Tools shape the way we build, repair, and create. From the workshop to the construction site, having the right equipment on hand can turn a difficult task into a simple one. In this guide, we’re focusing on tools that start with the letter A — a surprisingly long and useful list that covers hand tools, power tools, and even software.
Whether you’re a DIY beginner, a tradesperson brushing up on terminology, or simply curious about tool names in English, this article breaks down 20 practical tools that start with A, what they’re used for, and how to choose the right one for your project.
List of Tools That Start with A
Here’s a quick overview of the tools we’ll cover in this article:
- Adjustable Wrench
- Allen Key
- Air Compressor
- Angle Grinder
- Axe
- Auger
- Awl
- Anvil
- Aviation Snips
- Adze
- Abrasive Wheel
- Air Hammer
- Angle Finder
- Automated Software Tools
Let’s look at each one in detail, along with their uses, benefits, and best applications.
1. Adjustable Wrench
An adjustable wrench (also called an adjustable spanner) is a hand tool with a movable jaw that lets you tighten or loosen nuts and bolts of varying sizes.
Practical uses:
- Plumbing repairs and pipe fittings
- Automotive maintenance
- General household fixes where bolt sizes vary
Because one wrench replaces an entire set of fixed-size spanners, it’s a must-have for any basic toolbox.
2. Allen Key
Also known as a hex key, the Allen key is an L-shaped tool used to drive bolts and screws with a hexagonal socket.
Practical uses:
- Assembling flat-pack furniture
- Adjusting bicycle components
- Tightening screws in machinery and electronics
Allen keys usually come in sets of varying sizes, so it’s worth keeping a full set rather than a single key.
3. Air Compressor
An air compressor converts power into potential energy stored in pressurized air, which can then be used to run pneumatic tools.
Practical uses:
- Inflating tires and sports equipment
- Powering nail guns, spray guns, and impact wrenches
- Cleaning dust and debris from workspaces
Air compressors come in portable and stationary models, so the right choice depends on how often and where you’ll use it.
4. Angle Grinder
An angle grinder is a handheld power tool fitted with an abrasive disc, used for cutting, grinding, and polishing hard materials.
Practical uses:
- Cutting metal rods, sheets, and pipes
- Removing rust or old paint
- Sharpening blades and shaping stone or tile
Always use proper eye and hand protection when operating an angle grinder, since the spinning disc can throw off sparks and debris.
5. Axe
One of the oldest tools in human history, the axe features a heavy metal head attached to a long handle, designed for chopping.
Practical uses:
- Splitting and felling wood
- Clearing brush and small branches
- Survival and camping tasks
Axes vary by weight and handle length, so a smaller hatchet works better for camping while a full-size felling axe suits heavier woodcutting.
6. Auger
An auger is a drilling tool with a helical (screw-shaped) design used to bore holes into soil, wood, or ice.
Practical uses:
- Digging holes for fence posts
- Drilling through wood for plumbing or wiring
- Ice fishing
Hand augers work for small jobs, while powered augers attach to drills or standalone motors for larger digging projects.
7. Awl
An awl is a small pointed hand tool used to pierce holes in materials like leather, canvas, or wood.
Practical uses:
- Leatherworking and stitching
- Marking wood before drilling
- Punching starter holes for screws
Despite its simplicity, an awl is a favorite among crafters and woodworkers for precision marking.
8. Anvil
An anvil is a heavy block of metal used as a solid surface for shaping metal through hammering.
Practical uses:
- Blacksmithing and metal forging
- Shaping horseshoes and metal parts
- Straightening bent metal pieces
A quality anvil should be heavy and stable enough to absorb repeated hammer strikes without shifting.
9. Aviation Snips
Aviation snips (or tin snips) are heavy-duty scissors designed to cut through sheet metal cleanly.
Practical uses:
- Cutting ductwork and metal sheeting
- HVAC installation and repair
- Trimming metal roofing materials
They typically come in three types — straight-cut, left-cut, and right-cut — depending on the curve of the cut needed.
10. Adze
An adze is a cutting tool similar to an axe, but with the blade set perpendicular to the handle, used mainly for shaping wood.
Practical uses:
- Hollowing out wood for bowls or canoes
- Smoothing rough-cut lumber
- Traditional carpentry and woodcraft
While less common today, adzes remain popular among woodworkers who prefer hand-shaping over powered tools.
11. Abrasive Wheel
An abrasive wheel is a rotating disc coated with abrasive particles, used for grinding, cutting, or polishing hard surfaces.
Practical uses:
- Sharpening blades and cutting tools
- Grinding welds smooth
- Removing rust and surface imperfections
Abrasive wheels are often attached to bench grinders or angle grinders, and different grit levels suit different finishing needs.
12. Air Hammer
An air hammer, also known as a pneumatic hammer, uses compressed air to deliver rapid, forceful blows.
Practical uses:
- Breaking up concrete and masonry
- Removing rivets in metalwork
- Auto body repair and dent removal
Because it runs on compressed air, an air hammer needs to be paired with a suitable air compressor.
13. Angle Finder
An angle finder (or protractor tool) measures and marks angles accurately for cutting or construction work.
Practical uses:
- Measuring roof pitches and stair angles
- Setting up miter saws correctly
- Ensuring precise joints in carpentry
Digital angle finders are increasingly popular for their quick, accurate readouts compared to manual protractors.
14. Automated Software Tools
Not all tools are physical. Automated software tools are digital programs designed to perform repetitive tasks, streamline workflows, or manage projects without manual input each time.
Practical uses:
- Automating marketing emails and social media posts
- Managing project timelines and team tasks
- Running scheduled data backups and reports
Popular categories include automation platforms, project management software, and workflow builders — all essential in modern digital workplaces.

How to Choose the Right Tool That Starts With A
Picking the correct tool depends on a few key factors:
- Match the tool to the task. A heavy-duty job like breaking concrete needs an air hammer, not an awl.
- Consider your skill level. Beginners may find simple hand tools like an Allen key easier to start with, while power tools like angle grinders require more caution.
- Check safety features. Tools like air compressors and angle grinders should have safety guards, non-slip grips, and reliable shut-off mechanisms.
- Think about long-term value. A well-made adjustable wrench or anvil will outlast a cheaper alternative and perform better over time.
- Factor in storage and portability. Compact tools like an awl or angle finder are easy to store, while an anvil needs a dedicated workspace.
Why Learning Tool Names Matters
Knowing the names and functions of tools that start with A isn’t just useful trivia — it has real, practical benefits:
- Better communication: Whether you’re following instructions or working with a team, knowing exact tool names avoids confusion.
- Improved safety: Understanding what a tool does helps you use it correctly and avoid accidents.
- Stronger vocabulary: For students and English learners, tool names are a practical way to build technical vocabulary.
- Smarter shopping: Knowing what you actually need prevents buying the wrong equipment for a job.
Final Thoughts
Tools that start with A cover an impressively wide range — from simple hand tools like the awl and Allen key to heavy-duty equipment like air hammers and angle grinders, and even modern automated software tools used in offices worldwide.
