For maintenance operations in energy, offshore, marine, and heavy industry where multiple surface preparation tasks are performed in the same shift or the same location, this battery unification is a meaningful operational change. It consolidates the battery supply chain, reduces spare inventory, and allows battery rotation across tools without compatibility constraints.
The three Ultimate cordless tools — what they do and where they work
Bristle Blaster® Ultimate Cordless
The Bristle Blaster® Ultimate Cordless is a rotary impact surface preparation tool that produces surface cleanliness comparable to SSPC-SP10 / Sa 2½ and creates an anchor profile of 65–85 µm Rz on standard carbon steel — comparable in texture and adhesion performance to the surface produced by abrasive blasting. It operates without abrasive media, which eliminates the containment, disposal, and environmental concerns associated with grit blasting while delivering a surface that meets the cleanliness and profile requirements of most high-performance coating systems — always verify against the specific coating TDS.
The Bristle Blaster® Ultimate Cordless is the primary tool for field joint coating preparation, structural maintenance in remote or elevated locations, and any application where blast-equivalent surface preparation is required without the logistics of a blasting operation. For use in ATEX-classified atmospheres (offshore decks, refineries, petrochemical facilities), the Bristle Blaster® Pneumatic is the appropriate MontiPower tool — it carries ATEX Zone 1 approval (ExII2GcIIAT4X). The cordless Ultimate does not carry ATEX certification.
MBX® Ultimate Cordless
The MBX® Ultimate Cordless is a surface preparation tool for cleaning, rust removal, profiling, and inter-coat preparation on structural steel, process equipment, storage tanks, and marine surfaces. It delivers rotary impact mechanical action suited to maintenance painting preparation, weld zone treatment, and surface conditioning. The MBX® Ultimate Cordless does not carry ATEX certification; for hazardous area environments, the Bristle Blaster® Pneumatic is the designated tool.
Vinyl Zapper® Ultimate Cordless
The Vinyl Zapper® Ultimate Cordless removes decals, adhesive films, markings, and vinyl wraps from vehicle fleets, rolling stock, aircraft ground support equipment, and industrial machinery. It operates mechanically without chemicals or solvents, protecting substrate surfaces and eliminating the safety and disposal requirements associated with chemical stripping agents. The CAS battery platform means the same battery system used across the Bristle Blaster® and MBX® Ultimate tools is also used for Vinyl Zapper® operations — a single battery infrastructure across all three tools.
CAS battery specifications for the Ultimate range
The Ultimate cordless tools operate on MontiPower’s 18 V LiHD battery packs, which are part of the CAS platform. Three capacity options with MontiPower item codes are available:
| Battery pack | MontiPower item code | Voltage | Capacity | Weight | Best for |
|---|---|---|---|---|---|
| LiHD 18 V 5.5 Ah | ZU-600 | 18 V | 5.5 Ah | 0.9 kg / 2.0 lbs | Work at height, confined access, lighter-duty tasks |
| LiHD 18 V 8.0 Ah | ZU-602 | 18 V | 8.0 Ah | 1.0 kg / 2.2 lbs | Continuous surface preparation, high-demand applications |
| LiHD 18 V 10.0 Ah | Consult MontiPower | 18 V | 10.0 Ah | — | Maximum runtime for extended continuous work |
Both packs include a LED capacity indicator with a press-to-check button, thermal protection, and a battery management circuit compatible with CAS chargers. For continuous surface preparation work — particularly with the Bristle Blaster® Ultimate under load on heavily corroded steel — the 8.0 Ah pack is the recommended choice. The 5.5 Ah pack is the better option where pack weight is a handling concern.
Because all three Ultimate tools use the same battery, a team running the full workflow — Bristle Blaster® for primary prep, MBX® for secondary conditioning, Vinyl Zapper® for decal removal on the same asset — manages a single battery inventory. This is particularly relevant on jobs where multiple tools are deployed simultaneously and battery rotation between team members is part of the work plan.
