Take advantage of a robust combination of HSS construction, a secure Weldon shank and a complete range of metric diameters for efficient, repeatable core drilling in workshop environments; order the set directly via Metav Werkzeuge or consult the team for application advice. Core Drill Set 7pc D12–22mm (HSS, 30 mm cut depth) – RUKO Core Drill Set D12–22mm for precision hole-making in metalworking and general workshop applications, supplied as a compact kit for immediate use. Solid HSS construction for durability Weldon shank 19.05 mm (3/4") for secure clamping CBN-ground cutting edges for consistent performance Includes pilot pin Ø6.35 x 77 mm for guided drilling Reliable metalworking performance for routine production This RUKO core drill set combines high-speed steel and carefully ground cutters to deliver repeatable, clean cores in common workshop materials. The HSS composition offers a balanced mix of toughness and wear resistance, which reduces the risk of premature wear during short to medium production runs. The set provides a practical diameter spread (Ø12–22 mm) that covers a wide range of typical hole sizes, while the modest 30 mm cut depth keeps the tool well matched to thinner plate and sheet applications. Secure mounting and accurate guidance for safer operation A defining benefit is the Weldon shank (19.05 mm / 3/4"), which enables rigid clamping in compatible holders and reduces slippage under torque. The included pilot pin Ø6.35 x 77 mm ensures centred starts and helps avoid wandering on non-penetrating surfaces. For users unfamiliar with the term, a Weldon shank is a flat-sided holder interface that resists rotation in set screws, offering a more stable connection than plain cylindrical shanks and improving hole accuracy in demanding setups. Cutting-edge edge preparation explained and applied The cutters are CBN-ground, a finishing process that improves edge geometry and run-out stability. CBN grinding produces consistent cutting profiles and a fine edge, meaning less burr formation and cleaner cores. In practice, this translates to shorter secondary operations and higher first-pass acceptance rates—an important advantage in production environments seeking to reduce rework and handling times. Practical kit design for workshop efficiency Packed as a seven-piece kit, the package contains six core drills and one pilot pin, providing immediate utility without needing complementary accessories. The compact range of diameters minimises tool changes while covering common hole sizes for maintenance, fabrication and installation tasks. The Weldon shank standard facilitates quick integration into existing holders and adapters, simplifying tool preparation and reducing downtime between jobs.
