication. Hunker says no reviewer complained that the tool failed to sharpen bits and quotes one customer describing bits as acting “brand new” for the time being. Those are customer-review observations reported by Hunker, not independently verified test findings.
“The MDPSDS tool is designed to hone bits to a 130-degree angle.”

Performance Beyond Customer Reviews
Independent performance data is not provided in the source material. It does not say how the sharpener performs on worn, chipped or unusually shaped bits, how long its grinding stone lasts, or whether results vary by bit material. The cited review count and score may also change over time and should be treated as figures from the report’s publication, not a current live rating.
The source does not state the product’s price, warranty, availability, power specifications or manufacturer guidance. It also does not establish whether the 130-degree angle is appropriate for a reader’s particular drilling task. Buyers should check the product’s current listing and instructions rather than assume the reported specifications cover every use.
Check the Listing Before Use
The next practical step for anyone considering the tool is to verify its current price, specifications, included accessories and user instructions with the seller or manufacturer. The Hunker report provides no announcement of a product launch or change; it is a product-focused report, and the review figures are tied to when it was written.
Users who already own the sharpener should follow its instructions, choose a slot that matches the bit and use light or moderate pressure. During metal drilling, Hunker advises monitoring for heat and says a bowl of water can be kept nearby to cool a hot bit. Do not continue drilling with a bit that is overheating or damaged; stop and inspect it before proceeding.
Key Questions
What is the MDPSDS Drill Bit Sharpener?
Hunker describes it as a compact, plug-in tool that guides drill bits against a grinding stone through size-specific slots.
What bit sizes does the tool accommodate?
The report lists 19 slots covering bits from 1/8 to 15/32 inch, with metric and SAE markings.
Is its 130-degree angle ideal for every material?
No. Hunker describes 130 degrees as a midpoint between the approximately 118-degree angle it cites for wood bits and 135 degrees for metal-boring bits. The source does not claim the preset is ideal for every bit or task.
What did Amazon reviewers rate it?
Hunker reported an average score of 4.3 out of 5 stars from nearly 200 Amazon reviews as of publication. The score may have changed since then, and it is not an independent product test.
How should users avoid damaging bits while sharpening?
Hunker recommends light or moderate pressure rather than forcing the bit into the sharpener, which can remove too much material. During metal drilling, monitor for overheating and stop if the bit becomes excessively hot.
