Repeat the Drilling Depth Without Re-Measuring Every Hole

P&N Adjustable Drill Depth Stops provide a simple way to control how far a compatible drill travels into the workpiece. Once adjusted to the required drilling depth, the stop provides a physical depth reference on the drill. P&N designed these accessories for repeatable drilling where multiple holes need to finish at the same depth.

Three individual size ranges cover drills from 3mm through 13mm, while the P&N 3pc set combines all three ranges.

For the drill bits used with the stops, explore P&N Drill Bits. For the power tools behind the drilling setup, Drills & Drivers keeps the other half of the job close.

► Adjustable drill depth stops
► Consistent drilling depth

Three Collar Sizes Cover Drills From 3–13mm

P&N divides its adjustable depth stops into three drill-diameter ranges:

► 3.0–5.0mm — item 149060017
► 5.1–8.0mm — item 149060018
► 8.1–13.0mm — item 149060019

Each individual depth stop is supplied as one piece.

This makes selection straightforward.

Start with the diameter of the drill being used, then select the P&N stop covering that diameter.

The collar range needs to match the drill before the drilling depth is set.

The 3pc Set Brings the Full Range Together

P&N also offers the Adjustable Drill Depth Stop Set 3–13mm 3pc, item 149060020.

The set contains:

► 3.0–5.0mm depth stop
► 5.1–8.0mm depth stop
► 8.1–13.0mm depth stop

Together, the three pieces cover compatible drill diameters from 3mm through 13mm.

The set is useful where drill diameter changes regularly, while an individual stop keeps things simpler when work remains within one diameter range.

Adjustment Comes From the Sleeve

P&N specifies that the drilling depth is adjusted by twisting the sleeve.

That is an important distinction from the old description of these products as hex-key-tightened collars.

The P&N design is adjustable through its sleeve.

Set the stop for the required drilling depth, make sure the setup is correctly positioned on the drill, then check the setting before beginning repeated work.

There is no need to invent another fastening mechanism around the product.

The Stop Controls Depth, Not Hole Diameter

A drill stop does not determine the diameter of the hole.

The drill bit determines diameter.

The depth stop limits drilling travel.

Keeping those functions separate makes the setup easier to understand:

Drill Bit → Hole Diameter

Depth Stop → Drilling Depth

Both need to be selected correctly.

For general drilling accessories used around the same setup, Drill & Driver Accessories provides additional options.

Repeatable Depth Is the Main Job

P&N describes these Adjustable Drill Depth Stops as enabling holes to be drilled consistently to the same depth every time.

That is where the product earns its place.

When several holes require the same depth, repeatedly stopping by eye can introduce unnecessary variation.

A correctly adjusted depth stop gives each drilling operation the same physical reference.

The required depth still needs to be established accurately before drilling begins.

Set the Required Depth Before the First Hole

The first hole should not be the experiment.

Establish the drilling requirement before the bit begins cutting.

Check:

► Required hole depth
► Drill diameter
► Correct P&N depth-stop size
► Position of the stop on the drill
► Workpiece thickness
► Drilling setup

For establishing dimensions before setting the collar, Measuring & Marking provides useful supporting equipment.

Measure first.

Set the depth.

Then verify it.

A Test Hole Can Confirm the Setting

Where the work allows it, a suitable test piece can be useful before moving onto the finished component.

Set the P&N depth stop to the required position, drill the test hole, then confirm the resulting depth.

If adjustment is required, correct the setting before repeated drilling begins.

This is particularly useful when several matching components need the same hole depth.

Once the setting is confirmed, avoid unnecessary changes between holes.

HSS Twist Drills Are Within the Intended Use

P&N specifically identifies HSS twist drills as one of the drill types suitable for its Adjustable Drill Depth Stops.

That gives the stops a useful place alongside conventional drilling setups within the specified 3–13mm diameter range.

The depth stop does not change the intended application of the drill itself.

The HSS drill still needs to suit the material being drilled.

The stop simply provides the depth reference.

For broader drilling work involving metal fabrication, Shop by Trade: Metal Fabrication keeps related equipment around the job.

Brad Point Drills Can Also Use the Depth Stops

P&N also specifies brad point drills as compatible within the applicable diameter range.

Brad point drills have their own cutting geometry plus applications.

The P&N depth stop adds depth control without changing that cutting geometry.

The same setup sequence applies:

► Select the drill
► Confirm its diameter
► Match the correct stop
► Establish the required depth
► Adjust the sleeve
► Verify the setting
► Begin drilling

The accessory stays focused on controlling depth.

Masonry Drills Are Included in P&N's Specification

P&N goes further than conventional twist plus brad point drilling.

