Individual Drill Bits for Replacement, Replenishment & Trade Work
Shop Sutton Tools Jobber Carded Drills in Australia when you need a specific drill size, a replacement for a worn bit or a drill better matched to the material you're working with. Individual carded jobber drill bits give fabricators, fitters, mechanics, maintenance teams & tradies the flexibility to replace the sizes they actually use without buying another complete drill set.
Sutton's jobber drill range covers everything from everyday workshop drilling through steel, aluminium, brass, timber & plastics to more demanding stainless-steel applications. Depending on the job, options include general-purpose HSS, XP Bullet, Inox & Heavy Duty Cobalt drill families.
Choosing the right drill involves more than matching the diameter. Consider the material you're drilling, required hole size, drilling conditions, the power tool or machine being used & the type of drill best suited to the application.
Browse Drills for other drilling formats or Drill Accessories to complete your drilling setup.
Replace the Drill Size You Actually Use
A workshop drill set might contain dozens of sizes, but some diameters inevitably get used far more often than others.
When a frequently used drill becomes worn, damaged or lost, an individually carded Sutton jobber drill lets you replace that specific size without purchasing another complete set.
Before ordering, check:
► Required drill diameter
► Material being drilled
► Hole depth
► Through-hole or blind-hole requirement
► Drill chuck capacity
► Handheld or machine drilling
► Frequency of use
The diameter determines the size of the hole, while the material & working conditions help determine which drill is better suited to making it.
Drilling Mild Steel & General Workshop Materials
Not every steel hole requires a specialist drill.
For everyday fabrication, repairs, brackets, fixtures & general workshop work, a quality HSS jobber drill can provide a practical solution across common materials.
Typical applications include:
► Mild-steel fabrication
► Brackets & mounting plates
► Machinery repairs
► Automotive workshop jobs
► Aluminium components
► General maintenance
► Timber & plastic drilling
► Trade installation work

Stainless Steel Needs a Different Approach
Stainless steel can be demanding on drills.
Excessive heat, insufficient feed or allowing the drill to rub rather than cut can make the hole increasingly difficult to complete.
Sutton Inox Jobber Drills are designed specifically for stainless-steel drilling. Their construction & cutting geometry are developed to provide greater control when working in materials where heat, swarf management & effective penetration matter.
For regular stainless work:
► Use a drill suited to stainless steel
► Secure the workpiece firmly
► Keep the drill aligned
► Select an appropriate cutting speed
► Maintain effective feed pressure
► Use suitable cutting fluid where required
► Avoid prolonged rubbing
► Keep the cutting edges in good condition
If the drill stops cutting effectively, simply increasing speed isn't necessarily the answer.
Fabricators: Choose Around the Material You Use Every Day
A fabrication workshop may move through mild steel, stainless steel, aluminium & other metals during the same week.
The best drill for one material isn't automatically the best choice for every other job.
Mostly Mild Steel & General Materials
A general-purpose HSS jobber drill can be a practical everyday option for common fabrication, maintenance & workshop drilling.
Frequent Stainless Steel
Consider a drill developed specifically for stainless-steel work, such as an appropriate Sutton Inox option.
Demanding Metal Drilling
Heavy Duty Cobalt drills can be worth considering where tougher materials, higher cutting temperatures or repeated drilling place greater demands on the cutting edge.
Repetitive Workshop Drilling
As hole quantity increases, tool life, chip evacuation, heat management & consistency become increasingly important.
For workshops performing the same operation repeatedly, correct drill selection can make a noticeable difference over the working day.
Maintenance Teams: Keep Common Sizes Ready
Maintenance work rarely happens at a convenient time.
A guard needs repairing. A bracket needs another mounting hole. A damaged fixing needs replacing. A machine modification requires a hole before production can restart.
For maintenance teams, individually carded jobber drills make it easier to replenish frequently used sizes as they're consumed.
Rather than replacing an entire drill set because a handful of common diameters are worn, keep those working sizes available individually.
This approach is useful for:
► Factory maintenance
► Plant repairs
► Machinery servicing
► Workshop breakdowns
► Site maintenance
► Fleet repairs
► General engineering

Mechanics: Think Beyond Drill Diameter
Automotive drilling can involve very different materials, thicknesses & access conditions.
A pilot hole through sheet metal isn't the same job as drilling a heavier fabricated bracket.
Before starting, consider:
► Material type
► Material thickness
► Access around the hole
► Required diameter
► Accuracy required
► Workpiece support
► Components behind the drilling position
That last check matters.
Before drilling vehicle panels, fabricated assemblies or machinery, know what's behind the surface. Wiring, hoses, trim, moving components & other hidden parts can turn a straightforward drilling job into an expensive repair.
Sutton XP Bullet for Fast, Controlled Drilling
Sutton XP Bullet Jobber Drills are designed around efficient drilling, easier starting & effective chip removal.
Their self-centring point geometry helps establish the drill at the intended position, while the flute design assists with moving chips away from the cutting edges.
That can make XP Bullet particularly useful when working with a cordless drill & looking for:
► Easier starting
► Reduced wandering
► Effective chip removal
► Lower drilling effort
► Reliable handheld performance
As with any drill, the material & application still matter. The benefit comes from matching the drill design to the type of work being performed.
Why the Drill Point Matters?
Before a drill can produce an accurate hole, it needs to establish its position.
A drill that wanders during the start can leave the finished hole away from the intended mark.
Self-centring or split-point geometry can help improve starting behaviour, particularly when:
► Drilling from marked centres
► Using handheld drills
► Producing multiple aligned holes
► Drilling metal surfaces
► Position accuracy matters
Correct marking, centre punching where appropriate & secure workholding still play important roles.

