What Are ICCONS® SDS Max Drilling Bits?
SDS Max is a heavy-duty slotted-drive system used with compatible professional rotary hammers for substantial concrete & masonry drilling. Compared with the smaller SDS Plus interface, SDS Max is designed around higher-capacity equipment used where diameter, depth or drilling load calls for a more substantial system.
Within the ICCONS SDS Max drilling family, buyers can encounter:
► Enduro Trijet configurations across documented 12–16 mm diameters
► Enduro Y-Cutter configurations extending across documented 18–50 mm diameters
► Raptor Ultimate SDS Max 4 Cutter products
► Raptor Ultimate SDS Max Extensions for compatible drilling arrangements
► Set-Safe SDS Max Dust Extraction Drill Bits for applicable dust-controlled drilling
► Multiple working & overall lengths across relevant drill-bit families
These products should not be treated as interchangeable simply because they share an SDS Max shank. Cutting-head geometry, diameter, usable drilling length, concrete condition & the installation being prepared all remain part of correct selection.
Why Choose ICCONS® SDS Max Drilling?
Heavy concrete drilling places substantial demand on the carbide head, flute geometry, machine interface & operator setup. ICCONS provides multiple SDS Max configurations so contractors can select drilling accessories around actual site requirements rather than relying on one general-purpose design.
Depending on the selected product, the range supports requirements such as:
► Large-diameter concrete drilling
► Deep anchor-hole preparation
► Reinforced-concrete applications
► Structural fixing installations
► Commercial construction
► Civil & infrastructure work
► Industrial equipment installation
► Extended-reach drilling
► Dust-controlled drilling on applicable systems
The distinction between SDS Plus & SDS Max is particularly important when specifying equipment. A common SDS designation does not mean the shanks are interchangeable; the drilling accessory must match the compatible rotary-hammer interface as well as the required hole.
Higher drilling capacity should also be selected for a defined reason. Hole specification, substrate, drilling depth & expected workload should determine whether SDS Max is appropriate for the application.
Common Applications
Structural Anchor Preparation
Structural fixing work begins with the hole specified for the anchor system. SDS Max drilling becomes relevant where compatible anchors require substantial diameters, deeper embedment or drilling conditions suited to heavier rotary-hammer equipment.
Confirm the manufacturer's specified drill diameter, minimum hole depth & installation procedure before drilling. The outside diameter of the anchor is not a substitute for the specified drill-bit size.
For associated concrete fixing systems, Anchor Bolts provides a relevant next step once the drilling requirement has been established.
Reinforced Concrete
Reinforcement introduces a different cutting condition from concrete & aggregate alone. ICCONS SDS Max ranges include multi-edge carbide configurations developed for demanding concrete drilling where reinforcement may be encountered.
The ability of suitable tooling to work in reinforced concrete does not determine whether reinforcing steel may be cut. Structural drawings, engineering requirements & site procedures should be checked before penetrating reinforcement.
Deep Concrete Holes
Drilling depth needs to be specified independently from diameter. A bit may have the correct cutting diameter while providing insufficient usable working length for the required penetration.
ICCONS offers SDS Max products across different lengths, together with compatible Raptor Ultimate extension arrangements for applicable drilling systems.
Where additional reach is required, confirm the complete bit & extension configuration rather than assuming any SDS Max extension can be combined with any drill bit.
Base Plates, Columns & Equipment Supports
Heavy steelwork & industrial equipment often rely on accurately positioned post-installed fixings. SDS Max drilling can support preparation for compatible anchor systems used beneath structural brackets, equipment bases, steel supports & other substantial assemblies.
Where the installation continues into heavy fastening hardware, Structural Fasteners & Bolts provides complementary products for broader construction requirements.
Civil & Infrastructure Projects
Repeated drilling into substantial concrete elements places different demands on tooling from occasional installation work. Civil, infrastructure & industrial projects can involve deeper embedment, larger diameters & higher drilling volumes where SDS Max equipment is appropriate.
For crews working at this scale, cutting-head condition, correct machine capacity & availability of commonly used diameters become practical procurement considerations.
Concrete Construction & Retrofit Work
Existing concrete can present conditions that are not apparent from the drilling face. Reinforcement, embedded services, hard aggregate & changes in concrete composition can all influence drilling behaviour during retrofit or modification work.
Where the project involves reinforced-concrete construction more broadly, Concrete Reinforcement provides related construction materials.
Mechanical & Building-Service Supports
Mechanical services, plant installations & substantial support systems can require concrete fixings beyond light-duty installation work. SDS Max drilling provides a professional pathway where the specified anchor diameter, embedment & drilling conditions require heavier equipment.
