Annular cutter 15 mm HSS – 55 mm cutting depth, Weldon shank (Ruko)

The Annular cutter 15 mm HSS is a high-performance core drill designed for efficient, single-pass hole production in structural steel and light alloys, suited to welded shank holders and magnetic drilling setups

• 15 mm diameter for precision holes
• 55 mm cutting depth for deep-core drilling
• Weldon shank 19.05 mm (3/4") for secure clamping
• Made from HSS for wear resistance

Faster, more accurate hole production for fabricators

Manufactured from HSS, this annular cutter delivers stable cutting behaviour and consistent hole quality. The combination of 15 mm diameter and 55 mm cutting depth reduces the need for subsequent reaming, allowing one-pass holemaking where appropriate. The tool’s four cutting edges distribute cutting forces evenly, which lowers feed resistance and supports higher productivity on repetitive tasks. For workshop managers and production engineers this translates into measurable time savings on line operations and reduced tool-change frequency.

Secure clamping to maintain concentricity and reduce runout

The Weldon shank connection, specified at 19.05 mm (3/4"), ensures a positive mechanical lock in compatible holders and magnetic drilling machines. This shank format minimises axial play and helps maintain secure clamping under heavy feed, which is essential for repeatable centre accuracy and prolonging cutter life. Where concentricity is critical, the Weldon interface offers a straightforward way to reduce vibration and protect both tool and workpiece.

Broad material compatibility for versatile workshop use

This core drill is specified for a range of materials including steel (suitable for T‑sections and large-format plates), cast steel, non‑ferrous metals and light metals. The uncoated HSS body provides a good balance of toughness and wear resistance across these substrates; it is particularly effective where heat resistance and edge integrity are required during interrupted cuts or through-thickness drilling. The cutter’s profile supports fibre‑free edges in non‑ferrous materials and avoids excessive built-up edge in mild steels.

Improved workflow and dependable supply from a precision partner

With an overall length 88 mm and single-unit packaging, the tool integrates easily into job-specific tool sets. Its construction supports reliable single‑pass core removal, reducing cycle times on repetitive holemaking. As a product from Ruko, stocked and distributed via Metav Werkzeuge, availability is supported by a considered supply chain and expert technical guidance. For procurement teams this combination of proven tool geometry and dependable logistics helps minimise production interruptions and simplifies inventory choices for precision drilling supplies.
