RUKO LOS-HSSCo-114mm Bi-Metal Hole Saw 114 mm

The LOS-HSSCo-114mm hole saw from RUKO GMBH is built around a bi-metal construction that pairs high-speed steel cutting teeth with an alloy steel body, delivering a durable cutting edge for professional and industrial applications. Its 114 mm diameter and 41 mm cutting depth make it a practical choice for creating large openings in a range of materials, from wood and metal to plastics and plasterboard.

Highlights

• Bi-metal design: HSS teeth welded to an alloy steel body for enhanced heat and wear resistance.
• T3 Technology tooth geometry with vari-pitch spacing reduces vibration and improves cutting efficiency.
• Speed Slot staircase design allows easy slug ejection after each cut.
• Compatible with Lenox 2L, 5L, or 6L Standard or Speed Slot arbors (5/8"-18 UNF thread).
• Recommended maximum speeds: 500 RPM in wood, 150 RPM in metal.

In daily use

This hole saw is suited for cutting clean, accurate holes in wood, ferrous and non-ferrous metals, plastic, plasterboard, and composites. The welded construction ensures the teeth remain securely attached under load, while the vari-pitch tooth pattern helps to minimize chatter and extend blade life. The Speed Slot feature simplifies removal of the cut-out plug, saving time on repetitive tasks.
