RUKO annular cutter D14 mm – HSS, 30 mm cutting depth, Weldon shank

The RUKO annular cutter D14 mm is a high-performance core drill designed for efficient, low-wear holemaking in steel, cast iron and non-ferrous metals with a secure Weldon shank connection.

• HSS high-performance material
• 30 mm cutting depth for deep holes
• Weldon 3/4" shank for secure clamping
• Suited for steel, cast iron and non-ferrous

Faster, cleaner holemaking for structural and sheet work

The annular design removes a material ring rather than the full core, which reduces power requirement and cycle times compared with solid twist drills. Constructed from HSS, this cutter combines hardness with toughness to maintain cutting geometry under load. With a 14 mm bore capacity and 30 mm cutting depth, the tool provides a clean bore and reduced burr formation, making it suitable for thin plates and structural sections where a precise finish is required. The result is shorter machining times and less secondary deburring.

Consistent clamping and improved cutting stability

A robust Weldon shank (19.05 mm / 3/4") enables secure fixation in common arbors and holders, which minimises vibration and runout during drilling. The combination of 4 cutting edges and a 63 mm overall length supports a stable cut and predictable chip evacuation, contributing to longer service intervals. Because the cutter is made from high-speed steel, it can be re-sharpened when necessary, extending usable life and lowering overall tooling costs in professional environments.

Practical benefits at the workshop level

Designed for use on steels, cast irons and a wide range of non-ferrous and light alloys, the tool reduces material removal and energy consumption per hole compared with solid drills of equivalent diameter, which benefits throughput and economy on repetitive tasks. The annular cutter’s geometry provides repeatable hole quality for assembly and fabrication work, improving fit-up and reducing rework. For purchasers seeking a reliable, compact holemaking solution, this cutter supports efficient workflows and consistent results across common workshop operations.

FAQ

Is this cutter suitable for drilling structural steel and thicker plates?
The RUKO annular cutter D14 mm is specified for steel work and is suitable for structural sections and plates within its 30 mm cutting depth, offering efficient holemaking with reduced power draw compared with solid drills.

Which shank holders are compatible with the tool?
The cutter uses a Weldon shank (19.05 mm / 3/4"), making it compatible with standard Weldon-style arbors and holders designed for annular cutters.

Can the cutter be used on cast iron and aluminium?
Yes, the tool is intended for a range of materials including cast iron and non-ferrous metals such as aluminium, delivering clean bores when used with appropriate feeds and coolants.

Is resharpening possible to extend service life?
Made from HSS, the cutter can be resharpened by qualified tool service providers to restore edge geometry and extend usable life while maintaining hole quality.

What distinguishes an annular cutter from a twist drill for repetitive holemaking?
An annular cutter removes only a narrow ring of material, producing less volume of chips and requiring less power for a given diameter; this typically yields faster cycles, reduced burrs and improved hole quality for repetitive production tasks.
