Annular Cutter D60 mm HSS, 55 mm Cutting Depth (Weldon) – Ruko

The Annular Cutter D60 mm HSS is a high-performance core drill designed for efficient, low‑distortion holemaking in steelwork, cast iron and light metals, fitted with a 3/4" Weldon shank for secure machine attachment.

• HSS for high wear resistance
• 60 mm diameter for large holes
• 55 mm effective cutting depth
• Weldon 3/4" shank for secure clamping

Faster, cleaner large‑hole production with proven material technology

Manufactured from HSS, this annular cutter offers a balance of toughness and hardness that supports sustained cutting under load. The 60 mm diameter combined with a 55 mm cutting depth reduces the need for multiple operations when producing large clear holes in profiles and plates, enabling shorter cycle times and fewer secondary processes. The material choice means the tool tolerates intermittent impacts and higher heat levels compared with standard carbon steels, resulting in consistently clean hole boundaries and a reduced need for finishing passes. By focusing on effective, single‑pass holemaking, the cutter directly improves throughput on magnetic drills and pillar drills used in fabrication shops.

Secure machine integration for repeatable hole accuracy

The Weldon shank (19.05 mm / 3/4") ensures fast, reliable clamping in compatible chucks and holders; the flats accept a grub screw to prevent slippage and minimise runout. Stable fixation translates into repeatable hole quality, lower tool vibration and a reduced risk of workpiece damage during drilling. For production environments where reproducibility matters, the shank design speeds tool changes and maintains concentricity under load. The mechanical interface also simplifies automation or semi‑automated set‑ups where robust attachment and predictable performance are essential.

Versatile application across metals with practical handling notes

This cutter is suitable for machining steel, cast iron and assorted non‑ferrous metals, including aluminium and brass, as noted by the product specification. As an annular cutter it removes a ring of material rather than producing a full‑diameter swarf, lowering power draw and improving chip evacuation on thicker sections. For best results on thicker or structural elements, use a steady feed and an appropriate cutting fluid to support chip removal and heat control. For delicate light‑metal work, moderate spindle speeds and controlled feed will preserve surface finish while maintaining efficient penetration.

Long service life through reconditioning and correct practice

A further practical advantage is the resharpenable nature of HSS tooling: worn cutting lips can be reconditioned, restoring geometry and extending service life compared with many brazed or coated alternatives. Regular inspection of the cutting edges and prompt regrinding maintain hole quality and dimensional accuracy, supporting cost efficiency over multiple tool lifecycles. Combined with the secure Weldon shank interface, maintenance routines are straightforward and downtime for tool changes or reconditioning is kept to a minimum, supporting a reliable production flow.

FAQ

What materials can this annular cutter machine?
The annular cutter is suitable for machining steel, cast iron and non‑ferrous metals; the HSS construction supports routine use on structural steel and light alloys.

Is the shank compatible with magnetic drills?
The cutter is supplied with a Weldon shank (19.05 mm / 3/4"), designed for secure clamping in holders that accept Weldon‑style flats, commonly used on magnetic drills and pillar drill chucks.

Can the cutter be resharpened?
Yes, the HSS body is resharpenable; reconditioning the cutting edges restores geometry and extends service life while maintaining hole quality.

What hole depth and diameter does the tool provide?
The tool provides a 60 mm hole diameter with an effective cutting depth of 55 mm, suitable for many plate and profile applications where a single‑pass hole is required.

Is a coating applied to improve wear resistance?
No coating is specified for this tool; wear performance relies on the HSS material and correct machining practice, including suitable coolant and feeds.
