29mm Core Drill HSS 30mm Cutting Depth Weldon Shank - Ruko GmbH

Benefit from the combination of HSS construction, a 29 mm cutting diameter and a robust Weldon shank for reliable hole-making in structural and light-metal workpieces; order the core drill directly via Metav Werkzeuge or ask our consultants if needed.

RUKO annular cutter 29 mm (HSS) – 30 mm cutting depth, Weldon shank

The RUKO annular cutter 29 mm is a high-performance HSS core drill engineered for fast, clean through-hole cutting in steel, cast iron and non-ferrous materials, suited to production and workshop use.

• HSS high-performance steel construction
• 29 mm cutting diameter for larger holes
• 30 mm cutting depth for efficient passes
• Weldon shank 19.05 mm (3/4") for secure clamping

Faster, more efficient hole-making for production lines

The annular cutter is designed to remove a narrow ring of material rather than the full core, which reduces machining time and power draw. The 29 mm cutting diameter combined with a 30 mm cut depth allows for swift through-hole creation in structural steels and plate materials. Because the tool cuts only the material at the hole perimeter, chip evacuation is improved and the required feed force is lower, resulting in shorter cycle times and less wear on the machine spindle. This makes the cutter particularly effective for repetitive operations and CNC-equipped drilling rigs.

Durable cutting performance and predictable tool life

Made from HSS, the cutter offers a balanced combination of toughness and red-hardness that suits intermittent drilling and tougher workpiece materials. The tool has eight flutes to distribute cutting loads and produce consistent chips; this geometry helps maintain cutting edge integrity across repeated cycles. The solid construction of the cutter means repair or regrinding is feasible where appropriate, extending service life and reducing total tooling cost. In everyday workshop use, the result is a reliable tool that supports steady production without unexpected tool failures.

Secure mounting and simplified handling on magnetic and conventional drill rigs

The Weldon shank (19.05 mm / 3/4") provides a positive, abrasion-resistant contact surface for set-screw clamping systems commonly found on magnetic drilling machines and arbors. This reduces slippage under higher torque and eases tool changes during busy shifts. The shank standard also facilitates compatibility with a wide range of arbors and adaptors, enabling rapid integration into existing toolchains. Clear identification of shank size simplifies inventory management and reduces downtime during tool swaps.

Material versatility and application guidance

This cutter is specified for use in steel (including structural sections and large-format plate), cast iron, and a variety of non-ferrous and light metals. The geometry and material choice make it suitable for typical construction and fabrication tasks where clean, burr-minimised holes are required. For optimal results, use appropriate cutting fluid and a correct arbor with secure Weldon clamping; during intermittent high-speed operations the HSS grade offers a good compromise between wear resistance and toughness, avoiding premature chipping in mixed-material workloads.

FAQ

What materials can this annular cutter machine handle?
The RUKO annular cutter 29 mm is suitable for steel (including structural plate), cast iron and various non-ferrous and light metals, making it versatile for fabrication and on-site drilling tasks.

Which shank size is required for clamping this tool?
The cutter uses a Weldon shank of 19.05 mm (3/4"), requiring a set-screw clamp or arbor compatible with that shank diameter for secure mounting.

How deep can the cutter cut in a single pass?
The tool offers a cutting depth of 30 mm, which is specified for efficient through-hole creation in typical workshop materials.

Is the cutter regrindable or refurbishable?
Constructed from HSS with robust flute geometry, the cutter can be reconditioned where appropriate; regrindability depends on wear pattern and workshop capabilities.
