RUKO core drill Ø22 mm – HSS with TiAlN, 30 mm cutting depth

The RUKO core drill Ø22 mm is a high-performance annular cutter designed for efficient holemaking in steels and other challenging materials, supplied with a Weldon shank for secure clamping

• TiAlN wear-resistant coating for long life
• High-speed steel body for toughness
• Weldon shank 19.05 mm (3/4") secure clamping
• 30 mm cutting depth for common through-hole needs

Consistent cutting performance under heat and load

The annular cutter is manufactured from HSS and finished with a TiAlN coating, which increases surface hardness to approximately 3,000 HV and raises hot hardness stability up to 900°C. These measurable improvements result in extended tool life and more predictable productivity, particularly when machining unalloyed and alloyed steels (up to roughly 1,200 N/mm²), high-chromium stainless steels such as V2A/V4A, cast steel and tough brass. The coating's thermal and chemical stability supports higher cutting parameters and enables dry machining in many applications, reducing coolant costs and process complexity.

Designed for secure clamping and efficient chip evacuation

With a Weldon shank of 19.05 mm (3/4"), the cutter is intended for toolholders that demand positive torque transmission and fast tool changes; this reduces downtime in serial production. The tool features six cutting edges, which balance cutting aggressiveness with surface finish, while the 30 mm effective cutting depth is suited to most structural and fabrication tasks without compromising stability. The annular geometry removes a material slug rather than pulverising chips, which lowers power draw and shortens cycle times compared with equivalent twist drills.

Practical advantages for workshop and production environments

Engineers and workshop managers benefit from fewer tool changes and more predictable maintenance intervals thanks to the coating and the robust HSS core. The cutter's specifications support both manual fabrication and automated drilling centres, where repeatability and clamp reliability are required. For operations seeking to simplify tooling inventories, the Ø22 mm annular cutter delivers a cost-effective compromise between longevity and process flexibility, enabling confident planning of production runs and reduced machine idle time.

FAQ

What advantages does the TiAlN coating provide?
The TiAlN coating on the RUKO core drill Ø22 mm increases surface hardness and thermal stability, which translates into longer life and higher cutting parameters for steel and stainless steel machining.

Can the cutter be used without coolant?
Yes. The RUKO core drill with TiAlN is suitable for dry machining in many applications owing to its thermal stability and wear resistance.

Which materials are recommended for this annular cutter?
The cutter is recommended for unalloyed and alloyed steels (up to ~1,200 N/mm²), high-chromium stainless steels (V2A/V4A), steel castings and tough brass.

What holder is required for secure clamping?
The tool uses a Weldon shank of 19.05 mm (3/4"), so a Weldon-type holder with matching clamping flat is required for torque transmission and quick tool changes.

How many cutting edges does the tool have and what is the effect?
The core drill has six cutting edges; this geometry provides a balance between cutting efficiency and surface finish while helping to stabilise the cutting action in demanding materials.
