Ruko core drill D16 mm – HSS core drill with TiAlN coating and 30 mm cutting depth

The Ruko core drill D16 mm is a metalworking core drill designed for reliable holemaking in alloyed and unalloyed steels, high-chrome stainless steels and cast materials, supplied with a Weldon shank for secure clamping

• TiAlN wear-resistant coating
• High-speed steel cutting body
• Weldon shank 3/4" for secure clamping
• 30 mm cutting depth for core holes

Consistent performance through advanced coating technology

The combination of HSS substrate with a TiAlN surface layer increases surface hardness to approximately 3,000 HV and raises hot-hardness up to 900°C, resulting in longer tool life and the ability to run at higher cutting parameters where appropriate. This coating also supports dry machining, reducing coolant dependency and simplifying process logistics. The result is a tool that maintains cutting geometry and dimensional accuracy over extended production runs, contributing to predictable cycle times and fewer tool changes.

Precision dimensions and secure clamping for shop-floor reliability

With a nominal 16 mm diameter, a 30 mm cutting depth and an overall length of 63 mm, the tool integrates readily into production jigs and standard toolholders. The Weldon shank (19.05 mm / 3/4") provides axial security under torque, ensuring concentric clamping and repeatable hole positions in serial work. Five cutting edges balance material removal and chip formation for consistent core extraction and efficient metal removal in interrupted or continuous drilling tasks.

Broad material compatibility and application advantages

The geometry and coating make the tool suitable for unalloyed and alloyed steels up to 1,200 N/mm², high-chrome stainless types such as V2A and V4A, as well as steel castings and tougher brasses. The combination of substrate and coating yields both thermal stability and chemical resistance during contact with hot chips, which helps prevent premature flank wear. For workshops aiming to reduce tool inventory while keeping process capability high, this core drill supports versatile use across typical ferrous and non-ferrous job types.

FAQ

Is this core drill suitable for stainless steel (V2A / V4A)?
Yes. The TiAlN-coated HSS geometry is specified for high-chrome stainless types such as V2A and V4A, so the tool is suitable for those applications.

Can the tool be used without coolant?
The TiAlN surface treatment allows for dry machining in many cases; the tool has been designed to retain hardness and resist thermal wear under reduced-coolant conditions.

What shank does the drill require?
The core drill uses a Weldon shank of 19.05 mm (3/4"), compatible with standard Weldon holders and set-screw clamping systems.

How deep are the cuts the drill will make?
The specified cutting depth is 30 mm with an overall length of 63 mm; this provides a robust margin for through and blind core-drilling in typical workshop setups.
