Match the bit geometry and tip coating to the substrate. Masonry and concrete require percussion or SDS formats with a carbide tip. Metal calls for HSS or cobalt twist drills, and close-tolerance work in steel often needs a specific metric diameter such as 10.2 mm, 10.5 mm, 11.5 mm, or 12.5 mm. Tile needs a carbide-tipped or diamond-coated bit to avoid cracking the surface. Wood benefits from lip-and-spur or auger geometry for a clean entry. When in doubt, check the material rating printed on the bit packaging.
SDS Plus is the standard percussion format for most rotary hammers used on site, typically suited to holes up to around 26 mm in masonry. SDS Max uses a larger shank with more flute area, designed for heavy-duty hammers drilling larger or deeper holes. The 14 mm x 540 mm long-reach specification listed on this site is an SDS Max format, used where depth clearance is needed through thick concrete or blockwork. The two shanks are not interchangeable, so confirm which chuck system your machine accepts before ordering.
Annular cutters are preferred for larger-diameter holes in structural steel, typically from around 12 mm upward, because they remove only a core rather than the full slug, reducing cutting force and heat. A 22 mm annular cutter produces a cleaner hole with less wear on the machine than a twist drill of the same size. They require a magnetic drill press with the correct arbor fitment. For smaller precision diameters in sheet metal or plate, a quality HSS twist drill remains the practical choice.
Abracs sets listed on PartsForMachines are grouped for general trade use and typically cover a graded metric range rather than a single application diameter. They are a practical option when a van or workshop needs a broad spread of sizes rather than a single precision bit. For a specific diameter not covered by a set, individual bits are listed separately. If you need a quantity above the standard listed pack size, contact the team directly to discuss trade quantities and availability.
Returns are accepted within 30 days of purchase, in original packaging, on orders delivered within the United Kingdom. For damaged-on-arrival items, report within 24 hours with photographs to [email protected] — we will typically arrange collection and replacement at no cost to you. For parts that don't fit your machine, the Fit Guarantee covers a hassle-free return at no cost. For buyer's remorse — you've changed your mind or ordered the wrong item, email us first to obtain a Return Merchandise Number; a restocking fee may apply. Refunds are issued to the original payment method once the return is inspected.
Delivery time depends on the product, your destination, and availability — the estimated time for any item appears on the product page, and 'Check where we deliver' confirms coverage for your postcode before you order. Next-day delivery is available on most products; the option appears at checkout when applicable. We deliver across the UK, Europe, the Middle East, and Africa.

Drill Bits Range
Choosing the right bit for the material and the machine determines whether a hole is clean, fast, and repeatable, or slow and ragged. The Drill Bits Range on PartsForMachines, listed as an Authorised Distributor and Seller, covers five material-specific sub-categories so trade buyers can go straight to the geometry and coating that suits the job.
Masonry carries percussion and SDS formats, including long-reach SDS Max bits such as the 14 mm x 540 mm specification that regularly appears in contractor searches. Metal holds twist drills across the fractional and metric ladder, covering close-tolerance diameters from the mid-tens upward as well as mag-drill annular cutters in sizes like 22 mm. Multi Purpose lists bits suited to mixed-substrate work where a single driver handles several materials. Tile provides carbide-tipped and diamond-coated options for ceramic and porcelain. Wood carries augers, lip-and-spur, and flat bits sized for joinery and first-fix carpentry.
Matching a bit to the application depends on three things: the material being drilled, the shank type accepted by the machine, and the diameter tolerance the job demands. Sets grouped by the Abracs brand offer a practical starting point for general trade use, while individual bits let buyers hit a precise size. If a listed diameter or shank format is not immediately obvious, use Ask Simon on the relevant product page for an instant fitment check.
