COVER STORY C


lipacore’s relaunched range, distributed by Carl Kammerling International (CKI) and Nerrad Tools, tackles this head-on with its patented Fit>Clip>Core system — a mechanical clip interface that replaces the traditional threaded connection between arbor and core bit entirely. No more relying purely on friction. No more over- tightening. No more fighting your own kit after every hole.


How it works


Fit the adapters once. Clip the core on. Drill. That’s it. The locking mechanism holds firm under load


but releases cleanly by hand when the job’s done - no spanners, no improvised leverage, no seized threads. The mechanical connection is built to handle the torque of masonry drilling while still allowing fast separation when you need to change size or pack away. For multi-hole installations - boiler flues, soil


pipes, ventilation ducting - swapping core sizes takes seconds rather than minutes. You’re not stopping to undo a binding thread or searching for the right tool to free a stuck connection. On a ladder, in a loft, or working in a tight service void, that efficiency adds up quickly. It’s a simple shift in design, but in practice it changes the rhythm of coring work entirely.


Safety and longevity


Beyond speed, the safety case for Clipacore is straightforward. Traditional core bits self-tighten during drilling due to vibration and torque transfer. By the time you’ve cut through dense brick or block, the threaded connection can be locked solid. Attempting to separate the seized core bits means you’re wrestling with your equipment on site, taking up more time and time is money. By removing the need to unscrew the cores after every hole drilled and using the tool-free quick release system instead; you remove the temptation to reach for an improvised method; which is where damaged equipment and strained wrists tend to come from. Durability benefits too. Repeated tightening and loosening gradually degrades threaded connections. Add masonry dust and constant vibration, and wear accelerates further. Over time, threads bind, engagement becomes inconsistent and replacement becomes inevitable. The clip interface bypasses that constant wear cycle between core and arbor, keeping engagement consistent and removing the need to unscrew the threads.


Built for real-world drilling


The refreshed range isn’t just about the quick- release interface. Clipacore also includes Xpresscut dry diamond core bits designed for efficient, controlled penetration through most building materials you’ll come across in the UK and Ireland. With their spiralled and slotted barrels, these


cores are made for effective debris clearance and reduce to drag, to allow for faster and smoother

Stop fighting your core drill — Clipacore’s quick-release system changes the game


If you’ve ever had a core bit seize on an extension bar mid-job, you’ll know the frustration: wrong tools to hand, wasted time, and a very real risk of injury trying to separate components that have practically welded themselves together under torque. It’s a problem most installers accept as part of the job — until something better comes along


industry thread sizes, allowing them to integrate with core bits and drills you likely already own You don’t need to scrap your existing kit to benefit from Fit>Clip>Core system. Instead, you can upgrade incrementally, adding Clipacore adapters into your current setup while maintaining flexibility with standard equipment where required. That practical approach makes adoption


straightforward rather than a major investment decision.


drilling - particularly useful when coring overhead or at awkward angles. The wider system includes extension kits,


ChuckAway adaptors and specialized solutions such as Duocut Pro, Fluemate Pro and Condensemate Pro - offering a complete coring solution rather than a single upgrade to your kit.


No need to start from scratch


Importantly, Clipacore was designed with compatibility in mind. The adapters use universal


Rethinking the process


Clipacore isn’t simply a redesign of products already on the market, it represents a rethink of how core drilling is done on site. By addressing real, day-to- day frustrations, seized threads, wasted time and avoidable strain, the system delivers measurable improvements where they matter most. The refreshed Clipacore range is available now


through CKI and Nerrad Tools. Discover the new Clipacore range today at www.clipacore.com and experience core drilling made effortless, every job, every time.