The manufacturer also specifies that its Adjustable Drill Depth Stops can be used with masonry drills within the stated 3–13mm diameter range.

That does not turn every drill into a masonry drill.

The actual drill still needs to be appropriate for the material plus drilling method.

For equipment specifically grouped around masonry plus concrete work, Concrete Cutting & Drilling Tools provides the relevant supporting range.

Match the Stop to the Drill Diameter First

Before thinking about depth, identify the drill diameter.

For example:

► A 4mm drill belongs within the 3.0–5.0mm stop range
► A 6mm drill belongs within the 5.1–8.0mm stop range
► A 10mm drill belongs within the 8.1–13.0mm stop range

The three size bands make it unnecessary to treat one collar as though it fits every drill from 3–13mm.

The complete 3pc set provides that overall coverage by combining three separate adjustable stops.

Depth Needs to Suit the Workpiece

The P&N stop can control drilling travel, but the correct depth still comes from the work being performed.

That may depend on:

► Fastener requirements
► Component dimensions
► Material thickness
► Hardware installation
► Pilot-hole requirements
► Existing hole specification

Confirm the required depth rather than assuming a standard setting.

For useful background around screws, bolts plus anchors used with drilled holes, Fastener Guide Bolts Screws Anchors provides additional practical context.

Hole Position Still Matters

Depth control does not correct a hole drilled in the wrong location.

Mark the position before drilling plus make sure repeated components use a consistent layout where required.

A useful sequence is:

Position → Diameter → Depth → Stop Size → Stop Setting

Once those points are established, the drilling operation has both a location plus a depth reference.

The collar handles only one part of that sequence, so accurate setup around it remains important.

Secure the Workpiece Before Drilling

A depth stop is not a workholding device.

The workpiece still needs appropriate support plus restraint for the drilling operation.

Do not use toolboxes, storage cases, mobile cabinets or unrelated workshop equipment as improvised supports simply to raise or brace the work.

Prepare a stable drilling setup suitable for the material plus operation.

The stop should control drill travel.

It should not be expected to compensate for movement in the workpiece.

Do Not Use the Collar to Force the Drill

When the stop reaches its set depth, the purpose is to provide the drilling limit.

Extra downward force does not improve that setting.

If the operation does not feel right, stop plus inspect:

► Stop position
► Drill condition
► Workpiece stability
► Hole depth
► Material
► Power-tool condition

For warning signs that the drill itself may require attention, 7 Signs Your Power Tool Needs a Service Before It Fails on Site covers useful power-tool checks.

Recheck the Setting During Repeated Work

A depth stop is most useful when repeated holes stay consistent.

That makes periodic inspection worthwhile.

After several holes, check that:

► The stop remains correctly positioned
► The required depth has not changed
► The drill remains serviceable
► The workpiece setup remains consistent
► The next hole is correctly marked

If anything has shifted, correct it before continuing.

A short check is easier than discovering a depth problem after an entire run has been drilled.

Keep All Three Sizes Easy to Identify

The individual P&N stops cover clearly separated diameter ranges.

Keeping them organised makes selecting the correct one easier:

3.0–5.0mm

5.1–8.0mm

8.1–13.0mm

If the 3pc set is being used, return each stop to its storage position after the work is finished.

For organising smaller drilling accessories plus frequently used workshop equipment, Tool Storage & Organisation provides practical storage options.

Inspect the Stop Before It Goes Back Into Service

Before fitting a depth stop to the next drill, inspect it.

Check that the sleeve adjusts correctly plus that the accessory is in suitable condition for the intended drilling setup.

If something does not operate as expected, address it before drilling.

The same principle applies to the drill bit plus power tool.

For a broader look at keeping working equipment dependable, A tool is not just a tool. It’s a promise. covers the value of maintaining equipment before it becomes a problem.

Individual Stop or 3pc Set?

The choice is straightforward.

An individual P&N Adjustable Drill Depth Stop makes sense when the drill sizes being used remain within one of the three diameter ranges.

The 3pc set brings all three ranges together when work regularly moves between different drill diameters.

Think in terms of coverage:

► 3.0–5.0mm
► 5.1–8.0mm
► 8.1–13.0mm

The complete set covers all three.

There is no need to add unsupported fixed, precision or hex-key collar categories to explain the range.

Five Checks Before Setting the Drilling Depth

Keep the setup centred on what the product actually controls:

► Diameter — which drill is being used?
► Collar Range — which P&N stop covers that diameter?
► Depth — how deep does the hole need to be?
► Position — where does the hole need to start?
► Setup — is the drill plus workpiece ready for controlled drilling?

Once those points are established, adjust the sleeve to suit the required depth plus verify the setting.
