Carry The Right Kit Without Digging For Every Tool

A tool bag earns its place when you can reach the tool you need without unloading everything else first. Starrett tool bags are built around portable organisation, with small, medium & large configurations for service calls, workshop-to-site transport & everyday trade kits. Depending on the model, buyers can choose zipped storage for greater enclosure or open-top access when speed matters more than closing the main compartment.

Carrying Starrett measuring equipment between workshop & site? Starrett | Tool Storage & Cases provides more specialised protection options. For the hand tools that often form part of a mobile service kit, Starrett | Machinists Tools provides another closely related Starrett range.

Small, Medium Or Large – Start With The Job, Not The Bag

The biggest bag is not automatically the most useful.

A service technician carrying a compact diagnostic plus hand-tool kit has different requirements from a carpenter or maintenance fitter moving a larger selection between jobs.

Starrett's tool bag range centres on three configurations:

Those differences change how each bag behaves during a working day.

BGS → compact mobility

BGM → enclosed higher-capacity transport

BGL → rapid tool visibility plus access

Choose around the kit you actually carry rather than unused capacity.

Starrett BGS – A Compact Bag For Shorter Jobs

Not every callout needs half the workshop.

The Starrett BGS Small Tradesman's Tool Bag is intended for compact everyday kits plus smaller service jobs.

At approximately 300 × 170 × 220 mm, it combines:

► Zippered main compartment
► 12 external pockets
► 6 internal pockets
► External fastening pocket
► Carry handle
► Removable shoulder strap
► Reinforced base
► Approximately 10 kg load capacity

This format makes sense when mobility matters more than maximum storage volume.

Think:

► Inspection tools
► Tape measure
► Marking equipment
► Utility knife
► Small hand tools
► Service consumables
► Electrical hand tools
► Compact maintenance kit

A smaller bag can also discourage the familiar habit of carrying tools that never leave the bottom.

BGM – When A Compact Bag Becomes Too Small

There is a point where forcing more tools into a small bag stops being organisation.

The Starrett BGM Medium Tradesman's Tool Bag increases usable space while retaining an enclosed zipped format.

Its approximate dimensions are:

400 × 220 × 320 mm

with:

► 7 external pockets
► 6 internal pockets
► Zippered main compartment
► Carry handle
► Adjustable removable shoulder strap
► Reinforced waterproof base
► Approximately 23 kg rated load

The reinforced base is particularly useful when the bag regularly moves between workshop floors, vehicles plus jobsites where the surface underneath it may be damp, dirty or abrasive.

For broader mobile storage options beyond one bag format, Portable Organisers provides a useful supporting collection.

BGL – Open The Top & See The Tools

Some trades value access more than enclosure.

The Starrett BGL Large Tool Bag takes a noticeably different approach from the BGS plus BGM.

Instead of a zipped main compartment, the BGL uses an open-top configuration designed to keep frequently used tools visible plus easy to reach.

Its approximate dimensions are:

410 × 240 × 270 mm

with:

► 21 external pockets
► 5 internal pockets
► 8 elasticated tool holders
► Reinforced internal base
► Rugged crossbar carry handle
► Removable shoulder strap
► Approximately 16 kg rated load

That makes the BGL particularly attractive when tools are repeatedly coming out plus going back throughout the day.

Carpenters, plumbers, installers plus maintenance technicians can benefit from seeing handles, drivers, measuring tools plus accessories without opening a main zip every time.

Zipped Bag Vs Open-Top Bag

Which layout is better?

Neither—until you define the job.

If your bag spends most of its life travelling, a zipped format can make sense.

If it becomes a mobile workstation beside you, open access may be more valuable.

Electricians – Organise By Task Instead Of Tool Size

An electrician's bag can quickly become a mixture of cutters, drivers, testers, tapes, bits, hole-making accessories plus consumables.

A better packing approach groups equipment by use.

For example:

external pockets

Frequently reached hand tools.

main compartment

Larger kits plus less frequently used equipment.

small internal pockets

Items that disappear easily.

separate organiser

Connectors, terminals plus small consumables.

Wiring & Connectors provides a relevant pathway for the electrical consumables that commonly travel alongside the hand-tool kit.

Avoid letting sharp loose components share space with sensitive measuring or testing equipment.

Maintenance Fitters – Build The Bag Around The Breakdown

Maintenance work rarely announces exactly what will be required before the fitter reaches the machine.

That makes kit selection a balance.

Carry too little & every second repair requires a trip back to the workshop.

Carry everything & the bag becomes heavy, disorganised plus unpleasant to use.

A practical maintenance kit might prioritise:

► Common spanners
► Screwdrivers
► Hex keys
► Pliers
► Measuring tools
► Marking tools
► Small inspection equipment
► Common consumables
► Frequently required replacement items

For wrench-based maintenance kits, Spanner & Wrench Sets provides a complementary collection.

The aim is not to put the entire toolbox over your shoulder.

It is to cover the highest-frequency jobs efficiently.

Protect Precision Tools Differently From General Hand Tools

A tool bag can protect equipment during transport, but not every instrument should simply be dropped into the main compartment.

Precision measuring equipment deserves more deliberate handling.

A micrometer sitting underneath pliers, files plus loose sockets can experience impacts it was never intended to absorb.

Where possible:

► Keep measuring instruments in their supplied case
► Separate sharp tools from precision surfaces
► Avoid loose metal-to-metal contact
► Use dedicated pockets for frequently carried measuring tools
► Don't overload pockets until tools are forced against each other
► Keep dirt plus swarf away from instrument cases

For precision Starrett instruments frequently carried between jobs, Starrett | Micrometers completes the three direct Starrett pathways on this page.

