► ICCONS® | Elongation Rods

Extend Core Drilling Reach for Deeper Concrete Penetrations

When the required drilling depth extends beyond the practical reach of the core bit, changing the entire drilling setup isn't always necessary. ICCONS® | Elongation Rods are B+BTec diamond-coring accessories designed to provide additional reach between compatible core drilling equipment & diamond core bits, helping contractors complete deeper penetrations through concrete & other suitable construction materials.

Built around professional diamond drilling requirements, the ICCONS range includes 300 mm & 500 mm elongation rods with ½" & 1¼" connections to suit compatible crown & segmented core bits. That choice allows operators to match the extension to the existing coring system instead of treating extra drilling depth as a one-size-fits-all requirement.

Deep coring also places greater importance on the surrounding setup. Explore Concrete Cutting & Drilling Tools for related concrete drilling equipment & Dust Extraction & Safety Gear when planning dust-management requirements around suitable site work.

What Are ICCONS® Elongation Rods?

An elongation rod extends the working reach of a compatible diamond core drilling assembly. It connects within the coring system so the operator can reach deeper into the material where the standard core-bit length alone isn't sufficient for the required penetration.

ICCONS supplies these accessories as part of its B+BTec diamond drilling equipment range, which includes professional core bits, drill stands, core drilling machines, water-management equipment, adaptors & other specialist coring accessories.

The documented elongation rod configurations include:

► 300 mm length with ½" connection – minimum bit diameter Ø30 mm
► 500 mm length with ½" connection – minimum bit diameter Ø30 mm
► 300 mm length with 1¼" connection – minimum bit diameter Ø50 mm
► 500 mm length with 1¼" connection – minimum bit diameter Ø50 mm
► Lightweight construction for professional drilling setups
► Compatibility with suitable crown or segmented core-bit systems according to connection

Connection size deserves just as much attention as extension length. A 500 mm rod may provide the reach the hole requires, but the drilling assembly still needs the correct thread connection & minimum compatible core-bit diameter before work begins.

Why Choose ICCONS® Elongation Rods?

Deep drilling becomes a system-selection problem once the standard core bit can no longer reach the required depth. ICCONS elongation rods provide purpose-designed extensions for compatible B+BTec coring equipment rather than relying on improvised methods to increase working reach.

Practical advantages include:

► 300 mm & 500 mm extension options
► ½" & 1¼" connection choices
► Compatibility with suitable diamond core-bit systems
► Lightweight design
► Additional reach for deep core drilling
► Integration with B+BTec professional diamond drilling equipment
► Options for different core-bit diameter requirements

The extension should be selected around the complete drilling assembly rather than depth alone. Core-bit connection, bit diameter, drilling machine, stand arrangement, hole depth, substrate & site conditions all deserve consideration before the rod is fitted.

Common Applications

Deep Concrete Penetrations

Some service penetrations simply need to travel further through concrete than a standard core-bit setup comfortably allows. An elongation rod can provide the additional reach required when drilling through deeper concrete sections with compatible diamond coring equipment.

Before extending the assembly, establish the total required hole depth & determine how much additional working length is actually needed.

Thick Walls & Structural Sections

Wall thickness isn't always obvious from the accessible face of an existing structure. Renovation, infrastructure & commercial construction can involve substantial concrete sections where the operator needs additional reach after the core bit has progressed into the material.

For work around reinforced concrete structures, Concrete Reinforcement provides related products for broader concrete construction requirements.

Service Penetrations

Mechanical, hydraulic & electrical services can require accurately positioned openings through substantial concrete elements. Extended diamond coring can assist where compatible equipment is being used to create deeper penetrations for pipes, conduits or other building services.

Plan the penetration carefully before drilling, particularly where existing reinforcement, embedded services or inaccessible areas may be present beyond the visible surface.

Floor & Slab Coring

A deeper slab can exceed the useful reach of the core bit even when its diameter is already correct for the penetration. Selecting a suitable elongation rod allows additional drilling reach without changing the required hole diameter.

Site conditions beneath the slab must be established before drilling through, especially where the penetration could emerge into an occupied, restricted or service-filled area.

Infrastructure & Civil Work

Heavy concrete construction frequently presents drilling depths that differ from lighter commercial work. Compatible elongation rods can support specialist coring setups used for deeper penetrations where B+BTec diamond drilling equipment has been selected for the application.

The extension remains only one component of the system; drill support, anchoring, water management & core-bit selection still need to suit the job.

Existing Structure Modifications

Retrofitting services into established concrete often introduces conditions that weren't visible when the original structure was built. Deeper coring may be required for new penetrations, but operators should establish the likely drilling path before committing to an extended setup.

