Efficient Core Setup for Concrete & Masonry Service Holes
When plumbing, electrical or building services need an opening larger than a conventional masonry bit can produce, the complete drilling arrangement matters. ICCONS® | Quick Adaptors & Bits brings together Ratio Quick coring components for suitable concrete & masonry applications, connecting compatible core bits to SDS Plus or SDS Max rotary hammers through purpose-matched adaptors & a dedicated pilot bit.
Choosing the system as an assembly removes much of the uncertainty from larger-diameter drilling. ICCONS documents 50 mm, 65 mm & 80 mm Ratio Quick core bits, a 12 mm Ratio Quick pilot bit plus SDS Plus & SDS Max Ratio Quick adaptors, allowing buyers to specify the required opening separately from the rotary-hammer connection.

What Are ICCONS® Quick Adaptors & Bits?
Ratio Quick is a modular coring system designed to create larger service openings where an ordinary masonry drill bit is no longer the practical tool for the hole. The system combines a core bit, central pilot & machine-specific adaptor so each component performs a defined role during drilling.
The documented ICCONS Ratio Quick range includes:
► 50 mm Ratio Quick Core Bit – HCRCB050
► 65 mm Ratio Quick Core Bit – HCRCB065
► 80 mm Ratio Quick Core Bit – HCRCB080
► 12 mm Ratio Quick Core Pilot Bit – HCRPB12
► Ratio Quick SDS Plus Adaptor – HCRSDSPLUS
► Ratio Quick SDS Max Adaptor – HCRSDSMAX
Component relationships are straightforward once the required hole is established. The core determines the nominal opening diameter, the pilot establishes the centre & the adaptor connects the coring assembly to the appropriate compatible SDS rotary hammer.
That modular arrangement also matters when replacing individual components. A crew may need another core diameter without changing machine connection, or a replacement pilot while retaining the existing adaptor & serviceable core bits.
Why Choose ICCONS® Quick Adaptors & Bits?
Larger service holes introduce purchasing decisions that don't exist with a standard anchor hole. Diameter, drilling depth, substrate, rotary-hammer connection & pilot arrangement all need to work together before the equipment reaches the wall.
ICCONS Ratio Quick gives trades a defined system for applications including:
► Plumbing service penetrations
► Electrical service access
► Pipe openings
► Cable & conduit routes
► Concrete & masonry coring within the applicable system
► SDS Plus rotary-hammer setups
► SDS Max rotary-hammer setups
► Replaceable pilot, core & adaptor components
The ability to separate core diameter from machine connection is particularly useful for trade fleets. A 65 mm opening, for example, establishes the required core size, while the rotary hammer determines whether an SDS Plus or SDS Max adaptor belongs in the assembly.
For crews moving regularly between drilling & fastening work, the Fastener Guide Bolts Screws Anchors provides additional guidance on the relationship between prepared holes & installed hardware.
Common Applications
Plumbing Penetrations
Pipework frequently requires a controlled circular opening rather than a series of smaller drilled holes. Ratio Quick core bits provide 50 mm, 65 mm & 80 mm diameter options that can suit applicable plumbing penetrations through compatible substrates.
Before choosing a diameter, account for the complete installation—not simply the nominal pipe size. Sleeves, insulation, fittings & specified clearance can change the opening actually required.
Electrical & Conduit Access
A new cable route can quickly turn masonry work into a larger-diameter drilling task. Electricians & service installers can configure the Ratio Quick system around the required opening while matching the adaptor to the compatible rotary hammer available on site.
Accurate centre marking becomes especially important around switch rooms, existing services, finished walls or locations where the penetration must align with equipment on the opposite side.
Masonry Service Openings
Brick, block & masonry walls can require dedicated coring when services need to pass cleanly through the structure. The Ratio Quick system provides a purpose-built approach where the substrate, hole diameter & drilling conditions fall within the applicable equipment requirements.
Substrate condition should still be assessed before work begins because different masonry constructions can respond differently during coring.
Renovation & Retrofit Work
Existing buildings rarely offer unlimited freedom when new services need another route. A carefully positioned core opening can support plumbing, electrical or mechanical modifications while limiting unnecessary disturbance around the intended penetration.
When accurate set-out is important before drilling, Measuring & Leveling Tools provides related equipment for establishing positions, heights & alignment.
Mechanical Services
Building-services upgrades often introduce penetrations that weren't part of the original construction. Ratio Quick accessories can support suitable openings where the core diameter, substrate & rotary-hammer configuration align with the system.
If the completed service installation also requires mechanical fastening, Screws & Anchors provides a related pathway into installation hardware.
Maintenance Modifications
One accurately specified opening is preferable to discovering halfway through the job that the available tooling is undersized or incompatible. Maintenance crews can establish the required diameter first, then match the pilot & adaptor to the coring setup already in use.
