Faithfull SDS & Diamond Core Drilling for UK Tradespeople — Dry Core Kit, SDS Bits and Masonry Accessories
Faithfull SDS & Diamond Core Drilling for UK Tradespeople — Dry Core Kit, SDS Bits and Masonry Accessories
Whether you're an electrician cutting holes for back boxes and cables, a plumber routing pipe through masonry, or a builder fixing into blockwork and brick, the right drilling setup makes the difference between a clean finish and a messy job. Faithfull's SDS and diamond core drilling range covers everything from high-speed masonry fixing bits to a professional 7-piece dry core kit — built for tradespeople who drill hard materials every day.
At APM Electricals we stock four key Faithfull drilling products that cover the most common on-site needs: a complete dry core drill kit for precise large-diameter holes, a 10-piece SDS fixing bit set for quick drive-in fixings, a robust SDS-to-BSP adaptor for core barrel compatibility, and a long taper wedge bit for reaching into deep masonry runs.
Why Faithfull for SDS and Core Drilling?
Faithfull Tools has been supplying UK trades for decades, building a reputation for hard-wearing tools at honest prices. Their drilling range is used daily by electricians, plumbers, heating engineers and general builders across Britain — and for good reason. Faithfull bits hold their edge longer than cheap alternatives, the engineering tolerances are tight, and the kits are sensibly specified for real jobs rather than occasional DIY use.
The range stocked at APM Electricals is specifically selected for first-fix electrical and plumbing work: cutting through brickwork for cables, driving fixings into concrete, core drilling for soil stacks and large conduit entries, and reaching deep into walls with extended-length bits.
Faithfull Diamond Dry Core Drill Kit & Case — Set of 7 (FAIDCKIT7)
The Faithfull Diamond Dry Core Drill Kit is the centrepiece of the range for electricians and plumbers who need clean, precise large-diameter holes in brick, block, stone, or aerated concrete. The seven-piece set covers the most common core sizes, all supplied in a robust carry case that keeps bits protected and organised on site.
Diamond dry core bits cut without water cooling — a significant advantage on-site where water suppression is messy and impractical. The dry-cut diamond segments are engineered for use in SDS-Plus or SDS-Max rotary hammer drills in rotation-only mode (no hammer action when core drilling). The segmented crown design clears debris efficiently and reduces heat build-up, extending bit life.
At £89.99 for the complete kit with carry case, this is exceptional value versus buying individual bits — and having the full range on the van means you're never caught out by an unexpected cable diameter or back box size.
Faithfull SDS Masonry Drill Bit Set for Fixings — 10 Piece
For everyday fixing work — dropping in wall plugs, anchoring conduit clips, securing back box mounts — the Faithfull SDS Masonry Drill Bit Set for Fixings gives you a complete set of the sizes you'll reach for most often. Ten bits, all SDS-Plus shank, all sized for standard fixings from 4mm up to the larger diameters used for M8 and M10 anchors.
SDS-Plus bits are the standard for rotary hammers on UK building sites — the bayonet-style chuck delivers hammer blows directly through the bit shank, so you get faster material removal and longer bit life compared to conventional keyless chucks. This Faithfull set uses quality carbide tips brazed to steel shanks, giving consistent performance across hundreds of fixing holes before the tips begin to show wear.
At £34.50 for ten bits, this is a genuinely cost-effective way to equip a new SDS drill or replace a worn set. Store the carry case in the van and you'll always have the right fixing bit to hand.
Faithfull Adaptor SDS x 1/2in BSP
The Faithfull SDS x 1/2in BSP Adaptor is an essential accessory for anyone running core bits that use a 1/2in BSP arbor thread rather than a direct SDS shank. Many traditional core barrel systems — including numerous plumbing and drainage cores — use the BSP thread standard, and without this adaptor you can't drive them from a standard SDS-Plus rotary hammer.
The adaptor locks into any SDS-Plus chuck and presents a 1/2in BSP male thread at the business end. It's machined from hardened steel and rated for the lateral loads involved in core drilling. At £9.95 it's a low-cost solution that opens up a much wider range of core bit compatibility from your existing drill.
If you're using the Faithfull Diamond Dry Core Kit above alongside other core barrel systems, this adaptor ensures you can swap between them without changing chucks or drills.
Faithfull Taper Wedge Masonry Drill Bit 200mm
Sometimes you need to drill through a full brick wall or a deep block course where a standard-length SDS bit simply won't reach. The Faithfull Taper Wedge Masonry Drill Bit 200mm is a 200mm long (8 inch) extended-length masonry bit designed for exactly these situations — particularly useful when drilling through masonry walls for cable entry points, overflow pipes, and first-fix electrics where you need to break through to the other side cleanly.
The taper wedge tip geometry gives this bit aggressive initial bite and reduces wandering when starting the cut. The 200mm overall length means it can drill through a standard double-skin wall without the drill body fouling the brickwork. It's SDS-compatible and built to Faithfull's contract specification — heavy enough for repeated commercial use but priced appropriately at £13.90.
Building the Right Drilling Kit for Electrical and Plumbing Work
For electricians doing first fix in new build or refurbishment, the ideal combination is:
- SDS drill — any quality rotary hammer with SDS-Plus chuck
- 10pc SDS fixing set — for wall plugs, bracket fixings, conduit clips
- Diamond dry core kit — for back box openings, cable entry holes, conduit penetrations
- SDS-BSP adaptor — for compatibility with any BSP-thread core barrels
- 200mm extended bit — for full-thickness wall penetrations where standard bits fall short
This four-product combination from the Faithfull range covers the complete drilling toolkit for most first-fix electrical scenarios — all from a single brand, all available from APM Electricals for next-day delivery to site.
Plumbers routing soil pipes, compression pipe entries and boiler flue penetrations will find the same combination equally valuable, particularly the diamond core kit for larger-diameter holes and the 200mm extension for thick wall construction.