Where a penetration relates to subsequent concrete rectification or modification, Concrete Repair & Restoration provides a useful pathway for associated remedial work.

Product Selection Guide

Measure the Additional Reach Required

Choosing the longest extension by default can add unnecessary length to the drilling assembly. Determine the core-bit working length, required penetration depth & additional reach before deciding between the 300 mm & 500 mm options.

Those minimum bit diameters are an important compatibility boundary. ICCONS specifies a minimum Ø30 mm bit diameter for the ½" rods & Ø50 mm for the 1¼" rods, so don't select an extension from thread size & length alone.

Confirm ½" or 1¼" Connection

Thread compatibility is one of the quickest ways to distinguish which elongation rod belongs in the drilling system. ICCONS provides both connection formats because compatible crown & segmented diamond core-bit arrangements use different interfaces.

Before ordering, identify:

► Core-bit connection
► Drilling-machine connection
► Existing adaptors
► Extension length required
► Core-bit diameter
► Complete assembled configuration

Never assume the thread from the outside diameter of the core bit. Check the product specification or existing connection directly.

Match the Rod to the Core Bit

A core bit isn't compatible with an elongation rod simply because the threads appear to connect. Confirm that the bit style, connection & diameter satisfy the requirements of the extension being selected.

ICCONS identifies its elongation rods for use with compatible crown & segmented core bits, with ½" & 1¼" connections available to suit the relevant systems.

Consider the Complete Drilling Length

Adding an extension changes more than the theoretical depth of the hole. The complete assembly becomes longer, which can influence setup space, drill positioning, stand configuration & access around the work area.

Check whether the site provides sufficient clearance to install, operate & withdraw the extended coring assembly safely.

Account for Drill-Stand Setup

As drilling reach increases, equipment control becomes increasingly important. Where a drill stand is required, make sure the stand, drilling machine & mounting arrangement are appropriate for the intended hole diameter, orientation & depth.

B+BTec's wider system includes drill stands, anchoring assemblies, vacuum equipment & related accessories for professional diamond coring applications.

For jobs involving substantial drilling equipment, Heavy-Duty Power Tools provides another relevant equipment pathway.

Plan for Water & Slurry

Deeper wet coring can produce more slurry & place greater importance on controlling water around the drilling area. B+BTec's wider diamond drilling system includes water-management accessories for applicable drilling setups.

Before drilling, consider where water will travel, how slurry will be contained & whether surrounding finished surfaces or occupied areas need protection.

Consider the Hole Beyond the Visible Surface

The deeper the penetration, the more important it becomes to understand what lies along the complete drilling path. Check available drawings, service information & site conditions before committing to an extended core hole.

Where the work requires measurement or accurate set-out before drilling, Surveying & Layout Tools can support the preparation stage.

Expert Tips

Confirm the Minimum Bit Diameter

This is one specification that shouldn't disappear beneath the extension-length decision. ICCONS documents a minimum Ø30 mm bit diameter for its ½" elongation rods & Ø50 mm for its 1¼" rods.

Calculate Depth Before Setting Up

Knowing the required penetration before assembling the drill can save a mid-hole equipment change. Compare the required hole depth with the usable core-bit reach & choose the extension length accordingly.

Inspect Threads Before Assembly

A damaged or contaminated connection can turn a straightforward extension into an avoidable equipment problem. Check the rod, core-bit & machine-side connections before assembly & keep mating threads free from material that could interfere with proper engagement.

Don't Forget Withdrawal Clearance

Reaching the drilling depth is only half the spatial problem—the assembly also has to come back out. Consider overhead, rearward or surrounding clearance when planning an extended drilling setup in plant rooms, confined areas or existing structures.

Treat a Stuck Core Bit as a Separate Problem

More extension length isn't the answer when the core bit itself has become jammed. B+BTec provides a dedicated Core Bit Rescue Tool for compatible 1¼" threaded core bits, helping address stuck tooling without treating the elongation rod as a retrieval device.

Check Reinforcement & Hidden Services

A deeper hole increases the amount of unseen structure the bit may encounter. Review available structural information & service locations before drilling, particularly during retrofit work.

Keep the Coring System Maintained

Diamond drilling equipment works as an assembly, so wear at one connection can affect more than one component. Inspect threads, adaptors, core bits, stands & machine interfaces as part of routine equipment checks rather than looking only at the elongation rod.

For crews maintaining frequently used drilling equipment, tool & equipment Care provides support around workshop equipment care.

Use the Extension for Its Intended Job

An elongation rod is designed to increase core-bit reach, not solve unrelated alignment, retrieval or machine-fit problems. If the system requires an adaptor, rescue tool or different stand configuration, use the component designed for that requirement.
