Overview

The 1/4 665752117897 is a pneumatic die grinder rated at 25000 RPM and weighing 12.32 oz, making it one of the lightest options in the batch. Its $16.79 price is so far below the next-cheapest tool that it occupies its own budget tier entirely.

The 302-review count is meaningful for a budget tool at this price, and 100 units purchased last month indicates the listing is active and the product is in current distribution. The 4.3-star score is the lowest in this comparison, which is consistent with budget-tier build expectations.

Buyers approaching this tool should treat it as a low-commitment entry point for occasional use. The specs that are published, specifically 25000 RPM and 12.32 oz, are favorable on paper. The absence of PSI, CFM, and collet size information means shoppers need to confirm compatibility with their compressor and accessories before ordering.

Pros

  • $16.79 is the lowest price in this batch by a wide margin
  • 25000 RPM matches the speed of much more expensive corded and cordless grinders
  • 12.32 oz is the lightest die grinder in this comparison
  • 100 units bought last month confirms active current availability

Cons

  • 4.3 stars is the lowest rating in this batch, reflecting budget-tier build quality
  • No PSI, CFM requirements, or collet size are published in the specs
  • Brand identity and service support are not established for warranty or parts

Performance notes

Power source: pneumatic (air powered). Speed: 25000 RPM. Weight: 12.32 oz. The 12.32-oz weight is the lowest in the batch, which makes this grinder extremely easy to maneuver. At 25000 RPM it can handle light deburring and finishing. For demanding sustained grinding tasks, the unknown build quality at this price point introduces more risk than premium competitors.

What buyers say

Owner reviews reflect that most buyers purchasing this tool are motivated primarily by price and are using it for occasional or light-duty shop tasks. Positive feedback centers on the value and speed spec. Critical reviews cite build consistency and limited spec transparency as concerns.

Frequently asked questions

What compressor do I need for this pneumatic die grinder?

The published specs do not list required PSI or CFM. Check the product listing for compressor requirements or contact hello@toolgalaxy.com for guidance before purchasing.

Is the 665752117897 die grinder worth buying over a name-brand option?

At $16.79 versus the next cheapest alternative at over $45, the price difference is substantial. For light occasional use with an existing compressor it can be worthwhile. For regular or professional use, a higher-rated tool from DEWALT, Ingersoll, or SUNTECH offers more confidence.