A 6mm Hole Doesn't Always Need the Same 6mm Drill
Suppose two workshops both need a 6mm hole.
One is drilling a mild-steel bracket with a cordless drill. The other is repeatedly drilling stainless-steel components.
The diameter is identical, but the cutting conditions are completely different.
Material, thickness, hole depth, drilling equipment, production quantity & chip evacuation all influence which drill is better suited to the job.
That's why two buyers can need exactly the same diameter & still benefit from different Sutton jobber drills.
Handheld Drilling vs Machine Drilling
A pedestal drill provides controlled alignment, stable workholding & more consistent feed.
A handheld drill introduces operator movement, access limitations & changing pressure.
When Drilling by Hand
► Keep the drill square to the work
► Establish the point before increasing pressure
► Avoid excessive side-loading
► Secure the workpiece
► Allow the cutting edges to work
When Drilling by Machine
► Clamp the work securely
► Select a suitable spindle speed
► Check drill condition & runout
► Control the feed
► Manage chip evacuation
► Use appropriate cutting fluid where required
For machine-based drilling, workholding can be just as important as drill selection. Browse Clamps & Vises for suitable workshop holding equipment.
More Speed Doesn't Always Mean Faster Drilling
When a drill isn't cutting well, increasing RPM can feel like the obvious solution.
It can also generate more heat.
Suitable drilling speed depends on the drill diameter, workpiece material, drill construction & cutting conditions. Larger drill diameters generally require lower rotational speeds than smaller diameters when working in the same material.
Listen to the cut. Watch the chips. Pay attention to heat.
A drill that's working correctly should be removing material rather than simply rubbing against the bottom of the hole.
Let the Swarf Tell You What's Happening
Chips aren't just waste.
They can provide useful clues about the drilling process.
Poor chip evacuation can increase heat, interfere with the cutting edges & make deeper holes more difficult.
When drilling deeper holes:
► Give swarf somewhere to escape
► Withdraw the drill where appropriate
► Avoid packing the flutes with chips
► Maintain suitable cutting conditions
► Keep the drill sharp
Different flute designs exist because drilling conditions vary.
The deeper or more repetitive the hole, the more important chip control can become.
When Does a Cobalt Jobber Drill Make Sense?
More demanding metalwork can justify moving beyond general-purpose HSS.
Sutton Heavy Duty Cobalt Jobber Drills are designed for applications where additional heat resistance & durability are valuable.
Consider cobalt when working with:
► Tougher metals
► More demanding drilling conditions
► Repeated metal drilling
► Applications producing higher cutting temperatures
► Workshop jobs where standard HSS is wearing too quickly
Cobalt isn't automatically necessary for every hole.
Choose it when the material & working conditions call for the additional performance.
Jobber Drill, Long Series or Another Drill Type?
A standard jobber drill covers a broad range of everyday drilling jobs, but it isn't the answer to every hole.
Jobber Drill
A practical everyday format where standard reach is suitable.
Long-Series Drill
Useful when additional reach is genuinely required.
Carbide Drill
A specialist option for machining conditions suited to carbide tooling.
Masonry Drill
Designed for brick, masonry, concrete & related materials rather than conventional metal cutting.
Extra length isn't automatically an advantage. Where access allows, using the shortest practical drill can provide a more rigid setup.
Check the Setup Before Blaming the Drill
Poor drilling performance isn't always caused by a worn cutting edge.
Before replacing the drill, check:
► Is the drill sharp?
► Is the chuck gripping correctly?
► Is there excessive runout?
► Is the workpiece moving?
► Is the speed appropriate?
► Is the feed suitable?
► Are chips clearing properly?
► Is the drill appropriate for the material?
A new drill installed into a poor setup can reproduce the same problem.
If the power tool itself isn't performing correctly, Industrial Shed's Power Tool Repairs & Diagnostics can help with the equipment side of the job.
Build Your Drill Collection Around the Sizes You Consume
A complete drill set gives you range.
Individual carded drills keep that set useful.
Pay attention to which sizes disappear from the toolbox first.
A fabrication shop may repeatedly consume common clearance or tapping-drill sizes. A maintenance crew may rely on another handful of diameters every week. A mechanic may consistently reach for only a small group of sizes.
Instead of waiting until those drills are completely unusable, keep frequently consumed diameters ready as replacements.
That turns the drill set into a working system rather than a case slowly filling with gaps.