Before penetrating an existing structural element, verify the drilling location against available drawings, service information & project requirements.
Product Selection Guide
Specify the Hole Before Selecting the Bit

Understand Enduro Trijet & Y-Cutter Selection
ICCONS separates its Enduro SDS Max drilling range according to diameter & cutting-head configuration. Enduro Trijet occupies the documented 12–16 mm sizes, while Enduro Y-Cutter extends from 18 mm through larger documented diameters up to 50 mm.
That distinction provides a practical starting point, but diameter alone should not determine the final choice. Confirm the individual product's working length, overall length, intended substrate & machine requirements before ordering.
Consider Raptor Ultimate 4-Cutter Drilling
Four-cutter geometry provides another professional option within the ICCONS SDS Max range. Raptor Ultimate SDS Max 4 Cutter products are designed around demanding concrete drilling where robust carbide engagement & controlled material removal are important.
For reinforced-concrete work, always separate two questions:
► Is the drill bit suitable for the material?
► Is penetrating the reinforcement permitted by the project?
Both need to be confirmed before work continues.
Confirm Machine Capacity & Connection
SDS Max compatibility begins at the chuck but should not end there. The rotary hammer must provide the correct SDS Max interface while also being suitable for the required bit diameter & workload.
Before ordering, verify:
► SDS Max machine connection
► Recommended drilling capacity of the rotary hammer
► Required hole diameter
► Required working depth
► Substrate
► Reinforcement conditions
► Bit working length
► Dust-management requirements
Using an SDS Max machine outside its recommended drilling range can compromise productivity even when the bit physically fits the chuck.
Check Working Length, Not Just Overall Length
Overall bit length includes sections that do not represent usable hole depth. When drilling for deep anchors or penetrations, compare the required drilling depth with the documented working length of the accessory.
Where a compatible extension is required, include the complete assembled configuration in the selection rather than considering extension length independently.
Plan for Drilling Debris
Increasing hole diameter & depth also increases the amount of material that must leave the cutting zone. Appropriate flute design & drilling technique help move fragmented concrete away from the carbide head during conventional drilling.
For applicable work where source extraction is required, ICCONS' Set-Safe SDS Max Dust Extraction Drill Bit provides a dedicated dust-control pathway.
Dust Extraction & Safety Gear provides additional equipment for managing concrete-drilling environments.
Follow the Anchor Installation Requirements
The finished hole is part of the fixing system, not simply preparation for it. Diameter, depth & cleaning requirements should follow the documentation for the anchor being installed.
This becomes especially important with structural & performance-critical fixings where installation conditions contribute directly to the completed assembly.
For additional practical context, Why Good Fasteners Matter More Than the Tool You Drive Them With explains why fixing performance depends on more than the driving equipment.
Expert Tips
Record High-Use Diameters by Project Type
Procurement becomes more reliable when replacement drilling consumables reflect actual site demand. Track frequently used anchor diameters across structural, mechanical & civil work so critical SDS Max sizes can be replenished before they become unavailable to the crew.
Inspect Carbide Before Specification-Critical Holes
A worn bit can remain operational while no longer being suitable for accurate anchor preparation. Inspect the cutting head, carbide edges, flute condition, shank & overall straightness before drilling holes where dimensions are critical to the fixing.
Verify Reinforcement Before Proceeding
Unexpected steel in the drilling path should trigger a site decision rather than an automatic increase in drilling pressure. Establish whether reinforcement may be penetrated & whether the selected accessory remains appropriate.
Distinguish Working Length From Reach
Deep-hole selection should be based on usable drilling depth rather than the longest physical bit available. Choose sufficient working length for the installation while avoiding unnecessary additional length where it provides no practical benefit.
Treat Extensions as System Components
An extension solves a reach requirement only when it is compatible with the drilling arrangement. Confirm the applicable Raptor Ultimate components & complete assembled length before adding an extension.
Monitor Changes in Drilling Performance
A noticeable reduction in penetration rate can indicate more than hard concrete. Carbide wear, accumulated debris, reinforcement, unsuitable tooling or machine condition should all be considered before increasing operator force.
Prepare the Hole for the Fixing
Removing the drill bit does not necessarily mean the anchor hole is ready. Follow the selected fixing's documented cleaning & installation procedure, particularly where hole cleanliness forms part of the required installation.
Review Equipment Before High-Volume Drilling
Preventive checks are considerably easier to manage before a major concrete-drilling program begins. Inspect rotary hammers, SDS Max shanks, common drill diameters & extraction equipment before committing the system to repetitive site work.