Should Every Pocket Be Full?

No.

Empty space can be useful.

A bag packed to maximum capacity creates three problems:

visibility drops

You cannot immediately see what is missing.

access slows

One tool needs to be removed to reach another.

weight climbs

The shoulder carries tools that may contribute nothing to the day's work.

A better question than “What else can I fit?” is:

What do I repeatedly use?

That shift turns a bag from storage into a working kit.

Tool Bags For Automotive Service Work

Automotive technicians often move between a main toolbox, vehicle, hoist plus diagnostic area.

A portable bag can be useful for a targeted task kit rather than carrying individual tools backwards plus forwards.

Examples include:

► Interior work
► Roadside repair
► Electrical diagnosis
► Under-bonnet service
► Inspection work
► Mobile maintenance
► Accessory installation

For a view of what working automotive technicians actually deal with through a normal day, A Day With An Automotive Mechanic Peninsula provides a particularly relevant read for this collection.

Carpenters & Installers – Visibility Can Beat Maximum Capacity

A carpenter reaching for a square, tape, knife, pencil or driver repeatedly does not want those tools buried beneath a large kit.

This is where an open-top design such as the BGL has a different advantage.

The large number of external pockets plus elastic holders can keep common tools visible around the perimeter while larger items sit centrally.

That can make the bag function almost like a portable bench-side organiser.

The important part is consistency.

Put the same tools back into the same locations.

Over time, an empty pocket becomes an immediate visual warning that something has been left behind.

How Heavy Should You Load A Tool Bag?

A manufacturer's rated load is a capacity limit—not a recommendation that every user should carry that weight all day.

The BGM, for example, is rated for considerably more load than the smaller BGS.

That doesn't mean a 23 kg everyday shoulder bag is the right ergonomic choice for every worker.

Consider:

► Walking distance
► Stairs
► Ladder access
► Vehicle-to-site distance
► How frequently the bag is lifted
► Shoulder versus hand carrying
► Individual workplace manual-handling requirements

If a kit becomes excessively heavy, split it by task.

A lighter core bag plus secondary organiser can be more useful than one overloaded bag.

Shoulder Strap Or Carry Handle?

Use each for what it does well.

Shoulder strap

Useful when walking further or when a free hand is needed for another item.

Carry handle

Useful for shorter lifts, moving around a workshop plus controlled placement into vehicles or onto benches.

Before lifting:

► Check that the strap is attached correctly
► Make sure closures are secure
► Keep loose tools from protruding dangerously
► Check the load is balanced
► Lift according to workplace requirements

A bag is portable storage.

It should not become a manual-handling problem.

Don't Let Small Parts Take Over The Main Compartment

Loose fasteners, blades, drill bits, terminals plus accessories have an impressive ability to migrate to the bottom of a tool bag.

Once that happens, finding one item means digging through everything else.

Use a separate small-parts organiser where practical.

Drawer Organisers can also support the workshop end of the system, giving tools plus consumables defined locations when they are not travelling.

The strongest setup often combines:

workshop storage → portable kit → task-specific organiser

rather than expecting one bag to solve every storage problem.

A Tool Bag Can Also Tell You What's Missing

Organisation is not just about finding tools.

It helps identify absence.

If every frequently used tool has a habitual pocket, you can scan the bag before leaving site.

Missing screwdriver?

Empty slot.

Tape measure still on the machine?

Empty pocket.

Marker left at the installation?

Its usual position is vacant.

That is a simple advantage, but it can save return trips plus reduce lost tools.

Wet Floor? Pay Attention To The Base

A bag's underside takes more punishment than many buyers consider.

Workshop floors can contain:

► Water
► Dust
► Oil residue
► Abrasive grit
► Metal swarf
► Concrete debris

The Starrett BGM uses a reinforced waterproof base, helping isolate the main bag from the surface beneath it.

The BGL also incorporates a reinforced internal base with plastic supports.

Even with reinforced construction, avoid deliberately placing the bag into coolant, standing water or heavy contamination.

Durability still benefits from sensible use.

Before Buying – Lay Your Current Kit Out

This is one of the simplest ways to choose between BGS, BGM plus BGL.

Put the tools you actually carry on a bench.

Then divide them into:

must carry

Used on most jobs.

sometimes carry

Needed for particular tasks.

workshop only

Rarely required away from the main toolbox.

Now assess:

► Tool length
► Number of hand tools
► Loose accessories
► Sensitive equipment
► Required enclosure
► Expected load
► Frequency of access

The correct bag usually becomes much clearer.

Expert Tips – Make The Bag Work Like A Kit

Put high-frequency tools outside. Save internal storage for items that need more enclosure or are used less often.

Don't choose by litres alone. Pocket layout can matter more than total volume.

Build task kits. Electrical, inspection, installation or maintenance bags can be more efficient than one universal pile of tools.

Keep precision tools cased. A soft bag does not replace the protective case supplied with a measuring instrument.

Use the same pocket every time. Consistency makes missing tools easier to notice.

Review the bag monthly. Remove tools that have travelled for weeks without being used.

Keep consumables contained. Small loose components quickly turn the bottom of a bag into clutter.

Clean the base. Don't transfer workshop contamination straight into a vehicle, office or customer's premises.

Your Tools Don't Need To Live Loose In The Ute

Portable organisation matters between jobs as much as during them.

A properly packed bag can reduce:

► Tools rolling around vehicle storage
► Small items disappearing
► Time spent assembling a kit before each callout
► Unnecessary trips back to the toolbox
► Damage caused by loose equipment contacting other tools