CAS compatibility: what it means in practice for maintenance teams
CAS compatibility means that any CAS-certified battery from any CAS brand is electrically and mechanically compatible with MontiPower Ultimate tools. A Metabo 18 V LiHD battery purchased separately or already in a team’s inventory powers the Bristle Blaster® Ultimate directly. This compatibility is bi-directional: MontiPower LiHD packs (ZU-600 or ZU-602) power any CAS-certified tool from any of the 45+ participating brands.
For operations standardized on CAS as their cordless platform, this means MontiPower Ultimate tools integrate into the existing battery ecosystem without additional procurement. Battery chargers already on site charge MontiPower packs. Battery storage and management processes already in place apply to MontiPower packs. There is no parallel infrastructure for surface preparation equipment.
For operations not yet on CAS, the decision to add MontiPower Ultimate tools is also a decision about which battery platform to adopt — or whether to maintain a separate, smaller battery pool just for surface preparation. The latter is a viable approach for operations that use surface preparation tools infrequently; for operations with regular or intensive surface preparation requirements, CAS platform alignment is the more efficient path.
ATEX certification and CAS: understanding the distinction
CAS is a battery and tool compatibility platform — it does not confer hazardous area certification. ATEX ratings are tool-specific certifications that must be evaluated independently for each tool model. Within the MontiPower range, the Bristle Blaster® Pneumatic holds ATEX Zone 1 approval (ExII2GcIIAT4X) and is the designated tool for use in explosive atmospheres such as offshore platform decks, refinery maintenance zones, and petrochemical classified areas. The Ultimate cordless tools — Bristle Blaster®, MBX®, and Vinyl Zapper® — do not carry ATEX certification and should not be used in ATEX-classified atmospheres.
For procurement specifications that require both a battery-powered cordless tool and ATEX compliance, the relevant selection is the Bristle Blaster® Pneumatic for ATEX environments, and the Bristle Blaster® Ultimate Cordless for general industrial environments where power access is limited but ATEX classification does not apply. Confirm classification requirements for each specific work location before tool selection.
Integrating the Ultimate range into an existing maintenance tool program
Adding MontiPower Ultimate cordless tools to an existing CAS-equipped maintenance program requires no battery infrastructure changes. The practical integration steps are:
- Battery inventory assessment — determine whether existing CAS battery stock (Metabo or other CAS brand packs) is sufficient to support MontiPower Ultimate tools alongside current tools, or whether additional packs are needed for the intended use pattern.
- Charger compatibility — all CAS chargers charge all CAS batteries; no new chargers are needed if CAS chargers are already on site.
- ATEX requirements — if the work location is ATEX-classified, the cordless Ultimate tools are not the appropriate selection. The Bristle Blaster® Pneumatic (ATEX Zone 1, ExII2GcIIAT4X) is the designated MontiPower tool for hazardous area use.
- Accelerator bar selection — the Bristle Blaster® Ultimate Cordless uses the same accelerator bar system as the standard Bristle Blaster® range; existing accelerator bar inventory is compatible.
Key takeaways
- All three MontiPower Ultimate cordless tools — Bristle Blaster®, MBX®, and Vinyl Zapper® — run on the CAS 18 V LiHD platform, sharing a single battery type across the entire surface preparation workflow.
- Battery options are 5.5 Ah (ZU-600, lighter, for access work), 8.0 Ah (ZU-602, higher capacity, for continuous prep), and 10.0 Ah for maximum runtime. All CAS-brand 18 V LiHD packs are interchangeable with MontiPower Ultimate tools.
- The Ultimate cordless tools do not carry ATEX certification. For ATEX-classified environments, the Bristle Blaster® Pneumatic (ATEX Zone 1, ExII2GcIIAT4X) is the correct MontiPower tool selection.
- Operations already running CAS tools can add MontiPower Ultimate machines with zero new battery infrastructure. Battery chargers, storage, and management processes already in place are directly applicable.
