Transform how you work with Apache Parquet files. One double-click replaces dozens of command lines. Now available on macOS, Windows & Linux.
Every data professional knows the struggle. You receive a Parquet file, and suddenly you're writing Python scripts just to peek inside.
Double-click a Parquet file and watch your OS shrug. No preview, no Quick Look, no native support whatsoever.
Fire up Jupyter, import pandas, write df.head()... just to see the first few rows. Every. Single. Time.
Minutes turn to hours when you're constantly context-switching between data exploration and actual analysis.
When basic queries require code, you miss opportunities. Quick questions remain unanswered.
I built this app because I was tired of the friction. Now, exploring Parquet files feels as natural as browsing photos.
Open Parquet files instantly — no scripts, no notebooks, no waiting. Your data is just a double-click away.
Write queries directly in the app. Filter, aggregate, and explore — all powered by DuckDB under the hood.
Get instant insights: min, max, null counts, unique values, and more. Right-click any column for detailed stats.
Your files stay on your device. No uploads, no tracking, no surprises — just private, local analysis.
I built Parquet Reader because I needed it myself. Every feature comes from real frustration with existing tools. If you work with Parquet files daily, this app will change your workflow.
Understanding the standard’s technical details, its differences from DIN 5480, and where to find reliable digital copies ensures that you can confidently maintain and reproduce legacy splined connections. While new designs should embrace modern, load‑driven standards like DIN 5480 or ISO 4156, the old DIN 5482 standard will continue to turn the wheels of legacy machinery for many years to come – and its PDF will remain a frequently opened file in engineering departments worldwide.
DIN 5482 is organised into several parts, of which Part 3 (space width and tooth thickness measurement) is still listed as an active document in some official catalogues, while most parts have been officially withdrawn.
With , you input your load data into a standardised calculation and verify the actual flank pressure. If the values fall within limits, you have an optimal, efficient and reliable design.

The is a German technical specification for involute splines—mechanical components that transmit torque between shafts and mating parts like gears or pulleys. While it was officially withdrawn and replaced by the more modern DIN 5480 standard , DIN 5482 remains critical for maintaining and repairing older machinery, particularly in the hydraulics and fluid flow industries. Overview of DIN 5482 Standard
Official and reference documents for DIN 5482 are typically available in the following formats:
I can provide the specific geometric breakdown or mathematical formulas required for your machining operations. Share public link With , you input your load data into
), which roughly corresponds to the major diameter of the external spline. The minor or core diameter ( ) of the external spline. 2. Geometry and Profiles
You cannot cut an internal DIN 5482 spline on a standard CNC mill without a rotary axis and a form cutter. You need a broach. Because DIN 5482 is obsolete, stock broaches are rare. You will likely need to order a custom pull broach from a company like American Broach or Karl Klink. They will ask for "DIN 5482, 1977 edition, side fit." Send them a screenshot from your PDF77.
DIN 5482 is a collection of German industrial standards that define the dimensions and measurement methods for . Officially titled “Zahnnabenprofile und Zahnwellenprofile mit Evolventenflanken” (Internal and External Involute Spline Profiles), the standard was developed in the post‑war period and gained widespread adoption from the 1960s onwards. It was originally released in multiple parts, with DIN 5482‑1 covering general dimensions, DIN 5482‑2 dealing with tolerances, and DIN 5482‑3 specifying the measurement of space width and tooth thickness using balls or pins.

is an older German industrial standard that specifies the dimensions and tolerances for involute splines with a 30° pressure angle . While it has been technically withdrawn and replaced by the more modern DIN 5480 for new designs, it remains widely used for spare parts and within specific sectors like the fluid power industry.