Keeping the system identifiable also simplifies replacement purchasing when individual components become worn, damaged or separated between vehicles.
Product Selection Guide
Establish the Required Opening Diameter
Start with what must pass through the finished penetration. ICCONS documents three Ratio Quick core-bit diameters:
|
Ratio Quick Component
|
Specification / Role
|
|
HCRCB050 Core Bit
|
50 mm diameter
|
|
HCRCB065 Core Bit
|
65 mm diameter
|
|
HCRCB080 Core Bit
|
80 mm diameter
|
|
HCRPB12 Pilot Bit
|
12 mm pilot / centring component
|
|
HCRSDSPLUS Adaptor
|
Connection for compatible SDS Plus rotary hammer
|
|
HCRSDSMAX Adaptor
|
Connection for compatible SDS Max rotary hammer
|
Nominal service size isn't always the same as required hole size. Confirm sleeves, pipe insulation, conduit fittings, movement allowance & project requirements before deciding between 50 mm, 65 mm & 80 mm.
Match the Adaptor to the Rotary Hammer
After diameter comes machine compatibility. Ratio Quick provides separate SDS Plus & SDS Max adaptors, so identify the actual rotary-hammer chuck before ordering.
Don't choose the adaptor from core diameter. The core answers the opening-size question; the adaptor answers the machine-interface question.
Include the Correct Pilot
A precisely marked centre only helps if the drilling assembly follows it. ICCONS documents the Ratio Quick pilot as a 12 mm × 155 mm component, providing the centring element within the system.
Inspect the pilot before high-accuracy work & replace it when wear or damage begins affecting controlled starts.
Confirm the Material Before Coring
A circular core bit isn't automatically suitable for every substrate that looks like concrete. Material condition, reinforcement & drilling requirements should be established before selecting the system.
ICCONS' current drilling information positions Ratio Quick within concrete & masonry coring applications. More demanding structural or specialist coring conditions should be assessed separately rather than assuming the same setup applies.
Understand Ratio Quick Versus Diamond Coring
Hole shape alone doesn't make two coring systems interchangeable. Ratio Quick works with compatible SDS rotary-hammer equipment, while professional diamond drilling uses a different combination of motors, core bits, stands, water-management equipment & specialist accessories.
Choose according to substrate, penetration depth, required diameter & drilling conditions rather than simply selecting whichever coring system is already nearby.
For broader concrete work where airborne material & site controls need consideration, Dust Extraction & Safety Gear provides relevant supporting equipment.
Inspect the Assembly as a System
Compatibility should be confirmed before the core touches the surface. Check the core, pilot, adaptor & rotary-hammer interface together, paying attention to wear, damage or contamination at mating components.
If one component doesn't seat or operate as intended, identify the cause instead of applying additional force to make the assembly fit.
Expert Tips
Work Backwards From the Service
The fastest way to narrow the core choice is to measure what must ultimately pass through the wall. Determine the finished clearance requirement first, then select the nearest appropriate documented core diameter for the installation.
Verify SDS Plus or SDS Max at the Tool
Visual assumptions are unreliable when several rotary hammers are moving between workshop, vehicle & site. Check the machine model or chuck directly before ordering the Ratio Quick adaptor.
Mark Both Sides Where Conditions Allow
Knowing where the penetration is expected to emerge can reveal problems that aren't obvious from the drilling face. Where access permits, verify the drilling path against the opposite side before beginning.
Check the Pilot Before Precision Work
A worn centring component can undermine careful set-out before the core has properly established itself. Keep the 12 mm Ratio Quick pilot serviceable & replace it when its condition no longer supports controlled drilling.
Investigate Unexpected Resistance
A sudden change in drilling behaviour deserves assessment rather than more feed pressure. Stop & establish whether the cause is substrate variation, reinforcement, a damaged cutting edge or another condition outside the expected drilling path.
Treat Hidden Services as Part of the Drilling Decision
The core doesn't know whether the material ahead contains a cable, pipe or other service. Review available drawings, site information & accessible areas before drilling through an existing structure.
Keep Core Bits, Pilot & Adaptors Together
A complete system can become unusable on site because one inexpensive component was left in another vehicle. Store Ratio Quick components as a recognisable kit & check the required diameters before dispatching equipment to the job.
Tools Storage & Organization provides relevant options for keeping drilling accessories organised between workshop, vehicle & site.
Review High-Use Equipment Before Major Jobs
Consumables & connection components are easier to replace before the drilling schedule becomes urgent. Inspect core cutting edges, pilot condition, adaptors & rotary-hammer interfaces when preparing equipment for upcoming projects.
Spring Jobsite Prep Getting Your Gear Ready provides additional practical guidance for preparing working equipment ahead of demanding site periods.
