RUKO Core Drill Set 7-piece — HSS with TiAlN coating, Weldon shank 19.05 mm (3/4")

The RUKO Core Drill Set 7-piece is a compact annular cutter kit designed for efficient hole production with a 30 mm cutting depth, offering six cutter sizes and a guide pin for safe, repeatable drilling in workshop and maintenance environments

• HSS with TiAlN coating
• Weldon shank 19.05 mm (3/4")
• Cutting depth 30 mm
• Includes guide pin Ø 6.35 x 77 mm

Faster, cleaner holemaking for production workflows

The kit's HSS bodies combined with a TiAlN surface layer reduce friction and heat build-up, enabling steady cutting action and longer tool life under continuous use. CBN-ground cutting edges provide precise geometry that supports rapid metal removal while maintaining hole quality. These characteristics translate into fewer reworks and shorter cycle times, which benefits machining schedules and overall operational efficiency.

Secure clamping and quick tool changes for reliable use

A standard Weldon shank of 19.05 mm (3/4") ensures firm clamping in compatible holders and quick interchangeability on horizontal and vertical drilling setups. The set covers six common diameters (Ø 12–22 mm) and includes a guide pin (Ø 6.35 x 77 mm) sized for the specified cutting depth, allowing centred starts and controlled chip ejection. The compact 7-piece configuration keeps essential sizes close at hand, reducing downtime between operations.

Ready-to-fit kit that supports workshop resilience

Delivered as a complete set, the annular cutters are prepared for direct use in standard Weldon holders and are suited to repetitive tasks where consistent hole geometry is required. The modest 30 mm cutting depth is ideal for through and shallow blind holes, while the assortment of diameters provides flexibility across maintenance, fabrication and general metalworking tasks. The robust finish and ground edges contribute to predictable performance and straightforward re-sharpening where applicable
