RUKO Annular Cutter Ø35 mm HSS — 55 mm cutting depth, Weldon shank

The RUKO Annular Cutter Ø35 mm HSS is a high-performance core drill designed for producing accurate, burr‑reduced holes in steel and non‑ferrous metals in industrial and workshop environments.

• HSS high-performance cutting material
• 55 mm cutting depth
• Weldon shank 19.05 mm (3/4")
• Suitable for steel, cast iron and non-ferrous metals

Faster, cleaner holemaking for heavy‑duty metalwork

Manufactured from HSS, this annular cutter combines material toughness with a geometry optimised for chip evacuation, enabling shorter cycle times and fewer re‑works. The Ø35 mm diameter paired with a 55 mm cutting depth produces a clean, precise bore while removing only the material core rather than the entire hole volume, which lowers power demands compared with solid twist drills. The nine cutting edges contribute to a steady cut and reduced surface finishing work, so production runs maintain consistent throughput and dimensional accuracy without excessive post‑processing.

Secure clamping and consistent bore quality

The Weldon shank design (19.05 mm / 3/4") ensures rigid seating in magnetic drill chucks and compatible toolholders, reducing runout and vibration during drilling. Stable clamping preserves the cutting geometry for longer tool life and enables consistently accurate hole placement when working on structural parts such as T‑beams or large plates. The overall length of 88 mm provides sufficient reach for most setups while keeping the tool mass low, supporting dependable performance in repetitive tasks and demanding fabrication environments.

Versatile compatibility across workshop materials

This core drill is specified for a broad range of metals: steel (including structural profiles and large sheets), cast iron, and various non‑ferrous metals such as aluminium and brass. The cutter’s construction and edge geometry make it suitable for both maintenance and production contexts, from fabricators to mechanical workshops. For less experienced users, annular cutters produce a pilot‑free bore method: the tool removes the material ring and leaves a solid slug that is ejected, which often yields faster holemaking than conventional twist drills for large diameters and minimises heat build‑up in the workpiece.

FAQ

What hole size does this cutter produce?
The cutter produces a bore of 35 mm diameter; the RUKO annular cutter Ø35 mm HSS (SKU 4000602466NW) is intended for precise Ø35 mm holes.

What is the effective drilling depth?
The tool offers a 55 mm cutting depth, with an overall length of 88 mm allowing sufficient reach for typical workshop applications.

Which shank type is required for installation?
A Weldon 19.05 mm (3/4") chuck or adapter is required to secure the cutter for reliable operation.

Which materials can be machined with this cutter?
This annular cutter is suitable for steel, cast iron and non‑ferrous metals such as aluminium and brass in fabrication and maintenance tasks.

How does an annular cutter compare to a twist drill for large holes?
Annular cutters remove only the material ring, producing cleaner holes with less power and shorter cycle times than equivalent twist drills for larger diameters; they also reduce burr formation and finishing work.
